[0012] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort also belong to the protection scope of the present application.

[0013] The embodiments of the present application provide an evaporator and a refrigerator, which will be specifically described in combination with the drawings.

[0014] The present application provides a refrigerator, which has a refrigeration system including a compressor, a condenser, an expansion valve and an evaporator, and the components are connected through pipes, and the pipes are provided with refrigerant, and the refrigerant circulates between the components.

[0015] Firstly, the compressor sucks in the refrigerant in the form of low-temperature and low-pressure gas, and then compresses the refrigerant into the form of high-temperature and high-pressure gas. This process needs the compressor to consume electric energy, so that the temperature and pressure of the refrigerant are both increased.

[0016] Then, the high-temperature and high-pressure refrigerant is cooled into high-pressure liquid through the condenser. The condenser is essentially a radiator, which radiates the heat emitted by the high-temperature and high-pressure refrigerant to the surrounding environment, and at the same time, the refrigerant itself is also cooled into high-pressure liquid.

[0017] Then, the refrigerant in the form of low-temperature and high-pressure liquid passes through the expansion valve to form low-temperature and low-pressure gas. The expansion valve is a throttling device, which can reduce the pressure of the low-temperature and high-pressure refrigerant after passing through, so that the temperature and pressure are both decreased to become low-temperature and low-pressure gas.

[0018] Finally, the refrigerant in the form of low-temperature and low-pressure gas absorbs heat to become low-temperature and low-pressure gas when passing through the evaporator. The evaporator is a heat exchanger, which can make the low-temperature and low-pressure gas absorb the heat inside the refrigerator, thereby reducing the temperature inside the refrigerator.

[0019] The refrigeration system can also include a fan, which can promote the flow of cold air around the evaporator, and the refrigeration is carried out in a circulating manner.

[0020] Therefore, the refrigeration system must be started in the process of cooling the target object. For example, when the refrigerator needs to cool the objects in the storage compartment or the freezing compartment, the compressor and the fan of the refrigerator must be started, i.e. the entire refrigeration system must be started to complete the function of cooling the storage compartment or the freezing compartment. This will cause the compressor to be frequently started and stopped.

[0021] The refrigerator provided in the present application has an evaporator with a cold storage function. When the compressor is running and the evaporator is cooling the objects in the storage compartment or the freezing compartment of the refrigerator, the evaporator can also store cold energy. When the compressor is stopped, the cold energy can be released to other objects first, thereby delaying the compressor stop time, avoiding frequent starting and stopping of the compressor, prolonging the service life of the compressor, and reducing energy consumption.

[0022] Please refer to Figure 1 , Figure 1 The structure diagram of the evaporator provided in the embodiments of the present application is shown.

[0023] The evaporator 100 provided in the embodiments of the present application will be described in detail below. The evaporator 100 can store the cold energy of the evaporator 100 pipeline in the cold storage assembly 20, and then release the cold energy through the cold storage assembly 20.

[0024] The evaporator 100 includes an evaporating pipeline 10 and a cold storage assembly 20. The cold storage assembly 20 is attached to the evaporating pipeline 10 and can store part of the cold energy generated by the refrigerant in the evaporator 100 pipeline.

[0025] The evaporating pipeline 10 is provided with refrigerant, which can cool the objects in the storage compartment or the freezing compartment of the refrigerator.

[0026] The cold storage assembly 20 includes a shell and a cold storage agent. The shell has a containing cavity, and the cold storage agent is arranged in the containing cavity. The shell can be made of a heat-conducting material, such as metal, for example, aluminum, which has the advantages of low cost and good heat conduction. The shell can be a tubular structure, such as an aluminum pipe. The tubular structure can improve the utilization rate of the material and is beneficial to preparation and cost saving.

[0027] The cold storage agent can be a phase change material or a chilled carrier. The phase change material has a high melting potential at the phase change temperature, such as polyethylene glycol. The chilled carrier can be a glycol solution.

[0028] In order to increase the cold energy conduction between the evaporating pipeline 10 and the cold storage assembly 20, the evaporator 100 further includes a heat-conducting fixing member connected with the evaporating pipeline 10 and the cold storage assembly 20, respectively.

[0029] In some cases, the heat-conducting fixing member can be a heat-conducting adhesive tape. The working principle of the heat-conducting adhesive tape is to realize the conduction and fixation of heat energy through the heat conduction performance of the heat-conducting material and the adhesion performance of the adhesive material. The heat-conducting material of the heat-conducting adhesive tape is usually composed of a metal filler (such as aluminum, copper or wollastonite, etc.) and an adhesive (such as acrylic acid, etc.). The metal filler of the heat-conducting adhesive tape has high heat conduction performance and can effectively conduct heat energy, while the adhesive can fix the heat-conducting material on the device that needs to conduct heat. When the heat-conducting adhesive tape is attached between the evaporation pipe 10 and the cold storage assembly 20, the heat-conducting material can conduct heat through the heat conduction between solids to transfer the heat energy of the cold storage assembly 20 to the evaporation pipe 10, that is, to achieve the purpose of heat dissipation. At the same time, the adhesive material can ensure that the heat-conducting adhesive tape remains fixed without being deformed and falling off.

[0030] The heat-conducting adhesive tape can be wound around the evaporation pipe 10 and the cold storage assembly 20 to be fixed. In some cases, the heat-conducting adhesive tape can be detached to facilitate replacement of the cold storage assembly 20 or maintenance.

[0031] In other cases, the evaporation pipe 10 and the cold storage assembly 20 are fixedly connected in a welded manner to improve the reliability of the connection between the evaporation pipe 10 and the cold storage assembly 20.

[0032] The evaporation pipe 10 includes a plurality of straight pipes 11 and a plurality of curved pipes 12 that are connected to each other, which is beneficial to improve the heat exchange area. The plurality of straight pipes 11 and the plurality of curved pipes 12 are alternately connected, so that the evaporation pipe 10 forms a structure of winding loops, reduces the occupied space and increases the surface area. The number of cold storage assemblies 20 is a plurality, and each cold storage assembly 20 is attached to a straight pipe 11. It can be understood that the plurality of cold storage assemblies 20 are dispersedly arranged, which can store sufficient cold energy without affecting the original refrigeration effect of the evaporation pipe 10.

[0033] The cold storage assembly 20 further includes a temperature sensor connected with the cold storage assembly 20. The temperature sensor can be used to sense the surface temperature of the cold storage assembly 20, and the temperature sensor is used to transmit the temperature signal of the cold storage assembly 20 to the controller.

[0034] The evaporator 100 can be a finned evaporator, and the evaporator 100 further includes a plurality of fins 30 arranged side by side, and the evaporation pipe 10 and the cold storage assembly 20 are jointly arranged in the fins 30. Whether the refrigerant in the evaporator 100 pipe is refrigerated or the cold storage assembly 20 is cooled, the design of the fins 30 can increase the heat exchange area and improve the heat exchange efficiency, so that the evaporator 100 can be quickly cooled, thereby improving the energy storage efficiency and the refrigeration efficiency of the refrigerator.

[0035] The evaporator 100 further comprises a bracket 40 connected with the evaporating assembly. The bracket 40 is used to fix the evaporator 100 to other structures in the refrigerator, so as to improve the reliability of the internal structure of the refrigerator.

[0036] In the evaporator 100 provided by the embodiments of the present application, the evaporator 100 comprises an evaporating pipeline 10 and a cold storage assembly 20 attached to the evaporating pipeline 10. The cold storage assembly 20 comprises a shell and a cold storage agent. The shell has a containing cavity, and the cold storage agent is arranged in the containing cavity. The cold storage assembly 20 can be used to store and release cold energy. When the compressor is running, the cold energy can be stored in the cold storage assembly 20. When the compressor is stopped, the cold energy can be released to other objects through the cold storage assembly 20, so as to delay the stop time of the compressor, avoid frequent start and stop of the compressor, prolong the service life of the compressor and reduce energy consumption.
