Embodiment Construction

[0012] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0013] Schematic diagram of semiconductor refrigeration figure 1 As shown, the semiconductor refrigeration sheet is based on the Peltier effect, and the heat pump made of semiconductors transfers the heat from the cold end to the hot end, and dissipates the excess heat with heat sinks or heat exchange fans. The picture is a working principle diagram. A P-type semiconductor element and an n-type semiconductor element are connected to form a thermocouple. After connecting to a DC power supply, a temperature difference and heat transfer will occur at the joint. At one junction above, the current direction is n—p, the temperature drops and absorbs heat, which is the cold junction. And at a joint below, the current direction is p-n, the temperature rises and releases heat, so it is a hot end. If a large enough heat sink and cooling device (such as a f...

Abstract

The invention discloses a semiconductor-type vehicle-mounted refrigerator with the adjustable and displayable temperature. The semiconductor-type vehicle-mounted refrigerator with the adjustable and displayable temperature comprises a power module, a temperature control module, a semiconductor heat pump, a thermometer module and an LED display portion. The output end of the power module is connected with the input end of the temperature control module. The output end of the temperature control module is connected with the semiconductor heat pump. The thermometer module converts temperature signals into digital signals and inputs the digital signals to the LED display portion. The semiconductor heat pump is structurally characterized in that the positive pole of a power source is connected with one end of an N-type semiconductor element through a first hot end, the other end of the N-type semiconductor element is connected with one end of a P-type semiconductor element through a cold end, and the other end of the P-type semiconductor element is connected with the negative pole of the power source through a second hot end. The semiconductor-type vehicle-mounted refrigerator with the adjustable and displayable temperature can achieve a refrigeration effect or a heating effect and has the advantages of saving energy, being environment friendly, free of noise, portable and the like, and cost is lower.

Description

technical field [0001] The invention discloses a semiconductor-type temperature-adjustable and displayable vehicle-mounted refrigerator. Background technique [0002] Car refrigerators are the continuation of household refrigerators. The commonly used technical solutions are made by semiconductor electronic refrigeration technology, and some are made by compressor refrigeration technology. Car refrigerators generally require less noise and less pollution. You only need to insert the power plug into the cigarette lighter hole to cool down the refrigerator while driving. At present, the compressor car refrigerator is mainly used in the market. The compressor is the traditional technology of the traditional refrigerator, and the cooling temperature is low. But this kind of refrigerator is heavy in weight, inconvenient to carry, and expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a semiconductor-type tem...
