Moreover, the application can be practiced with different and / or same elements in different examples. Additionally, the application provides various examples of the processes and materials used therein, although other processes and / or materials can be used as appreciated.

[0038] Referring to Figures 1 to 4 The heat dissipation device 20 provided by the embodiment of the present application is used for the air conditioner 100, the air conditioner 100 comprises a heating element 10, and the heat dissipation device 20 comprises a fixing plate 21, a fin 22 and a cover plate 23, the fixing plate 21 is provided with a containing cavity 211 for containing a working medium, the fin 22 and the cover plate 23 are connected with the fixing plate 21 respectively, the first surface of the fin 22 is connected with the containing cavity 211, the second surface of the fin 22 is connected with the cover plate 23, and the heat dissipation air duct 24 is formed between the adjacent fins 22 and the cover plate 23, in the case that the fixing plate 21 is used for being connected with the heating element 10, the heat of the heating element 10 is transmitted to the fin 22 for dissipation through the working medium in the containing cavity 211 and the fixing plate 21.

[0039] In this way, by arranging the containing cavity 211 for containing the working medium in the fixing plate 21 of the heat dissipation device 20, the heat of the heating element 10 can be quickly transmitted to the fin 22 for dissipation through the phase change of the working medium, so that the heat dissipation efficiency of the heat dissipation device 20 is improved in the case that the power device of the electric control module in the air conditioner 100 is increased, and the original area, volume and weight of the heat dissipation device 20 are not changed, and the manufacturing cost and maintenance difficulty of the heat dissipation device 20 are reduced.

[0040] Specifically, the air conditioner 100 comprises a heating element 10, which can control the operation process of the air conditioner 100, so that the air conditioner 100 can realize the functions of heating or cooling. The heating element 10 can be an electrically controlled power module. For example, the heating element 10 can be a compressor intelligent power module, a fan intelligent power module, an Insulate-Gate Bipolar Transistor (IGBT), a Fast Recovery Diode (FRD), or a bridge stack.

[0041] The heating element 10 needs to consume electric energy to generate heat during the process of controlling other components of the air conditioner 100 to work. In order to avoid the influence of the generated heat on the work of other components in the air conditioner 100, a radiator 20 is arranged in the air conditioner 100 to process the heat generated by the heating element 10. The radiator 20 can be an aluminum extruded radiator 20 or a plate-fin radiator 20. The present application takes the aluminum extruded radiator 20 as an example for description. The radiator 20 comprises a fixed plate 21 and a fin 22, and the fin 22 can be connected with the fixed plate 21, so that the fixed plate 21 can be used to fix the fin 22, so that the heat on the fixed plate 21 can be transferred to the fin 22 for dissipation. It should be noted that the fixed plate 21 and the fin 22 can be extruded by 6 series or 3 series aluminum alloy.

[0042] The fixed plate 21 is provided with a containing cavity 211 for containing a working medium. The working medium refers to a medium substance used to realize the mutual conversion of heat energy and mechanical energy in thermodynamic engineering, which can transfer heat through state change. For example, the working medium can be methanol, ammonia, or refrigerant, etc. Therefore, under the condition that the fin 22 is connected with the fixed plate 21, the first surface of the fin 22 can extend into the containing cavity 211, so that the first surface of the fin 22 can be in contact with the working medium, so that the working medium can directly transfer heat to the fin 22 for dissipation.

[0043] The fixed plate 21 can be used to connect with the heating element 10, so that the heat generated by the heating element 10 can be transferred to the working medium in the containing cavity 211 through the fixed plate 21, and the heat generated by the heating element 10 can be transferred to the fin 22 for dissipation through the fixed plate 21.

[0044] The heat sink 20 further comprises a cover plate 23, which can be used to form a heat dissipation air duct 24. The channels formed between the adjacent fins 22 allow air flow therethrough, and a portion of the air flow passes through the second surface of the fins 22, resulting in less or even no air flow passing through the bottom end of the fins 22, and thus reducing the efficiency of the air flow in carrying away the heat on the fins 22. By connecting the cover plate 23 to the end surface of the fixing plate 21 and the second surface of the fins 22 respectively, the cover plate 23 can block the air flow from passing through the second surface of the fins 22, so that the air flow can uniformly pass through each part of the fins 22 and carry away the heat on the fins 22. In this way, by connecting the cover plate 23 to the end surface of the fixing plate 21 and the top end of the fins 22 respectively, the heat dissipation air duct 24 can be formed between the adjacent fins 22 and the cover plate 23, and the cover plate 23 can prevent the air flow from blowing out from the top end of the fins 22 when passing through the heat dissipation air duct 24, so that the bottom end of the fins 22 can be blown by the air flow, thereby improving the heat dissipation efficiency of the fins 22.

[0045] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the plurality of accommodating cavities 211 are provided in the fixing plate 21, and one end of the fin 22 is connected to one of the plurality of accommodating cavities 211.

[0046] In this way, the provision of the plurality of accommodating cavities 211 can make the distribution of the refrigerant in the fixing plate 21 more uniform, thereby improving the overall heat dissipation efficiency of the heat sink 20. Moreover, the provision of the plurality of accommodating cavities 211 can increase the contact area between the refrigerant and the fixing plate 21, and a larger contact area means that more heat can be effectively transferred to the fins 22, further improving the heat dissipation effect.

[0047] Specifically, the accommodating cavities 211 can be provided inside the fixing plate 21, and the number of the accommodating cavities 211 provided on the fixing plate 21 can be multiple, which is not limited herein. One end of the fin 22 can be connected to one of the plurality of accommodating cavities 211, and the plurality of accommodating cavities 211 need not be provided corresponding to one fin 22.

[0048] The accommodating cavities 211 can be formed by heating an aluminum alloy bar to a certain temperature (such as about 460°C), then flowing the semi-solid aluminum through an extrusion die with grooves under high pressure to extrude the initial shape of the heat sink 20, then vacuumizing the formed plurality of accommodating cavities 211, filling the working medium into the accommodating cavities 211, then pressing the end of the accommodating cavities 211, and finally welding the accommodating cavities 211 by laser.

[0049] The arrangement of multiple accommodation cavities 211 can make the distribution of working medium in the radiator 20 more uniform, thereby improving the overall heat dissipation efficiency of the radiator 20. When the working medium flows in the radiator 20, it can more effectively absorb and carry away heat, so that the heat dissipation performance of the radiator 20 is improved.

[0050] By arranging multiple accommodation cavities 211, the number of channels inside the radiator 20 can be increased, thereby increasing the contact area of the working medium with the wall of the fixed plate 21. A larger contact area means that more heat can be effectively transferred to the fins 22, further improving the heat dissipation effect.

[0051] The arrangement of multiple accommodation cavities 211 helps to reduce the load of a single accommodation cavity 211 and reduces the risk of damage to the radiator 20 due to overheating or excessive pressure. This helps to improve the stability and durability of the radiator 20 and prolong its service life.

[0052] Different devices and application scenarios may have different heat dissipation requirements for the radiator 20. By arranging multiple accommodation cavities 211, the number and distribution of cooling liquid can be adjusted according to the actual heat dissipation requirements, thereby meeting different heat dissipation requirements, so that the radiator 20 can be more widely applied to various devices and scenarios.

[0053] In some embodiments, the accommodation cavities 211 and the fins 22 can be connected by integral welding or mechanical fixation.

[0054] Please refer to Figures 3 to 5 In some embodiments, the fins 22 include multiple fins 22 arranged on one end surface of the fixed plate 21 or on both end surfaces of the fixed plate 21.

[0055] In this way, by arranging fins 22 on one end surface or both end surfaces of the fixed plate 21, the fin array can be customized according to the actual heat dissipation requirements, so that it can adapt to the heat dissipation requirements of different devices.

[0056] Specifically, the number of fins 22 can be set to multiple, which is not limited here. Multiple fins 22 can be fixed on the fixed plate 21 in an array, and according to the heat dissipation requirements of the air conditioner 100, multiple fins 22 can be arranged on one end surface of the fixed plate 21, or multiple fins 22 can be arranged on the opposite two end surfaces of the fixed plate 21.

[0057] The presence of multiple fins 22 can increase the contact area of the radiator 20 with the airflow, so that multiple fins 22 can transfer heat from the fins 22 to the airflow in a shorter time, thereby improving the heat dissipation efficiency of the radiator 20.

[0058] The design of the plurality of fins 22 not only increases the heat exchange surface area, but also enhances the turbulent flow effect of the airflow, further improving the heat dissipation efficiency. During the heat dissipation process, the fins 22 can more effectively transfer heat, increasing the amount of heat dissipated.

[0059] The design of the plurality of fins 22 allows the heat sink 20 to adapt to different heat dissipation needs. In environments that require the handling of large amounts of heat, such as industrial production environments, the use of a heat sink 20 with a plurality of fins 22 can more effectively dissipate heat, meeting the needs of high heat dissipation.

[0060] The fins 22 not only serve the purpose of heat dissipation, but also enhance the structural strength of the heat sink 20, protecting the structural integrity of the heat sink 20.

[0061] In some embodiments, depending on the needs of the air conditioner 100, the shape of the fins 22 can be straight fins 22, serrated fins 22, or wavy fins 22.

[0062] For example, in the case of straight fins 22, due to the relatively small heat transfer coefficient and resistance coefficient of straight fins 22, they are suitable for use in situations where the flow resistance requirement is strict and the heat exchange coefficient is large. In the case of serrated fins 22, the straight fins 22 can be cut into many small segments and staggered at certain intervals to form intermittent fins 22, which help to break the boundary layer and improve heat transfer efficiency. In the case of wavy fins 22, by changing the direction of fluid flow, forming turbulence, separating and destroying the boundary layer, the heat transfer effect is significantly enhanced. At the same time, the wavy fins 22 also produce a small elastic deformation during heat transfer, further improving the heat exchange efficiency between the fins 22 and the fluid.

[0063] In this way, by adjusting the shape of the fins 22, the fins 22 can include straight fins 22, serrated fins 22, or wavy fins 22, thereby adapting to the heat dissipation needs of different equipment and different environments.

[0064] In some embodiments, the fins 22 can be integrally formed with the fixed plate 21.

[0065] In this way, by integrally forming the fins 22 and the fixed plate 21, the structural strength and stability of the fins 22 can be improved, and there is no connection between the fins 22 and the fixed plate 21, improving the sealing of the accommodation cavity 211. Integrally forming the fins 22 and the fixed plate 21 can reduce the assembly steps in the production process, simplify the production process, improve production efficiency, and reduce production costs.

[0066] In particular, the fin 22 and the fixing plate 21 are integrally formed by a common casting method such as sand casting, pressure casting, or gas pressure casting. For example, the fin 22 and the fixing plate 21 are integrally formed by pouring molten metal or alloy into a mold prepared in advance, and then solidifying and cooling the molten metal or alloy.

[0067] The fin 22 and the fixing plate 21 can be integrally formed by forging. Common forging methods include free forging, die forging, and extrusion forging. For example, the fin 22 and the fixing plate 21 are integrally formed by heating a metal material to a temperature at which the metal material is easily deformed, and then applying pressure to the metal material in a mold to plastically deform the metal material.

[0068] The fin 22 and the fixing plate 21 can be integrally formed by plastic forming. For example, the fin 22 and the fixing plate 21 are integrally formed by stretching, stamping, or rolling a metal material.

[0069] The fin 22 and the fixing plate 21 can be integrally formed by laser melting. For example, the fin 22 and the fixing plate 21 are integrally formed by locally heating a material using a laser beam to melt the material, and then controlling the material to deform.

[0070] The integrally formed structure of the fin 22 and the fixing plate 21 can increase the connection strength between the fin 22 and the fixing plate 21, and prevent the fin 22 and the fixing plate 21 from becoming loose or falling off during use. Since the fin 22 and the fixing plate 21 are integrally formed, the connection between the fin 22 and the fixing plate 21 is generally tighter, which helps to provide better sealing and prevent air leakage or the entry of external impurities. The integrally formed structure can reduce the connection gap between the fin 22 and the fixing plate 21, thereby reducing the resistance of the refrigerant when passing through the gap, and making the refrigerant flow more smoothly. The integrally formed structure has a cleaner and more beautiful appearance, which meets the aesthetic requirements of modern air conditioning products. The integrally forming process generally has high production efficiency, can shorten the production cycle, and reduce production costs.

[0071] Referring to Figure 3 and Figure 4 In some embodiments, the fin 22 and the fixing plate 21 are in a welded or mechanically fixed structure.

[0072] In this way, the fin 22 and the fixing plate 21 are connected by welding, which can achieve high-strength connection and ensure that the fin 22 and the fixing plate 21 are structurally stable during use and are less likely to become loose or break, thereby effectively prolonging the service life of the product. The fin 22 and the fixing plate 21 are connected by mechanical fixation, which can shorten the installation time and facilitate maintenance and replacement.

[0073] Specifically, the fin 22 and the fixing plate 21 can be connected by welding, so as to ensure good sealing between the fin 22 and the accommodating cavity, effectively prevent leakage of the working medium in the accommodating cavity during heat dissipation of the heat generating component 10, and improve the operation efficiency and safety of the radiator. Moreover, welding can tightly combine the fin 22 and the fixing plate 21, reduce the thermal resistance, make the heat of the heat generating component 10 more quickly and uniformly transferred to the fin 22, and improve the heat exchange efficiency. In mass production, the welding process can effectively control the production cost and improve the market competitiveness of the product.

[0074] The fin 22 and the fixing plate 21 can be connected by mechanical fixation, so that due to the variety of mechanical fixation methods, different fixation methods can be selected according to different requirements of the fin 22 and the fixing plate 21. For example, the mechanical fixation can be to connect the fin 22 and the fixing plate 21 by screws, expansion screws or nails, so that the mechanical fixation structure can adapt to various complex application scenarios. Moreover, the mechanical fixation structure is suitable for various materials of the fin 22 and the fixing plate 21, and is suitable for different shapes and sizes of the fin 22 and the fixing plate 21.

[0075] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the air conditioner 100 includes an air inlet 30 and an outdoor fan 40. The air inlet 30 is arranged opposite to the heat dissipation air duct 24 and communicates the heat dissipation air duct 24 with the outside environment. The air inlet 30 is configured to send air to the heat dissipation air duct 24, so that the outdoor fan 40 carries away the hot air blown out of the heat dissipation air duct 24.

[0076] In this way, by arranging the air inlet 30 and the outdoor fan 40 at both ends of the heat dissipation air duct 24, the outside air flow can be blown from the air inlet 30 to the heat dissipation air duct 24, and after heat exchange with the fin 22, the air flow can be carried away by the outdoor fan 40, thereby improving the heat dissipation efficiency of the fin 22.

[0077] Specifically, the air flow required for heat dissipation of the radiator 20 needs to be obtained from the outside environment, so that the air conditioner 100 includes an air inlet 30 and an outdoor fan 40. The air inlet 30 and the outdoor fan 40 can communicate with the outside environment of the air conditioner 100, and the air inlet 30 is arranged opposite to the heat dissipation air duct 24, so that the fresh air of the outside environment of the air conditioner 100 can enter the heat dissipation air duct 24 through the air inlet 30. After absorbing the heat on the fin 22, the fresh air can be quickly discharged to the outside environment under the rapid rotation of the outdoor fan 40.

[0079] In this way, the fixing member 50 is arranged through the fixing hole 11 and the fixing portion 212, so that the fixing portion 212 and the heating member 10 are connected, thereby enhancing the stability between the heating member 10 and the fixing portion 212, and facilitating the heat generated by the heating member 10 to be transmitted.

[0080] Specifically, the air conditioner 100 comprises the fixing member 50, which can be a screw. The fixing plate 21 comprises the fixing portion 212, which can be used to install the fixing member 50. The accommodating cavities 211 are arranged on both sides of the fixing portion 212, and the fixing hole 11 is arranged on the heating member 10, so that the fixing member 50 is arranged through the fixing hole 11 and connected with the fixing portion 212, so that the heating member 10 is fixedly connected with the fixing plate 21.

[0081] Please refer to Figure 4 In some embodiments, the air conditioner 100 comprises the heat-conducting member 60, and the fixing plate 21 and the heating member 10 are connected through the heat-conducting member 60.

[0082] In this way, the heat-conducting member 60 is arranged between the fixing plate 21 and the heating member 10, so that the heat generated by the heating member 10 can be quickly transmitted to the fins 22 through the heat-conducting member 60, thereby improving the heat dissipation efficiency of the radiator 20.

[0083] Specifically, the air conditioner 100 comprises the heat-conducting member 60, and the fixing plate 21 and the heating member 10 are connected through the heat-conducting member 60. The heat-conducting member 60 can be made of a material that improves the heat transmission between two surfaces. For example, the heat-conducting member 60 can be heat-conducting silicone grease or heat-conducting pad, etc. The heat-conducting member 60 is arranged between the heating member 10 and the fixing plate 21, so that the heat generated by the heating member 10 can be quickly transmitted to the fixing plate 21, thereby improving the heat dissipation efficiency of the radiator 20.
