The refrigerating equipment provided by the embodiment of the utility model can have various implementation forms, and can be a refrigerator, a freezer, a showcase and the like.

As shown in fig. 1 to 12, in an exemplary embodiment of the refrigerating apparatus of the present utility model, the refrigerating apparatus includes a cabinet having a receiving chamber for receiving an article therein, a door, and a refrigerating system, the receiving chamber having a receiving chamber opening through which the article is placed in the receiving chamber or the article in the receiving chamber is taken out; the box door is positioned at the opening of the accommodating chamber and the box body can be connected in an opening and closing way so as to open or close the accommodating chamber, thereby facilitating the user to take and put articles from the accommodating chamber; the refrigerating system is installed at the box body and used for refrigerating or freezing the articles placed in the accommodating chamber.

In some embodiments, the tank comprises a tank shell and a liner 1, wherein the tank shell is used for forming the whole appearance of the refrigeration equipment, the tank is provided with a top and a bottom, the top of the tank is opposite to the bottom of the tank, and the height direction of the tank is from the top of the tank to the bottom of the tank; the left side of the box body is opposite to the right side of the box body, and the width direction of the box body is from the left side of the box body to the right side of the box body; the front side of the box body and the rear side of the box body are opposite, and the direction from the front side of the box body to the rear side of the box body is the thickness direction of the box body; the inner container 1 is arranged inside the box shell and is jointly limited and shaped with the box shell to form an installation cavity, and the installation cavity is positioned outside the inner container 1 and is used for installing other component structures of the refrigeration equipment and forming a foaming heat-insulating layer; the inner container 1 forms a containing chamber; the box door is arranged on the box shell, and the box door and the box body are rotatably connected through the hinge assembly so as to conveniently open or close the accommodating chamber; part of components of the refrigerating system are arranged in the mounting cavity and used for releasing heat in the refrigerating equipment to the external environment so as to provide cold energy for the accommodating chamber and maintain the low-temperature environment in the accommodating chamber; it should be noted that, the one side of chamber door towards holding the room is equipped with the sealing strip to make the room environment airtight as far as possible, thereby prevent leaking cold, avoid reducing refrigeration equipment's refrigeration effect.

In the prior art, the refrigeration equipment utilizes the principle of refrigerant vaporization heat absorption and liquefaction heat release to perform refrigeration. The liquid condenses and flows through the accommodating chamber to absorb heat in the accommodating chamber and gasify into a gaseous state, so that the ambient temperature of the accommodating chamber is reduced; when the gaseous refrigerant flows out of the accommodating chamber, the gaseous refrigerant is liquefied into liquid and releases heat, and the heat of the accommodating chamber is transferred to the outside of the accommodating chamber by switching the refrigerant between the gaseous state and the liquid state, so that the refrigerating of the accommodating chamber is completed.

In the refrigeration equipment, the refrigeration system comprises a compressor 3, two heat exchangers 2 and other components, wherein one heat exchanger 2 is used as an evaporator, the other heat exchanger 2 is used as a condenser, the compressor 3, the condenser and the evaporator are connected through pipelines, and refrigerant is arranged in the compressor 3, the condenser and the evaporator; the compressor 3 is arranged in the installation cavity, the compressor 3 is used for compressing low-pressure gaseous refrigerant into high-pressure refrigerant, the compressor 3 is provided with an inlet and an outlet, the refrigerant enters the compressor 3 from the inlet of the compressor 3 and then flows out of the compressor 3 from the outlet of the compressor 3, the inlet of the compressor 3 is connected with the evaporator, and the outlet of the compressor 3 is connected with the condenser; the evaporator is arranged outside the accommodating chamber and used for vaporizing the liquid refrigerant to form a gaseous refrigerant; the condenser is used for liquefying the gaseous refrigerant to form a liquid refrigerant; it should be noted that, because the refrigerant can release heat at the condenser, if heat gathers in the installation cavity then can produce adverse effect to the box, consequently, the radiating hole has been seted up to the case shell, and the condenser is close to the radiating hole setting to in time discharge the heat that the gaseous refrigerant liquefaction produced the installation cavity.

In some embodiments, as shown in fig. 1, the compressor 3 is installed in a compressor installation area 11, and the compressor installation area 11 is disposed at the outer circumference of the liner 1 and communicates with the installation cavity; by providing the compressor mounting area 11, the mounting position of the compressor 3 is located.

In the prior art, the heat exchanger 2 comprises a heat exchange pipeline 22, and a refrigerant flows in the heat exchange pipeline 22 to exchange heat with air or the liner 1; in order to increase the heat exchange efficiency of the heat exchange pipeline 22, a heat sink or a winding wire is usually arranged on the outer side of the heat exchange pipeline 22 to increase the heat exchange area of the heat exchange pipeline 22, thereby increasing the heat exchange efficiency; when the heat exchange pipeline 22 exchanges heat, on the one hand, heat is transferred through contact, and on the other hand, heat is transferred through air, so gaps need to be left between adjacent cooling fins or adjacent wires, so that air can be fully contacted with the heat exchange pipeline 22, and heat or cold of the heat exchange pipeline 22 is taken away through air flow. In the prior art, although the mode of winding the metal wire around the periphery of the heat exchange pipeline 22 has good heat exchange effect, the winding efficiency of the metal wire is too low, so that the production efficiency of the heat exchanger 2 is low, and the mass production of refrigeration equipment is not facilitated; therefore, the cooling device is connected with the rib 21 in the heat exchange pipeline 22, so that the rib 21 extends at least along the outer surface of the heat exchange pipeline 22, and the heat exchange area of the heat exchange pipeline 22 is increased by the rib; and the rib 21 is designed as a hollowed-out structure so that air can contact with the heat exchange pipeline 22.

In the above-mentioned refrigerating apparatus, as shown in fig. 3, two opposite sides of the heat exchange pipeline 22 are respectively provided with ribs 21, and two ribs 21 are arranged in parallel with each other and welded with the heat exchange pipeline 22; the rib 21 is a metal sheet with strong heat transfer capability, and the rib 21 is provided with a plurality of grids so that the rib 21 is in a hollowed-out structure; it should be noted that, compared with a wire tube heat exchanger, the mesh of the ribs 21 is formed by punching or cutting, and the metal plate is punched or cut to form the mesh-shaped ribs 21, so that the same heat exchange effect as the heat exchange pipeline 22 is achieved, and the production efficiency is high; it should be further noted that, although the rib 21 is stamped or cut to form a hollow structure in a grid shape, the rib 21 is integrated, and when the rib 21 is locally damaged and broken, the effect of welding other parts of the rib 21 and the box body is little, and the damaged part or broken part can be repaired by locally binding or the like by using a metal wire, which belongs to the common general knowledge technology in the art and is not repeated. In addition, it should be noted that in actual production, if the metal plate is not sized to meet the requirements of the heat exchange tube 22, the two metal plates may be welded together to form a fin.

In some embodiments, the thickness of the metal plate from which the ribs 21 are made is 0.5-2 mm, and the metal plate after cutting out the grids can be elongated 4 times, between 1-2 mm between adjacent grids.

In the prior art, the reserved space for installing the heat exchanger 2 in different refrigeration equipment is different, which leads to the structure of the heat exchange pipeline 22 to be matched with the reserved installation space of the refrigeration equipment, correspondingly, the rib 21 is welded on the outer side of the heat exchange pipeline 22, and the structure of the rib 21 is matched with the structure of the heat exchange pipeline 22. Although the structures of the ribs 21 are different, it is determined that the ribs 21 of different structures are formed by bending or the like of a mesh-like metal plate. The specific structure of the fin 21 welded to the three heat exchange pipes 22 will be described in detail below by taking three heat exchange pipes 22 of different structures as an example.
