Double-refrigeration vehicle-mounted refrigerator

Technical Field

The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a double-refrigeration vehicle-mounted refrigerator.

Background

With the continuous expansion of the application range of the vehicle-mounted refrigerator, the application volume of the vehicle-mounted refrigerator is also continuously increased. Semiconductor electronic refrigerators have been gradually widely used in the field of vehicles due to their excellent manufacturing costs. In the application of the vehicle-mounted refrigerator with smaller volume such as less than 4L, a single refrigeration unit basically can meet the use requirement, but for the vehicle-mounted refrigerator with more than 4L, if a single electronic refrigeration unit is used, the single electronic refrigeration unit cannot be realized due to low efficiency, because the volume of the refrigerator is increased, the number of carriers is increased, the energy required for reducing the same temperature is increased, the volume and the projection area of the inner container of the refrigerator are increased, and the unidirectional contact type conduction refrigeration needs longer refrigeration time to meet the use requirement due to the increase of the propagation path.

In order to solve the above problems, a utility model patent entitled "a double-refrigeration vehicular refrigerator" (grant publication number: CN211476423U) discloses the following technical solutions: the refrigeration device comprises a shell, wherein a storage basket is arranged in the shell, a first refrigeration assembly and a second refrigeration assembly are arranged behind the storage basket in the shell, the first refrigeration assembly is composed of a compressor and a condenser, and the second refrigeration assembly is a semiconductor refrigerator. In the scheme, the first refrigerating assembly and the second refrigerating assembly are arranged in the shell behind the storage basket, so that the conduction efficiency is low, and the use requirement can be met only by long refrigerating/heating time; in addition, the first refrigerating assembly consists of a compressor and a condenser and has the defects of high power consumption, high noise and incapability of transiting and inclining in use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a double-refrigeration vehicle-mounted refrigerator which is high in conduction efficiency, low in noise and high in stability.

In order to achieve the purpose, the utility model adopts the technical scheme that: a double-refrigeration vehicle-mounted refrigerator comprises a refrigerator shell, wherein an opening at the upper end of the refrigerator shell is connected with a refrigerator door in an opening and closing mode, an inner container is arranged in a cavity formed by the refrigerator shell and the refrigerator door, and a group of semiconductor refrigeration units are arranged at two sides of the refrigerator shell respectively.

Among the above-mentioned scheme, two refrigeration units are placed respectively in the refrigerator both sides, and heat-conduction efficiency is high, only needs shorter refrigerating time just to reach the operation requirement, and two refrigeration units all adopt the semiconductor refrigeration mode moreover, have advantages such as environmental protection pollution-free, small, with low costs, during operation vibrationless noise and longe-lived.

Detailed Description

As shown in fig. 1 and 2, the double-refrigeration vehicle-mounted refrigerator comprises a refrigerator shell 10, a refrigerator door 20 is connected to an open-close type of an upper end of the refrigerator shell 10, an inner container 30 is arranged in a chamber formed by the refrigerator shell 10 and the refrigerator door 20, and a group of semiconductor refrigeration units 40 is respectively arranged at two sides of the refrigerator shell 10. The double refrigeration units are respectively arranged on two sides of the refrigerator, the heat conduction efficiency is high, the use requirement can be met only by short refrigeration time, and the semiconductor refrigeration unit 40 is adopted by the two refrigeration units, so that the refrigerator has the advantages of environmental protection, no pollution, small volume, low cost, no vibration noise during working, long service life and the like.

The concrete structure is as follows: the semiconductor refrigeration unit 40 comprises a radiating pipe 41 fixed on the outer wall of the refrigerator shell 10 and a semiconductor refrigeration sheet 42 arranged in a cavity between the refrigerator shell 10 and the inner container 30, wherein a cold guide sheet 43 is fixed at the inner end of the semiconductor refrigeration sheet 42, and the cold guide sheet 43 is attached to the outer wall of the inner container 30. The cold surface of the semiconductor refrigeration sheet 42 refrigerates and is transferred to the inner container 30 through the cold conduction sheet, thereby refrigerating the food in the inner container 30.

The cooling tube 41 be square tubulose, the interval is provided with a plurality of fin 411 in the inner chamber of square pipe, still be provided with mounting panel 11 on the refrigerator casing 10 outer wall of the top of cooling tube 41, be fixed with the control unit 50 on the lower face of mounting panel 11, the work that the control unit 50 control corresponds semiconductor refrigeration unit 40, two control unit 50 are parallel connection control system, but simultaneous cooling/heating also exclusive use, two sets of cooling system, independent ventilation, each other noninterference, the performance is more stable.

Preferably, the semiconductor cooling units 40 are disposed at both left and right sides of the refrigerator case 10 and are symmetrically arranged, which is the most desirable position and the highest conduction efficiency.

The heat dissipation pipe 41 is arranged in a horizontal direction, and one end of the heat dissipation pipe 41 is connected with a fan, and the other end is open. The fan draws air to take heat away through the radiating pipe 41 and blows the air out from the other side to assist the semiconductor refrigeration sheet 42 to dissipate heat in the process of refrigeration.
