Definitions
- 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.
- 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.
- numeral 1 is a heat insulating housing
- numeral 2 is a lid thereof.
- 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.
- 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.
- thermo-module 3 A heat absorbing member 4 with fins is heat-conductively fixed to the heat absorbing side of the thermo-module 3, and a heat radiating member 5 with fins is heat-conductively fixed to the heat radiating side thereof
- a wind channel 6 is formed outside the housing 1 to surround the fins 5a of the heat radiating member 5, and an outside fan 7 is attached to the wind channel 6 to supply outer air to the fins 5a.
- Numeral 8 is a direct current electric source, such as a battery, to supply electricity to the thermo-module 3.
- thermo-module 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.
- the electronic cooling type refrigerator of the invention has the following structures;
- 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.
- 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.
- thermo-modules 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.
- the cooling ability can be increased.
- 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.
- 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.
- 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.
- a heat 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 the heat absorbing member 4. Air inside the housing 1 is forcibly supplied to the fins 4a of the heat absorbing member 4 by the inner fan 9.
- thermo-module 3 a heat radiating side of the thermo-module 3 is connected to a heat pipe 11 through a heat radiating block 10, and the heat pipe 11 extends to an inside of a wind channel 6.
- Radiating fins 11a of the heat pipe 11 are cooled by an outer fan 7.
- the fins 4a of the heat absorbing member 4 are arranged vertically, and the lower portions thereof are cut diagonally.
- a drain receiver 12 is provided below the fins 4a, and a drain pipe 12a extending from the drain receiver 12 penetrates through the housing 1 and is drawn outside the housing.
- thermo-module 3 when an electricity is supplied to the electronic thermo-module 3 in a predetermined direction from a direct current source 8, heat absorption occurs inside the housing and heat radiation occurs outside the housing to thereby cool the heat absorbing member 4 by Peltier effect known already.
- the heat generated from the thermo-module 3 is radiated to atmosphere through the heat pipe 11.
- 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 the drain receiver 12, which is then discharged outside the housing through the drain pipe 12a.
- inconveniences, such as accumulation of water in the housing 1 do not occur.
- 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.
- thermo-modules 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.
- 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.
