Abstract
The utility model relates to a semiconductor refrigerating and heating box which is composed of a box body, a box cover, semiconductor refrigerating and heating blocks, temperature conducting blocks, a heat radiator, a fan, a transfer switch, etc., wherein, the surface of the heat radiator is densely distributed with heat radiating columns, and the number of the semiconductor refrigerating and heating blocks is two times of number needed by the rated load. With the adoption of design, the utility model has the characteristics of high heat-radiating efficiency, reliable performance and long service life.
Description
The utility model relates to a kind of improved semiconductor cold and warm box, belongs to the semiconductor refrigerating technology field.
The semiconductor cold and warm box is a kind of electric equipment that is used for food storage commonly used, its operation principle and structure are: utilize Peltier effect, two kinds of dissimilar semi-conductor electricity couples are passed to direct current, make it to take place power conversion, the result emits heat, absorbs heat at another tip side at a tip side; When changing the sense of current, can make that release end of heat becomes heat absorbing end, heat absorbing end becomes release end of heat.With this Cooling and Heat Source as cold and warm box, with the one side of the hot piece of semiconductor refrigerating by temperature conducting block glued joint on the cold and warm box inner bag, another side glueds joint radiator, force heat radiation by air-cooled, make the hot piece of semiconductor refrigerating in the temperature range that allows, normally carry out power conversion.This kind cold and warm box is subjected to body structure size and weight limits, and radiator and ventilating fan size can not be excessive, thereby radiating efficiency is lower.During the broiling summer, the hot piece of semiconductor refrigerating often because of the too high damage too early of temperature, has influenced the normal use of cold and warm box when operating at full capacity.Improving the radiating efficiency of radiator, prolong the service life of the hot piece of semiconductor refrigerating, is to make this product satisfy the key point of instructions for use.
The purpose of this utility model is to provide the semiconductor cold and warm box that a kind of radiating efficiency is higher, service life is long.
The purpose of this utility model is achieved in that
A kind of semiconductor cold and warm box, it comprises casing, case lid, the hot piece of semiconductor refrigerating, temperature conducting block, radiator, ventilating fan, fan housing, change-over switch etc., its improvement is that the radiating surface of described radiator 7 is provided with densely covered thermal column 7-1.
Above-mentioned cold and warm box, the shape of described thermal column 7-1 can be square, cylindrical, cone shape, prismatic or rib vertebra shape etc.
Above-mentioned cold and warm box, the cross section of described thermal column 7-1 are square, and the length of side is the 3-5 millimeter, highly is the 5-25 millimeter.
For reducing the service load of every block semiconductor refrigerating heating block, above-mentioned cold and warm box, the quantity of the hot piece 6 of used semiconductor refrigerating is 2 times of rated power requirement.
The structural design of thermal column on the utility model spreader surface increases the ventilation and heat area of radiator greatly; The quantity of every hot piece of the required semiconductor refrigerating of cold and warm box increases to the 2n piece by the n piece, has reduced every service load effectively, make cold and warm box have radiating efficiency height, power consumption low, use advantage reliable, that the life-span is long.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation;
Fig. 2 is the front view of radiator 7.
As shown in the figure, case lid 3 is hinged on the casing plastic casing 1, box liner 2 is the container of aluminium matter, plastic casing 1 extends to the upper end wall of inner bag 2, be respectively equipped with the magnet 12 that is respectively equipped with mutual adhesive on sealing seam and sealing felt pan 13, the opening end on the sealing surface of casing and case lid, heat-insulation layer 4 is that the foaming of 40% polyester amine forms by density, and whole box body has good sealing heat-insulating property.
Temperature conducting block 5 is affixed on the outside wall surface of inner bag 2, and the one side of the hot piece 6 of semiconductor refrigerating is fitted with temperature conducting block 5 applyings, another side and radiator 7, and each binding face firmly glues together with heat-conducting silicone grease glue, and is also further fixing by screw 10 between temperature conducting block and the inner bag.In view of the hot piece of semiconductor refrigerating in use often bad because of dispelling the heat, higher temperature down at full capacity or overwork and damaging too early, therefore, the utility model is except improving radiator heat-dissipation efficient, also taked to reduce the measure of the hot piece load of semiconductor refrigerating, the quantity of the hot piece of semiconductor refrigerating that uses is 2 times of the rated power requirement, be about to one of former use and become 2 of uses, 2 block semiconductor refrigerating heating blocks 6 be shaped as rectangle, equal and opposite in direction, smooth between temperature conducting block 5 and radiator 7, temperature conducting block, radiator is aluminium matter, the cross section of radiator 7 is a square, the length of side is 100 millimeters, gross thickness together with thermal column is 25 millimeters, and the cross section of thermal column 7-1 is a square on its radiating surface, the length of side is 4 millimeters.The shape of thermal column 7-1 is also cylindrical, cone shape, prismatic, rib vertebra shape etc.
Ventilating fan 8, change-over switch 11 all are fixed on the fan housing 9, and uniform ventilation fence on fan housing 9 covers can be realized the quick circulation of air.
The utility model volume is that 50 liters, power are 48W, and power supply is a 12-24 volt direct current, can directly connect with the dc source on the automobile, and minimum refrigerated storage temperature reaches 4 ℃, and is easy to use, and dependable performance belongs to energy-efficient regeneration product.
