[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] It should be noted that the different features in the embodiments of the present application can be combined with each other without conflict.

[0041] The inventor found that when the main control board box is arranged inside the refrigeration equipment, the main control board box can be installed in the compressor compartment. However, there are components with large heat generation such as compressors and heat exchange pipelines in the compressor compartment, and the main control board will generate a certain amount of heat when working. If the heat dissipation is poor, the main control board may overheat, causing the components of the main control board to accelerate aging or damage, thereby affecting the stability of the equipment operation.

[0042] Therefore, the present embodiment provides a solution to solve the above problems, which will be described in detail below.

[0043] Please refer to Figure 1 , Figure 1An example structure of a refrigeration equipment main control board box provided by the present embodiment is shown in the accompanying drawings. The refrigeration equipment main control board box can include a box body 100, a box cover 300, a heat dissipation plate 400, and a heat exchange pipe 500.

[0044] The box body 100 can be used to accommodate a main control board 200 of a refrigeration equipment. The main control board 200 can be used to control a compressor or other electrical devices of the refrigeration equipment, thereby controlling the refrigeration equipment to work. The box body 100 can have a hollow structure of a cuboid.

[0045] It should be noted that the size and shape of the box body 100 can be designed according to the size and shape of the main control board 200, as long as the main control board 200 can be stably installed in the main control board box. Therefore, the specific design is not limited herein.

[0046] The box cover 300 can be arranged on the box body 100. The box cover 300 can cover the box body 100 to form a relatively closed cavity, so as to protect the main control board 200 in the box body 100, prevent foreign matters from entering the inside of the box body 100, and avoid the main control board 200 from being impacted by external force, thereby enabling the main control board 200 to be stably installed in the main control board box.

[0047] Specifically, the box body 100 and the box cover 300 have good sealing performance, which can be achieved by using sealing rubber strips, buckles, or the like. In addition, the opening and closing mode of the box cover 300 can be designed according to actual needs to ensure convenient operation, so as to facilitate the maintenance and repair of the main control board 200.

[0048] The heat dissipation plate 400 can be arranged on at least one surface of the outside of the box body 100. The heat dissipation plate 400 can be used to dissipate heat of the box body 100.

[0049] Specifically, the heat dissipation plate 400 can completely cover one or more surfaces of the outside of the box body 100. For example, please refer to Figure 1 When the heat dissipation plate 400 covers only one surface of the outside of the box body 100, the heat dissipation plate 400 can be arranged on the bottom surface of the box body 100 opposite to the box cover 300. Please refer to Figure 2 When the heat dissipation plate 400 covers multiple surfaces of the outside of the box body 100, the heat dissipation plate 400 can be arranged on the bottom surface of the box body 100 opposite to the box cover 300 and the side surface between the box cover 300 and the bottom surface. Compared with arranging the heat dissipation plate 400 on only one surface of the box body 100, this method can increase the heat dissipation area and improve the heat dissipation efficiency.

[0050] Please refer to Figure 3 The heat exchange pipe 500 is in contact with the heat dissipation plate 400 and is arranged in a meandering manner. The heat exchange pipe 500 can be used to connect with a cooling pipeline of the refrigeration equipment.

[0051] In the embodiment, during the refrigeration process of the refrigeration device, the cooling liquid of the refrigeration device can be transmitted from the evaporator to the heat exchange pipe 500 through the cooling pipeline, and the cooling liquid flows in the heat exchange pipe 500, exchanges heat with the heat dissipation plate 400, carries away the heat on the heat dissipation plate 400, and is finally transmitted to the compressor, so that the temperature of the main control board 200 in the main control board box can be further reduced. In addition, the purpose of the winding arrangement of the heat exchange pipe 500 is to increase the contact area of the heat exchange pipe 500 and the heat dissipation plate 400, improve the heat exchange efficiency, and facilitate the cooling liquid in the heat exchange pipe 500 to carry away the heat of the heat dissipation plate 400 more quickly.

[0052] It should be noted that the heat exchange pipe 500 can be an additional independent pipeline connected with the cooling pipeline, or can be a part of the cooling pipeline, as long as the heat exchange pipe 500 is in contact with the heat dissipation plate 400 and can exchange heat with the heat dissipation plate 400.

[0053] In the above structure, by arranging the heat dissipation plate 400 on at least one surface of the box body 100, the heat of the box body 100 can be effectively conducted to the outside, and at the same time, by arranging the heat exchange pipe 500 in contact with the heat dissipation plate 400, the heat can be carried away by the flow of the cooling liquid in the heat exchange pipe 500, and the temperature of the main control board 200 is further reduced to ensure stable operation. In this way, not only the heat dissipation efficiency can be improved, but also the service life of the refrigeration device can be prolonged, and the overall refrigeration effect is optimized.

[0054] In a possible implementation, the orthographic projection of the heat exchange pipe 500 on the box body 100 at least partially overlaps the orthographic projection of the main control board 200 on the box body 100. The density of the winding distribution of the heat exchange pipe 500 in at least part of the region can be greater than the density of the winding distribution of the heat exchange pipe 500 in another at least part of the region. The winding distribution density of the heat exchange pipe 500 refers to the arrangement length or quantity of the heat exchange pipe 500 per unit area. The greater the winding distribution density of the heat exchange pipe 500 means that the length of the heat exchange pipe 500 or the number thereof is greater in the same area.

[0055] In the embodiment, the main control board 200 generates heat during operation, and when the orthographic projection of the heat exchange pipe 500 on the box body 100 at least partially overlaps the orthographic projection of the main control board 200 on the box body 100, the heat generated by the main control board 200 can be more directly transmitted to the heat exchange pipe 500 corresponding to the position, and the heat is carried away by the flow of the cooling liquid in the heat exchange pipe 500, thereby improving the heat dissipation efficiency.

[0056] In addition, since the heat generated by different electronic devices on the main control board 200 is different, for the area with large heat generation on the main control board 200, the density of the serpentine distribution of the heat exchange pipe 500 corresponding to the area can be increased, so that in the area with large heat generation, the contact area of the heat exchange pipe 500 and the heat dissipation plate 400 is also large, and the heat dissipation effect of the area with large heat generation can be improved.

[0057] In some examples, some core processor chips, high-power drive circuits and other elements in the main control board 200 will generate a large amount of heat when working, and some auxiliary circuits, signal transmission lines and other elements have relatively small heat generation, therefore, when the heat exchange pipe 500 is arranged, the density of the serpentine distribution of the heat exchange pipe 500 in the area where the elements with large heat generation are located can be increased, and the density of the serpentine distribution of the heat exchange pipe 500 in the area where the elements with small heat generation are located can be reduced.

[0058] In a possible implementation, the main control board 200 can include a first area and a second area, the heat generation of the first area can be greater than the heat generation of the second area, the heat exchange pipe 500 can include a third area 610 and a fourth area 620, the density of the serpentine distribution of the heat exchange pipe 500 in the third area 610 can be greater than the density of the serpentine distribution of the heat exchange pipe 500 in the fourth area 620, the orthographic projection of the first area on the surface of the box body 100 and the orthographic projection of the third area 610 on the surface of the box body 100 at least partially coincide, and the orthographic projection of the second area on the surface of the box body 100 and the orthographic projection of the fourth area 620 on the surface of the box body 100 at least partially coincide.

[0059] In a possible implementation, please refer to Figure 4 , the main control board 200 can include a first area and a second area with different heat generation, the heat exchange pipe 500 can include a third area 610 and a fourth area 620 with different densities of serpentine distribution, for the first area with large heat generation, the density of the serpentine distribution of the heat exchange pipe 500 in the third area 610 corresponding to the first area can be increased, and for the second area with small heat generation, the density of the serpentine distribution of the heat exchange pipe 500 in the fourth area 620 corresponding to the second area can be reduced. For example, if the areas of the third area 610 and the fourth area 620 are the same, the length of the heat exchange pipe 500 in the third area 610 can be greater than the length of the heat exchange pipe 500 in the fourth area 620, or the number of heat exchange pipes 500 in the third area 610 can be greater than the number of heat exchange pipes 500 in the fourth area 620, so as to ensure efficient heat transfer.

[0060] Specifically, the area of the third region 610 of the heat exchange pipe 500 can be different from the area of the fourth region 620 of the heat exchange pipe 500, the area of the third region 610 of the heat exchange pipe 500 is determined by the area of the first region of the main control board 200, and the area of the fourth region 620 of the heat exchange pipe 500 is determined by the area of the second region of the main control board 200. The third region 610 of the heat exchange pipe 500 and the fourth region 620 of the heat exchange pipe 500 are not necessarily two adjacent regions, the position of the third region 610 of the heat exchange pipe 500 is determined by the position of the first region of the main control board 200, and the position of the fourth region 620 of the heat exchange pipe 500 is determined by the position of the second region of the main control board 200. For example, the first region can be located at the edge position of the main control board 200, and the second region can be located at the center position of the main control board 200.

[0061] In addition, the density of the meandering distribution of the heat exchange pipe 500 can be determined according to the actual heat generation of the main control board 200, the greater the heat generation, the greater the density of the meandering distribution of the heat exchange pipe 500.

[0062] In another possible implementation, please refer to Figure 5 The cross-sectional area of the heat exchange pipe 500 can also be adjusted to improve the heat dissipation effect of the region with larger heat generation. When the main control board 200 includes a first region and a second region with different heat generations, and the heat exchange pipe 500 includes a third region 610 and a fourth region 620, for the first region with larger heat generation, the cross-sectional area of the heat exchange pipe 500 corresponding to the third region 610 of the first region can be increased, and for the second region with smaller heat generation, the cross-sectional area of the heat exchange pipe 500 corresponding to the fourth region 620 of the second region can be reduced.

[0063] It should be noted that the main control board 200 is not limited to the first region and the second region, and can also include other regions with different heat generations from the first region and the second region, for example, a fifth region. The heat generation of the fifth region can be greater than that of the second region, and the heat generation of the fifth region can be less than that of the second region. The heat exchange pipe 500 is not limited to the third region 610 and the fourth region 620, and can also include other regions, for example, a sixth region. The sixth region of the heat exchange pipe 500 can correspond to the fifth region of the main control board 200, the density of the meandering distribution of the heat exchange pipe 500 in the sixth region can be greater than that in the fourth region, and the density of the meandering distribution of the heat exchange pipe 500 in the sixth region can be less than that in the third region.

[0064] In the above structure, by setting the density of the meandering distribution of the heat exchange pipe 500 corresponding to the region with large heat generation to be greater than the density of the meandering distribution of the heat exchange pipe 500 corresponding to the region with small heat generation, not only can the allocation of heat dissipation resources be optimized, but also the overall heat dissipation efficiency can be improved, so as to ensure that the main control board 200 works in a suitable temperature range.

[0065] In a possible implementation, please refer to Figure 1 , the heat exchange pipe 500 can be located on the surface of the heat dissipation plate 400 away from the box body 100, and the cross-sectional shape of the heat exchange pipe 500 can include a D type, and the side of the heat exchange pipe 500 close to the heat dissipation plate 400 is flat and adheres to the heat dissipation plate 400.

[0066] In this embodiment, the heat generated by the main control board 200 during work is first transmitted to the box body 100, and then transmitted to the heat dissipation plate 400 by the box body 100. By setting the heat exchange pipe 500 on the side of the heat dissipation plate 400 away from the box body 100, the heat exchange pipe 500 can more directly exchange heat with the heat dissipation plate 400, avoiding excessive accumulation of heat on the heat dissipation plate 400, thereby improving the overall heat dissipation efficiency. In addition, by setting the heat exchange pipe 500 on the side of the heat dissipation plate 400 away from the box body 100, it is not necessary to perform complicated installation work in the space between the box body 100 and the heat dissipation plate 400, which facilitates subsequent disassembly and maintenance.

[0067] Specifically, when the heat exchange pipe 500 can be an additional independent pipe connected with the cooling pipe, the heat exchange pipe 500 can be a D type pipe, and the heat exchange pipe 500 and the heat dissipation plate 400 can be connected together by welding or gluing, so that the heat exchange pipe 500 and the heat dissipation plate 400 are closely adhered. When the heat exchange pipe 500 is part of the cooling pipe, the cooling pipe in contact with the heat dissipation plate 400 can be extruded to form a D type cross section, so as to ensure full contact with the heat dissipation plate 400 and enhance the heat dissipation effect.

[0068] In the above structure, compared with the heat exchange pipe 500 with a circular cross-sectional shape, by setting the cross-sectional shape of the heat exchange pipe 500 to be a D type, the side of the heat exchange pipe 500 close to the heat dissipation plate 400 is flat and adheres to the heat dissipation plate 400, which can increase the contact area between the heat exchange pipe 500 and the heat dissipation plate 400, facilitate the transmission of more heat from the heat dissipation plate 400 to the cooling liquid in the heat exchange pipe 500, and be conducive to improving the heat dissipation efficiency.

[0069] It should be noted that the cross-sectional shape of the heat exchange pipe 500 is not limited to a D type, but can also be a rectangle, a triangle, etc., as long as the side of the heat exchange pipe 500 close to the heat dissipation plate 400 is flat and adheres to the heat dissipation plate 400, which is not limited here.

[0070] In a possible implementation, please refer to Figure 6a andFigure 6b The refrigeration equipment main control board box can further include a plurality of fixing members 700, which can be used to fix the heat exchange pipe 500 on the surface of the heat dissipation plate 400, so as to avoid the heat exchange pipe 500 from being separated from or having a gap with the heat dissipation plate 400 due to vibration, shaking or other reasons during the operation of the equipment, improve the reliability and stability of the refrigeration equipment main control board box, and reduce the maintenance cost.

[0071] In this embodiment, the plurality of fixing members 700 can be installed on the surface of the heat dissipation plate 400 by welding, gluing or mechanical connection, etc. The fixing member 700 can be used to fix the heat exchange pipe 500 at a predetermined position, so that the plane of the side of the heat exchange pipe 500 close to the heat dissipation plate 400 is tightly attached to the heat dissipation plate 400, avoiding displacement of the heat exchange pipe 500, thereby improving the heat dissipation efficiency, enabling the main control board 200 to work stably in a suitable temperature environment, and prolonging its service life.

[0072] It should be noted that the shape and number of the fixing member 700 can be adjusted according to actual needs to ensure that the attachment effect between the heat exchange pipe 500 and the heat dissipation plate 400 is optimal, thereby further improving the heat dissipation efficiency. The material selection of the fixing member 700 should also consider the thermal conductivity to reduce the loss in the heat transfer process.

[0073] Exemplarily, the fixing member 700 can be a fixed hook, and the heat exchange pipe 500 can pass through the plurality of fixed hooks in sequence.

[0074] In another possible implementation, the plurality of fixing members 700 can be arranged on the surface of the box body 100, and the fixing member 700 and the box body 100 can be an integrally formed structure.

[0075] In a possible implementation, please refer to Figure 7 The heat dissipation plate 400 is a hollow structure provided with a pipe fixing groove 410, and the heat exchange pipe 500 can extend in the pipe fixing groove 410 of the heat dissipation plate 400.

[0076] In this embodiment, the heat dissipation plate 400 can be provided with a pipe fixing groove 410, and the pipe fixing groove 410 is distributed in a meandering manner. The heat exchange pipe 500 can be located in the pipe fixing groove 410, and the heat exchange pipe 500 can be tightly connected with the heat dissipation plate 400 through the pipe fixing groove 410, ensuring efficient heat transfer.

[0077] In addition, the thickness of the heat dissipation plate 400 can be greater than the diameter of the heat exchange pipe 500, and the cross-sectional shape of the pipe fixing groove 410 can be the same as that of the heat exchange pipe 500 to achieve better attachment effect.

[0078] In the above structure, by fixing the heat exchange pipe 500 in the pipe fixing groove 410 of the heat dissipation plate 400, displacement of the heat exchange pipe 500 due to vibration, shaking and the like during operation of the equipment can be prevented, and the heat exchange pipe 500 and the heat dissipation plate 400 can be ensured to always be closely attached, increasing the contact area between the heat exchange pipe 500 and the heat dissipation plate 400, thereby timely reducing the temperature of the heat dissipation plate 400. In addition, by fixing the heat exchange pipe 500 in the pipe fixing groove 410 of the heat dissipation plate 400, the volume can also be effectively saved.

[0079] In a possible implementation, please refer to Figure 8 The heat dissipation plate 400 can be connected with the box body 100 by the adhesive 800. Specifically, the adhesive 800 has high thermal conductivity and high temperature resistance, so as to ensure firm connection and high heat conduction efficiency between the heat dissipation plate 400 and the box body 100.

[0080] It should be noted that the heat dissipation plate 400 and the box body 100 are not limited to be connected by the adhesive 800, but can also be mechanically fixed by a buckle or the like, so that the heat dissipation plate 400 is embedded on the surface of the box body 100. The connection mode of the heat dissipation plate 400 and the box body 100 can be adjusted according to actual needs, which is not specifically limited here.

[0081] In a possible implementation, the material of the heat dissipation plate 400 can include metal, and the material of the heat dissipation plate 400 is preferably copper.

[0082] In the embodiment, the metal copper has excellent thermal conductivity, can quickly transfer the heat of the box body 100 to the surface of the heat dissipation plate 400, and then the heat exchange pipe 500 can take away the heat, so as to effectively reduce the temperature of the main control board 200 and improve the overall heat dissipation effect. In addition, the metal copper has strong corrosion resistance and can resist the corrosion of external air, moisture and some chemical substances, so that the heat dissipation plate 400 will not be affected in heat dissipation performance and structural strength due to corrosion in a long-term use process, prolonging the service life of the heat dissipation plate 400, reducing the maintenance and replacement cost caused by corrosion, thereby ensuring the stability and reliability of the equipment operation.

[0083] In a possible implementation, the material of the box body 100 can include Acrylonitrile Butadiene Styrene (ABS) or Polypropylene (PP).

[0084] In the embodiment, the acrylonitrile butadiene styrene (ABS) and the polypropylene (PP) have good heat resistance and mechanical strength, which helps to enhance the durability and strength of the main control board box as a whole, and ensures that the main control board 200 can work stably under various environmental conditions. In addition, the acrylonitrile butadiene styrene (ABS) and the polypropylene (PP) have low cost, which can effectively reduce the cost.

[0085] The embodiment of the application further provides a refrigeration equipment, which can include a box body, and the refrigeration equipment main control board box is arranged in the box body. The refrigeration equipment can further include a compressor bin, and the box cover 300 of the main control board box can be connected with the side wall of the compressor bin.

[0086] In the embodiment, the refrigeration equipment can be a standalone refrigeration equipment, or a combined refrigeration equipment in which multiple refrigeration compartments are separated from each other and can realize synchronous refrigeration.
