Abstract
Description
- The present invention relates to an electronic cooling type refrigerator directed to a portable cooler or cooling box for cooling the inside of the box by utilizing Peltier effect of an electronic type thermo-module using thermo-electric cooling elements.
- An electronic cooling type refrigerator is known in Japanese Patent Publication (KOKOKU) No. 5-17469, wherein an electronic type thermo-module using thermo-electric cooling elements is assembled in a heat insulating housing or box of the refrigerator for cooling the inside of the housing by utilizing Peltier effect of the thermo-module.
- Figs. 3 and 4 show a structure of a conventional electronic cooling type cooling box, wherein numeral 1 is a heat insulating housing and
numeral 2 is a lid thereof. In a side wall of the heat insulating housing 1, an electronic type thermo-module 3 having a plain plate shape and formed of thermo-electric cooling elements is assembled such that a heat absorbing side of the thermo-module 3 is oriented inside the housing 1 and the heat radiating side thereof is oriented outside the housing 1. - The thermo-
module 3 is a plain shape module, which is formed of a plurality of the thermo-electric cooling elements assembled in series. Each cooling element is formed such that P type and N type semiconductor elements are connected between two ceramic base boards in the form of a small character pi in a Greek letter. - A
heat absorbing member 4 with fins is heat-conductively fixed to the heat absorbing side of the thermo-module 3, and aheat radiating member 5 with fins is heat-conductively fixed to the heat radiating side thereof Awind channel 6 is formed outside the housing 1 to surround thefins 5a of theheat radiating member 5, and anoutside fan 7 is attached to thewind channel 6 to supply outer air to thefins 5a. Numeral 8 is a direct current electric source, such as a battery, to supply electricity to the thermo-module 3. - In the conventional electronic cooling type refrigerator as stated above, since heat exchange between air inside the housing 1 and the
heat absorbing member 4 is made based on a natural air convection, heat exchange efficiency is low. Thus, the cooling efficiency of the electronic type thermo-module has not been sufficiently obtained. - The present invention has been made with reference to the above drawbacks, and is to provide an electronic cooling type refrigerator, wherein the ability to keep cooling inside the refrigerator is improved, and the refrigerator can be used easily.
- In order to accomplish the above object, the electronic cooling type refrigerator of the invention has the following structures;
- (1) The refrigerator includes at the inner side thereof a heat absorbing member with fins heat-conductively connected to a heat absorbing side of an electronic type thermo-module, and an inner fan for forcibly supplying air in the refrigerator to the fins of the heat absorbing member arranged in rows.
- (2) In the structure as stated in the above paragraph (1), the inner fan is assembled inside the fins of the heat absorbing member.
- (3) In the structure as stated in the above paragraph (1), the thermo-module is vertically arranged and is installed in a wall of a housing of the refrigerator, and the fins of the heat absorbing member connected to the heat absorbing side of the thermo-module are arranged vertically. Also, a drain receiver is provided at a lower side of the heat absorbing member for receiving dew dropping from the fins arranged in the rows and draining outside the housing.
- (4) A plurality of electronic type thermo-modules is heat- conductively laminated and is assembled in the heat insulating housing.
- In the above structure, air inside the housing is forcibly supplied by the inner fan to the rows of the fins of the heat absorbing member projecting into the housing, so that heat exchange rate between the heat absorbing member and air inside the housing is increased several times when comparing the natural convection system. Thus, it is possible to sufficiently exhibit the cooling ability of the electronic type thermo-module. Since the inner fan is installed inside the fins of the heat absorbing member arranged in the rows, the limited space inside the housing is effectively utilized.
- Also, a plurality of electronic type thermo-modules is laminated and arranged together as the thermo-module, so that the difference of temperature between the heat absorbing side and the heat radiating side is effectively increased. Thus, the cooling ability can be increased. Also, the fins of the heat absorbing member is vertically arranged, and the drain receiver is provided at the lower side of the heat absorbing member for receiving the dew flowing along and dropping from the fins and discharging the dew outside the housing. Thus, it is possible to easily discharge the dew formed on the surfaces of the heat absorbing fins to the outside of the housing through the drain receiver.

- Fig. 1 is a vertical section view for showing a structure of an embodiment of the invention;
- Fig. 2 is a lateral section view of the embodiment shown in Fig. 1;
- Fig. 3 is a vertical section view for showing a structure of a conventional electronic cooling type refrigerator; and
- Fig. 4 is a lateral section view of the refrigerator shown in Fig. 3.
- The embodiment of the invention is explained herein below with reference to Figs. 1 and 2. In the drawings, the same members as shown in Figs. 3 and 4 have the same numerals.
- Namely, in the structure of the embodiment as shown in the drawings, an electronic type thermo-
module 3 in a plain plate shape is vertically built or installed in a side wall of a heat insulating housing 1 such that a heat absorbing side is directed inside the housing 1. Aheat absorbing member 4 with fins 4a (aluminum extruded product) is heat-conductively fixed to the thermo-module 3 at the inside of the housing 1. An inner fan 9 is built in the fins 4a or the rows of the fins 4a of theheat absorbing member 4. Air inside the housing 1 is forcibly supplied to the fins 4a of theheat absorbing member 4 by the inner fan 9. - On the other hand, a heat radiating side of the thermo-
module 3 is connected to aheat pipe 11 through aheat radiating block 10, and theheat pipe 11 extends to an inside of awind channel 6. Radiatingfins 11a of theheat pipe 11 are cooled by anouter fan 7. Further, the fins 4a of theheat absorbing member 4 are arranged vertically, and the lower portions thereof are cut diagonally. Adrain receiver 12 is provided below the fins 4a, and a drain pipe 12a extending from thedrain receiver 12 penetrates through the housing 1 and is drawn outside the housing. - In the above structure, when an electricity is supplied to the electronic thermo-
module 3 in a predetermined direction from a directcurrent source 8, heat absorption occurs inside the housing and heat radiation occurs outside the housing to thereby cool theheat absorbing member 4 by Peltier effect known already. The heat generated from the thermo-module 3 is radiated to atmosphere through theheat pipe 11. - On the other hand, inside the housing, air in the housing is forcibly circulated by the inner fan 9, which is operated by means of the direct
current source 8, toward the fins 4a of the absorbingmember 4, so that high energy exchange is made. Thus, the space inside the housing is effectively and equally cooled. - Dew formed on the surfaces of the fins of the
heat absorbing member 4 due to cooling of the inside of the housing flows along the surfaces of the fins 4a and drops from the lower ends thereof diagonally cut to thedrain receiver 12, which is then discharged outside the housing through the drain pipe 12a. Thus, inconveniences, such as accumulation of water in the housing 1, do not occur. - The electronic type thermo-
module 3 in the plain shape generally sold in a market has a thickness of about 3.5-5 mm and the heat absorbing side and the heat radiating side are electrically isolated by a ceramic plate with high heat-conductivity. The difference of the temperature between the heat absorbing side and the heat radiating side is slightly above ten degrees centigrade. Therefore, in a cooler or cooling box used outside a house with high atmospheric temperature in a summer time, sufficient cooling ability may not be obtained if one thermo-module is used, though it depends on the capacity of the cooler. - Therefore, in the present invention, a plurality (two or three) of thermo-modules is heat-conductively laminated together and assembled in the housing 1, so that the temperature difference between the inside and outside of the housing is effectively increased to thereby strengthen the cooling efficiency. In this case, it is preferable to reduce the heat conductive resistance by, for example, coating heat conductive grease between the contact surfaces of the respective thermo- modules.
- Incidentally, the above example refers to a portable cooler or a cooling box, but the present invention may be used as a refrigerator with a small capacity fixed in a guest room of a hotel, or a cooling and heating box for cooling or heating the inside of the box by changing the direction of electricity supplied to the electronic thermo-module.
- As explained above, in accordance with the structure of the invention, the following advantages are obtained:
- (1) The inner fan is installed inside the housing, and air inside the housing is forcibly supplied toward the heat absorbing member with the fins, which is heat-conductively attached to the electronic thermo-module. Thus, it is possible to increase the heat exchange efficiency several times more than the conventional natural convection system to thereby efficiently cool the inside of the housing. Also, since the inner fan is built in the fins of the heat absorbing member arranged in the rows, the housing space can be effectively utilized.
- (2) Also, since the drain receiver is provided under the heat absorbing member, it is convenient to drain dew formed on the surfaces of the fins outside the housing.
- (3) Since a plurality of the electronic type thermo-modules is laminated in use, the temperature difference between the heat absorbing side and the heat radiating side is increased to thereby improve the cooling efficiency.
