The utility model can be used in vehicle to keep the food, the beverage, the medicine and the vaccine in cold condition in transportation conveniently and reliably with no pollution and high efficiency, and is suitably used in transportation, traveling, medical science, agricultural industry and fishery.
Description
The utility model is the mounted refrigerating case of semiconductor refrigerating.
China utility model patent ZL93223270.1 disclosed " small semiconductor refrigerator " and ZL94238707.4 disclosed " the vehicle-mounted semiconductor freezer of electronics " and ZL93212308.2 " conductor refrigeration vaccine case " and ZL93231041.9 " thermoelectric cold and heat case " include casing, case lid and refrigeration unit, refrigeration unit is by the semiconductor refrigerating module, constitute with the cold side heat exchanger and the hot side heat exchanger of semiconductor refrigerating module cold side and hot side difference close-coupled, all embody semiconductor refrigerating and need not complicated mechanical running structure, do not needed cold-producing medium, pollution-free, characteristics such as volume is little.But their common technological means be with refrigeration unit design in the bottom or the bottom of refrigeration case, this has just limited speed that operating temperature reduces and to the cooling effectiveness of chilled goods, has greatly influenced the performance of refrigeration case.
The purpose of this utility model is to improve the efficient of refrigeration case, improves its refrigeration performance, for it opens up application prospect widely.
The utility model of realizing above-mentioned purpose is a kind of circulating semiconductor refrigerating case, comprise casing, case lid and refrigeration unit, refrigeration unit is by the semiconductor refrigerating module, cold side heat exchanger with semiconductor refrigerating module cold side close-coupled, constitute with the hot side heat exchanger of the hot side close-coupled of semiconductor refrigerating module, it is characterized in that described refrigeration unit places in the case lid, the semiconductor refrigerating module is fixed through being fixed in the case lid sidewall and case lid being divided into two-layer heat-barrier material, fuse with case lid, hot side heat exchanger is towards the case lid outer surface, the cold side heat exchanger is the side box body direction in case lid, the corresponding hot side heat exchanger of case lid outer surface position has hot-blast outlet, and case lid outer surface and hot-blast outlet symmetry position lid have the heat radiation fresh air inlet.
For improving refrigerating efficiency, semiconductor refrigerating case of the present utility model, with cold side heat exchanger position symmetry place air-cooler can be housed on the described case lid inner thermal insulator, there is a lower surface the case lid inboard, described heat-barrier material and refrigeration unit are encapsulated in the case lid, the corresponding air-cooler of lower surface position has the refrigeration fresh air inlet, and corresponding cold side heat exchanger position has the cold wind outlet.
For further improving heat exchanger effectiveness, semiconductor refrigerating case of the present utility model can be installed cooling fan with hot side heat exchanger position symmetry place on described case lid inner thermal insulator, and case lid outer surface heat radiation fresh air inlet position is corresponding with the cooling fan position.
When adopting air-cooler and air-heater simultaneously, two blower fans can be respectively with two fans independently, also can be the fan of same armature coaxial type.
Described hot side heat exchanger and cold side heat exchanger can be rectangular duct, and the thermofin that links the bottom surface is arranged in the air channel.Described hot side heat exchanger and cold side heat exchanger also can be the semi-open type air channel: the bottom surface connects with the semiconductor refrigerating module, is metal plate, and dull and stereotyped opposite side is the thermofin perpendicular to flat board.
Under the situation that does not need to freeze, semiconductor refrigerating case of the present utility model can take off the case lid of band refrigeration unit, and puts a standby common heat-insulation and heat-preservation case lid, uses as general refrigerating box or the incubator with low-temperature receiver not.
Because the utility model is with the top of semiconductor refrigerating unit design apparatus at whole refrigeration case, be on the case lid, thereby cold airflow is big or forced by air-cooler to send cold wind owing to autologous density, thermal current in the casing rises naturally or is sucked from the refrigeration fresh air inlet by air-cooler, cause the interior air-flow of case to circulate, greatly improved the temperature inside the box fall off rate and, also guaranteed the uniformity and the uniformity of each position temperature in the casing simultaneously by the cooling effectiveness of chilled goods.Compare with the scheme of semiconductor refrigerating unit design and installation in the refrigeration case lower part box, when the utility model is blown without air-cooler, only cause free convection in the case, just obtain the temperature inside the box fall off rate and improved 2-4 remarkable result doubly by the chilled goods cooling effectiveness because cold air descends from the top.Simultaneously, since cooling assembly all concentrate on become on the case lid one can be for convenience detach independent sector, therefore on structure and application performance, the utlity model has more flexible purposes widely, be suitable for being placed on the automobile, using automobile power source, for Refrigerated Transport usefulness such as food, beverage, medicine and vaccines, is a kind of product that makes things convenient for of serving traffic, tourism, medicine and farming, animal husbandry and fishery.
