Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and specifically to refrigeration equipment with a heat preservation structure. Background Technology

[0002] Refrigeration equipment mainly consists of compressors, expansion valves, evaporators, condensers, accessories, and pipelines. According to their working principles, they can be divided into compression refrigeration equipment, absorption refrigeration equipment, steam jet refrigeration equipment, heat pump refrigeration equipment, and electric heating refrigeration devices. With economic development and the continuous improvement of people's living standards, the refrigeration industry has developed rapidly, and the application of refrigeration technology has become increasingly widespread.

[0003] The shells of most existing refrigeration equipment are made of an inner liner, an insulation layer, and an outer shell layer arranged sequentially from the inside out. This insulation structure is relatively simple and has poor insulation effect, which leads to frequent or continuous operation of the compressor, increasing energy consumption. In addition, the compressor is under high load for a long time, which can easily cause overheating, resulting in a shortened lifespan or even premature damage. Therefore, it is necessary to develop a refrigeration equipment with better insulation effect. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figure 1-4As shown, the refrigeration equipment with a thermal insulation structure described in this embodiment includes a housing 1. The housing 1 is composed of a heat-reflective layer 12, a thermal insulation layer 13, and a moisture-proof layer 14. The heat-reflective layer 12 is used to reflect infrared radiation and reduce radiative heat transfer. The thermal insulation layer 13 is used for heat insulation and reduces heat transfer between the inside and outside of the thermal insulation layer 13. The moisture-proof layer 14 is used to prevent water vapor from penetrating into the thermal insulation layer 13. The thermal insulation layer 13 is prone to absorbing moisture, and its thermal conductivity increases after absorbing moisture. The heat-reflective layer 12, the thermal insulation layer 13, and the moisture-proof layer 14 are arranged sequentially from the inside out. The interior of the housing 13 is provided with multiple matrix-distributed negative pressure thin cavities 16, which are used to further block convective heat transfer. The heat reflective layer 12 is aluminum foil, and the insulation layer 13 is polyurethane foam. The refrigeration component is located on the rear side of the housing 1. By setting the heat reflective layer 12, insulation layer 13, negative pressure thin cavities 16 and moisture-proof layer 14, the heat preservation effect of the device is greatly improved, avoiding frequent operation of the compressor 5 due to poor heat preservation effect, effectively reducing the energy consumption of the device, and greatly extending the service life of the device.

[0024] The refrigeration assembly includes a compressor 5, a condenser 7, and an expansion valve 6. The compressor 5, condenser 7, and expansion valve 6 are connected in sequence through pipelines. The inner side of the moisture-proof layer 14 is provided with an inner liner layer 15, and the outer side of the heat-reflective layer 12 is provided with an outer shell layer 11. The inner side of the inner liner layer 15 is provided with an evaporator 4. The evaporator 4 is connected to the compressor 5 and the expansion valve 6 through pipelines respectively.

[0025] The box body 1 has a door 2 on its side, and a sealing magnetic strip 3 is provided on the inside of the door 2.

[0026] Working principle

[0027] When refrigeration is performed, the compressor 5 is started to compress the low-temperature, low-pressure refrigerant gas and outputs the high-temperature, high-pressure gas to the condenser 7. The condenser 7 cools the high-temperature, high-pressure gas into a high-pressure liquid. The high-pressure liquid is throttled and depressurized when it passes through the expansion valve 6, and then enters the evaporator 4. The evaporator 4 causes the refrigerant to absorb heat and evaporate, thereby reducing the temperature inside the casing 1 and completing the refrigeration work.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
