Description

Electronic refrigerator

Technical field the utility model relates to a kind of electronic refrigerator, especially relates to a kind of portable electronic refrigerator of using semiconductor refrigerating.

Background technology in the prior art, refrigerator mostly adopts chlorofluoromethane refrigerant to freeze by compressor refrigeration system, employed chlorofluoromethane refrigerant can destroy atmospheric ozone layer, is unfavorable for environmental protection, and refrigerant system configurations complexity, noise are big; The patent No. is that the disclosed electronic refrigerator of the patented technology of ZL98231598.8 belongs to the indoor large refrigerator, has hot and cold water tank and hot and cold water pump, and its structure is comparatively complicated, is not suitable for making the portable electronic refrigerator.

The summary of the invention the purpose of this utility model is to provide a kind of atmosphere pollution simple in structure, no, noiselessness and is portable type and automobile-used electronic refrigerator.

In order to achieve the above object, the utility model provides following technical scheme: design a kind of electronic refrigerator, comprise casing (6), terminal plate (8), Qianmen (2), refrigerating chamber (5) and semiconductor refrigerating and heat assembly (10), semiconductor refrigerating and heat assembly (10) and be tabular, at semiconductor refrigerating with heat between two of assembly (10) exhausted electric heat-conducting plates and have a plurality of P-type semiconductors, N-type semiconductor, two lead-in wires that connect semiconductor element are that the both positive and negative polarity of 12V～24V dc source links to each other with voltage respectively, this semiconductor refrigerating is fixedly connected with the block cold aluminum component (9) that passes with the huyashi-chuuka (cold chinese-style noodles) that heats assembly (10), a side that passes cold aluminum component (9) is fixed with chilled air fan (14), pass cold aluminum component (9) with the vertical direction of chilled air fan (14) face on gas channel (17) is arranged, the outside that passes cold aluminum component (9) and refrigerating chamber (5) bottom is fixedlys connected, semiconductor refrigerating and heat the hot side of assembly (10) and the heat sink of radiator (11) fits, the top of radiator (11) has sending out the hot fan (12), and sending out the hot fan (12) links to each other with heat sink (15) by fin (16) gap that screw passes radiator (11).

In implementing process of the present utility model, semiconductor refrigerating and heat assembly (10) and adopt existing product, passing cold aluminum component (9) can be different shape, when selecting its shape, can consider its area of dissipation big as far as possible and with the vertical direction of chilled air fan (14) face on gas channel (17) is arranged, promote the cold air forced circulation by chilled air fan (14), effectively utilize refrigerating capacity, make 5 faces of refrigerating chamber (5) all can obtain cold and realize effective cooling; By 12V～24C direct current, make cooling assembly workpiece cold reach refrigerating chamber (5) to cold and carry out freezingly by passing cold aluminum component (9), heat has good refrigerating effect discharging by radiator (11) and sending out the hot fan (12).

Compared with prior art, the utlity model has following tangible advantage: 1, the utility model mainly by semiconductor refrigerating and heat assembly (10), pass cold aluminum component (9), chilled air fan (14), radiator (11) and sending out the hot fan (12) constitute its simple and compact structure; 2, because of having used the semiconductor subassembly refrigeration, avoided use fluorine Lyons to make refrigerant, noiselessness not only, also non-environmental-pollution is a kind of Green Product; 3, because its simple and compact structure, use 12V～24V power supply again, thereby volume is little, be particularly suitable for making portable, can be used on the vehicles instrument such as automobile, carry when also being suitable for travelling, thereby the scope of application is wide.
