All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not in themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.

The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

in the refrigerating electrical equipment such as an air-cooled refrigerator, cold air is introduced into a refrigerating chamber and a freezing chamber through a refrigerating mechanism formed by a fan, an evaporator and the like, and the temperature in the refrigerating chamber and the freezing chamber is regulated by matching with a flow and temperature detecting mechanism; correspondingly, when the refrigerating chamber receives cold air, the air in the refrigerating chamber is pumped away and conveyed to the refrigerating mechanism, and is conveyed back to the refrigerating chamber after heat exchange and refrigeration, so that the circulating refrigeration in the refrigerating chamber is realized; thereby realizing the temperature control of a plurality of refrigeration chambers of the refrigeration electrical equipment through a set of refrigeration system.

Generally, refrigerating components such as an evaporator of a single system and the like are arranged at the back of a freezing chamber, a freezing air inlet structure and a freezing air return structure can be directly communicated with the freezing chamber at a short distance, and the structure is relatively simple; however, the pipelines for circulating the air inlet and the air return of the refrigerating chamber are arranged in the back heat-insulating foaming layer of the electrical equipment, so that the pipeline structure is bent and complicated, the air return efficiency is affected, the overall thickness of the foaming layer is increased to a certain extent, and the complexity of the overall processing technology is increased.

Therefore, the embodiment of the application provides a refrigerating device which is used for refrigerating electrical equipment such as a refrigerator and the like, and has the effects of improving the structural complexity of the return air pipeline of the refrigerating chamber to a certain extent and reducing the thickness of the back heat-insulating foaming layer of the electrical equipment and the complexity of the processing technology.

Referring to fig. 1 and 2, a refrigeration apparatus provided in an embodiment of the present application includes: the heat exchange flow guide assembly 200 comprises a shell 100 and a return air channel 150 arranged on the shell 100; the shell 100 is provided with an inner cavity 140, the shell 100 is provided with a first air return opening 120 and an air supply opening 110, the inner cavity 140 is communicated with the external environment, and air flow can flow into the inner cavity 140 through the first air return opening 120 and flow out of the air supply opening 110; wherein, the return air channel 150, the first return air inlet 120, the inner cavity 140 and the air supply outlet 110 are sequentially communicated to form an air flow channel passing through the inner cavity 140; the heat exchange flow guiding assembly 200 is arranged in the inner cavity 140 to guide the air flow to flow from the first air return opening 120 to the air supply opening 110, and the passing air flow can exchange heat with the heat exchange flow guiding assembly 200, so that the temperature of the air flow is reduced, and cold air is output to the outside; thus, when the refrigerating apparatus is mounted on the refrigerator, the return air channel is communicated with the refrigerating chamber of the refrigerator, and the air in the refrigerating chamber sequentially passes through the return air channel 150 and the first return air inlet 120, enters the inner cavity 140 to exchange heat with the heat exchange flow guiding assembly 200 for cooling, and then flows back to the refrigerating chamber through the air supply inlet 110.

Compared with the method that an embedded return air pipeline and accessories are bent in a heat insulation layer at the back of the refrigerator, the return air channel 150 is directly arranged on the shell 100, the shell structure of the refrigerating device can be used as a carrier, a channel structure for air movement is formed through regional form design and planning of the shell 100, the complexity of the whole form and structure is simplified to a certain extent, the number of bending sections and the bending amplitude can be reduced as a whole, and the whole length is also reduced relatively, so that the adverse effect on the return air efficiency is weakened as a whole; on the other hand, the return air channel 150 is not pre-buried in the heat preservation foaming layer, so that the overall thickness of the heat preservation foaming layer is reduced to a certain extent, the overall volume rate of the refrigerator can be improved, the process complexity is reduced, and the overall cost can be reduced.

Compared with an external bending pipeline structure, the length of the whole pipeline can be reduced, the area planning and layout on the shell 100 can be utilized, the condition that the pipeline is bent more in the heat preservation foaming layer can be improved, the length of the return air channel 150 can be shortened to a certain extent, the number of bending areas can be reduced, and the influence on the return air efficiency can be reduced.

Referring to fig. 2, 5 and 6, in some embodiments, to match the installation and connection requirements of the field and the refrigerating and freezing chambers, the return air channel 150 needs to be adjusted to a certain extent, that is, there is a certain degree of bending and turning; for this purpose, the communicating grooves may be provided as a first end groove 151, a middle groove 152 and a second end groove 153 which are sequentially communicated, wherein the first end groove 151 is correspondingly adapted to communicate with the refrigerating chamber, the second end groove 153 is adapted to connect with the first return air inlet 120, and the middle groove 152 is respectively in bending communication with the first end groove 151 and the second end groove 152, thereby giving consideration to both the smoothness of the return air channel 150 and the adaptation of the installation position of the installation site.
