Embodiment 1

[0029] Such as Figure 1-2 As shown, this embodiment provides a refrigeration device, including a refrigeration unit 2 and a cooling transmission part 1. The cooling transmission part 1 includes a communication pipe 11 containing refrigerant and an energy storage device coated on the outer surface of the communication pipe 11. The refrigerant can circulate in the refrigeration unit 2 and the connecting pipe 11; the energy storage device includes a sleeve 12 arranged on the outer surface of the connecting pipe 11, and a closed space is formed between the inner surface of the sleeve 12 and the outer surface of the connecting pipe 11 , the closed space is filled with energy storage liquid; the energy storage device can absorb and store the cold energy released by the refrigerant.

[0030] In order to improve the cold storage capacity of the energy storage device, the energy storage liquid is water, oil, or phase change cold storage agent and other materials with large phase chang...

Embodiment 2

[0038] Such as image 3 As shown, the difference between the refrigeration device provided in this embodiment and Embodiment 1 is that a partition device is provided between the sleeve pipe 12 and the connecting pipe 11, and the closed space is divided into multiple sections by the partition device, so that the partition The closed spaces on both sides of the blocking device can be filled with different types of energy storage fluids, and the specific blocking device can be a blocking sheet.

Embodiment 3

[0040] Such as Figure 4-5 As shown, this embodiment provides a refrigerated transport box, including a box body and the refrigeration device in Embodiment 1 or Embodiment 2, and the energy storage device can perform heat exchange with the internal storage space of the box body.

[0041] The refrigerating unit 2 used in the refrigerated transport box can use a micro compressor; the basic composition of the micro compressor is composed of rolling pistons, cylinder blocks, petals and springs on their backs, eccentric wheel shafts, and cylinder end caps. Both the cylinder and the rolling piston are circular, and the cylinder body is provided with suction and exhaust ports. A reed exhaust valve is housed above the exhaust port, and an eccentric wheel shaft with a heart turn is installed in the cylinder, which is the main shaft of the refrigeration unit 2. The rotation center of the eccentric wheel shaft coincides with the center of the inner hole of the cylinder, and the rolling ...

Abstract

The invention provides a refrigerating device and a refrigeration and transportation box provided with the same and relates to the field of refrigeration device. The technical problem is solved that arefrigeration unit existing the prior art possibly causes inaccurate temperature control of a refrigeration chamber in the refrigeration process. The refrigeration device comprises a refrigeration unit and a cold energy transmission portion, wherein the cold energy transmission portion comprises a communicating pipe for containing a refrigerant and an energy storing device coating the outer surface of the communicating pipe, the refrigerant can flow in the refrigeration unit and the communicating pipe, the energy storing device comprises a sleeve arranged on the outer surface of the communicating pipe, an airtight space is formed between the inner surface of the sleeve and the outer surface of the communicating pipe and is filled with energy storage liquid, and the energy storing device can absorb and store the cold energy released by the refrigerant. By utilizing the refrigerating device, an appropriate refrigerating environment can be provided for a refrigerator or a refrigeration box more accurately.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration device and a refrigerated transport box with the same. Background technique [0002] Traditional refrigerator evaporators generally use evaporating copper tubes or aluminum tubes around the inner tank shell or the overall inflation plate or air-cooled radiator mode, relying on the direct evaporation of refrigerant for cooling; this method will have certain disadvantages when applied to the field of transport boxes. For example, for medical refrigerators, if the temperature in the box requires accurate temperature control at 2-8°C, the evaporation temperature of the evaporator is too low, and it should be operated at around -20°C (freezing condition), due to the difference between the evaporation temperature and the working temperature in the box If the temperature difference is too large, it is easy to cause the temperature in the refrigerator to be lower th...
