[0015] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] In technical solution one and its preferred embodiment, the liquid cooling pipe is laid in the cooling liquid channel of the plate body and passes through the heat exchange part to cooperate with the heat exchange part to form an air-liquid heat exchange structure and cooperate with the plate body to form a liquid cooling plate. Therefore, when the above structure is used to dissipate heat for the heating element in the chamber, a fan can be installed in the chamber and the wind from the fan passes through the heat exchange part. Part of the heating element can be attached to the plate body and dissipate heat through liquid cooling of the liquid cooling pipe, while the part not attached to the plate body and the surface of the heating element not attached to the plate body can dissipate heat through air cooling. Since the heat exchange part introduces the cooling liquid of the liquid cooling pipe, the wind from the fan is significantly cooled after passing through the heat exchange part, thereby improving the heat dissipation efficiency of the wind flow. Therefore, the heat dissipation structure of the present application indirectly introduces the cooling liquid in the liquid cooling pipe into the heat exchange part for air cooling, thereby improving the heat dissipation utilization rate of the cooling liquid in the liquid cooling pipe.

[0017] More importantly, since the liquid cooling pipe directly passes through the heat exchange part to cooperate with the heat exchange part to form an air-liquid heat exchange structure, and cooperates with the plate body to form a liquid cooling plate, compared with the cooling liquid flow channel of the air-liquid heat exchange structure being connected to the liquid inlet and outlet of the liquid cooling plate in other ways (such as parallel connection, separate pipes and welding to the liquid cooling plate), the leakage problem caused by this avoids possible safety hazards. On the other hand, compared with other connection methods, this series connection method does not require the setting of additional adapters, so that the space occupied by the heat exchange part is smaller, which is more conducive to the layout of the heating components when used.

[0018] In technical solution 2 and its preferred embodiment, the structural arrangement of the heat exchange part is easy to process, low in cost, and occupies little space; the liquid cooling pipe at least partially passes through each heat sink along the Y-axis direction, so as to cooperate with each heat sink to form an air-liquid heat exchange structure, which is convenient to process and ensures that the cooling liquid flow channel of the air-liquid heat exchange structure is in full contact with each heat sink, resulting in high heat exchange efficiency.

[0019] In technical solution three and its preferred embodiment, each heat exchange section passes through each heat sink along the Y-axis direction and is arranged at intervals along the Z-axis direction, further ensuring sufficient contact between the cooling section and the heat exchange part, and high heat exchange efficiency.

[0020] In technical solution 4 and its preferred embodiment, the heat dissipation section is connected in series between the cooling sections corresponding to two adjacent heat exchange parts, so that the temperature of the heat dissipation section will be lower than the temperature of one cooling section of the heat exchange parts on both sides and higher than the temperature of the other cooling section. The air flow temperature between the two heat exchange parts is also correspondingly lower. In this way, when the heating element is attached to the surface of the plate, the temperature difference between the part attached to the plate (liquid cooling heat dissipation) and the part not attached to the plate (air cooling heat dissipation) will not be too large, and the heat dissipation will be more balanced.

[0021] In technical solution five and its preferred embodiment, there are two heat exchange parts, the liquid inlet end of the cooling section of one heat exchange part is connected to the liquid inlet, and the liquid outlet end of the cooling section of the other heat exchange part is connected to the liquid outlet. In this way, the temperature of the cooling section corresponding to one heat exchange part is the lowest, and the temperature of the cooling section corresponding to the other heat exchange part is the highest, ensuring that the liquid cooling pipe laid in the cooling liquid channel has a lower temperature, thereby ensuring the liquid cooling effect of the liquid cooling plate while achieving efficient liquid cooling of the heat exchange part and the resulting efficient air cooling.

[0022] In technical solution six and its preferred embodiment, the heat exchange part and the heat dissipation part are respectively located on the first heat dissipation surface and the second heat dissipation surface of the plate body, which is conducive to taking away the heat of the first heat dissipation surface and the second heat dissipation surface of the liquid cooling plate through air cooling. More advantageously, the heating element can be attached to the position of the first heat dissipation surface corresponding to the heat dissipation part or the heating element can be attached to the position of the second heat dissipation surface corresponding to the heat exchange part. In this way, when there is airflow flowing through the heat exchange part or the heat dissipation part, the heat generated by the heating element can be transferred to the heat exchange part or the heat dissipation part through the liquid cooling plate to achieve air cooling and heat dissipation. When the liquid cooling pipe is opened, the heat can be dissipated by liquid cooling and air cooling at the same time. Therefore, the above-mentioned heat dissipation method can be selected according to needs, providing a variety of heat dissipation methods. Among them, the coolant channel opens to the first heat dissipation surface, which is conducive to the liquid cooling pipe passing through the heat dissipation part. In actual applications, the heating element can be attached to the first heat dissipation surface and the second heat dissipation surface respectively to form a module, which is conducive to modular installation and reduces the difficulty of on-site installation.

[0023] In technical solution seven and its preferred embodiment, the radiator is arranged so that a heating element can be placed inside it. In this way, the heat of the heating element can be transferred to the radiator and taken away by air cooling, and can also be transferred to the plate body and taken away by the coolant in the liquid cooling pipe, resulting in high heat dissipation efficiency.

[0024] In technical solution eight and its preferred embodiment, the radiators are arranged at intervals along the Y-axis direction; the radiators and the heat dissipation parts are arranged at intervals along the X-axis direction, so the overall heat dissipation structure occupies a small area in the X-axis direction and the Y-axis direction, which is conducive to its application.

[0025] In technical solution nine and its preferred embodiment, the heat exchange part is located between each radiator and the heat dissipation part along the X-axis direction, which is beneficial for the coolant in the liquid cooling tube to dissipate heat to the heat exchange part, radiator and heat dissipation part respectively. In addition, it is also beneficial to fit the heating element on the first heat dissipation surface on both sides of the heat exchange part along the X-axis direction, and make the air-cooling heat dissipation efficiency of the heating element high.

[0026] In technical solution ten and its preferred embodiment, after the coolant flows in from the liquid inlet, it first passes through the heat exchange part, then passes through the first heat dissipation section (corresponding to the heat dissipation part), and then passes through the second heat dissipation section (corresponding to the radiator) before flowing to the liquid outlet, thereby ensuring the rapid heat dissipation of the liquid cooling of the heat dissipation part, and making the airflow significantly cool down after passing through the heat exchange part, so that the heat dissipation of the heat dissipation part and the radiator is more balanced; in actual application, the electrical component with the largest heat output can be attached to the position of the first heat dissipation surface corresponding to the heat dissipation part, and the electrical component with the smallest heat output can be attached to the position of the first heat dissipation surface corresponding to the radiator, and the electrical component with relatively medium heat output can be placed in the radiator. In this way, the heat dissipation of each electrical component is more balanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] See also Figure 1 , Figure 1 A heat dissipation structure is shown, including a plate body 10 and a liquid cooling pipe 20 .

[0042] The plate body 10 is in the shape of a rectangular parallelepiped, with its length along the X-axis, its width along the Y-axis, and its thickness along the Z-axis. A cooling liquid channel 11 opening on the upper surface of the plate body 10 is provided, on which a heat exchange portion 30 is protruding; a liquid cooling pipe 20 is laid in the cooling liquid channel 11 and passes through the heat exchange portion 30 to form an air-liquid heat exchange structure with the heat exchange portion 30, and to form a liquid cooling plate with the plate body 10. The liquid cooling pipe 20 is provided with a liquid inlet section 21 and a liquid outlet section 22 extending along the X-axis. The liquid inlet section 21 and the liquid outlet section 22 are both located on one side of the plate body 10 along the X-axis. The liquid inlet section 21 and the liquid outlet section 22 are respectively provided with a liquid inlet 01 and a liquid outlet 02, that is, the liquid inlet 01 and the liquid outlet 02 are located on one side of the plate body 10 along the X-axis.

[0043] Specifically, the heat exchange portion 30 protrudes from the plate body 10 along the Z-axis direction and is provided with a plurality of heat sinks 31 extending along the X-axis direction and arranged at intervals along the Y-axis direction. The liquid cooling pipe 20 at least partially penetrates each heat sink 31 along the Y-axis direction, wherein the portion of the liquid cooling pipe 20 penetrating the heat exchange portion 30 forms a cooling section 23. The cooling section 23 includes a plurality of heat exchange sections 231 extending along the Y-axis direction. Each heat exchange section 231 penetrates each heat sink 31 along the Y-axis direction and is arranged at intervals along the Z-axis direction.

[0044] In this embodiment, the liquid cooling pipe 20 is laid in the cooling liquid channel 11 of the plate body 10 and passes through the heat exchange part 30 to cooperate with the heat exchange part 30 to form an air-liquid heat exchange structure and cooperate with the plate body 10 to form a liquid cooling plate. Therefore, when the above structure is used to dissipate heat for the heating element in the chamber, a fan can be installed in the chamber and the wind flow of the fan passes through the heat exchange part 30 along the X-axis direction. Part of the heating element can be attached to the plate body 10 and dissipate heat through the liquid cooling of the liquid cooling pipe 20. The part that is not attached to the plate body 10 and the surface of the heating element that is not attached to the plate body 10 can dissipate heat through air cooling. Since the heat exchange part 30 introduces the cooling liquid of the liquid cooling pipe 20, the wind flow of the fan is significantly cooled after passing through the heat exchange part 30, thereby improving the heat dissipation efficiency of the wind flow. Therefore, the heat dissipation structure of the present application indirectly introduces the cooling liquid in the liquid cooling pipe 20 into the heat exchange part 30 for air cooling, thereby improving the heat dissipation utilization rate of the cooling liquid in the liquid cooling pipe 20.

[0045] More importantly, since the liquid cooling pipe 20 directly passes through the heat exchange part 30 to cooperate with the heat exchange part 30 to form an air-liquid heat exchange structure, and cooperates with the plate body 10 to form a liquid cooling plate, compared with the cooling liquid flow channel of the air-liquid heat exchange structure being connected to the liquid inlet 01 and the liquid outlet 02 of the liquid cooling plate in other ways (such as parallel connection, separate pipes and welding to the liquid cooling plate), the leakage problem caused by this avoids possible safety hazards. On the other hand, compared with other connection methods, this series connection method does not require the setting of additional adapters, so that the space occupied by the heat exchange part 30 is smaller, which is more conducive to the layout of the heating components when used.

[0046] In this embodiment, the heat exchange unit 30 is easy to manufacture, inexpensive, and space-saving. The liquid cooling tube 20 at least partially penetrates each heat sink 31 along the Y-axis, facilitating cooperation with each heat sink 31 to form an air-to-liquid heat exchange structure. This facilitates manufacturing and ensures sufficient contact between the coolant flow path of the air-to-liquid heat exchange structure and each heat sink 31, resulting in high heat exchange efficiency. Each heat exchange segment 231 penetrates each heat sink 31 along the Y-axis and is spaced apart along the Z-axis, ensuring sufficient contact between the cooling segments 23 and the heat exchange unit 30 and high heat exchange efficiency.

[0047] Example 2

[0048] The structure of Example 2 is basically the same as that of Example 1, except that Figure 2 The structure comprises two heat exchange sections 30, which are spaced apart along the X-axis. The liquid cooling tube 20 is further provided with a heat dissipation section 24 connected in series between the cooling sections 23 corresponding to the two adjacent heat exchange sections 30. The heat dissipation section 24 is laid in the coolant channel 11. One of the heat exchange sections 30 is located near the liquid inlet 01 and liquid outlet 02 of the liquid cooling tube 20, and the liquid inlet end of its cooling section 23 is connected to the liquid inlet 01. The liquid outlet end of the cooling section 23 of the other heat exchange section 30 is connected to the liquid outlet 02. Therefore, the liquid inlet section 21 and liquid outlet end of the heat dissipation section 24 are respectively connected to the liquid outlet end of the cooling section 23 of the heat exchange section 30 near the liquid inlet 01 and liquid outlet 02 and the liquid inlet end of the other heat exchange section 30.

[0049] The heat dissipation section 24 is connected in series between the cooling sections 23 corresponding to the two adjacent heat exchange parts 30, so the temperature of the heat dissipation section 24 will be lower than the temperature of one cooling section 23 in the heat exchange parts 30 on both sides and higher than the temperature of the other cooling section 23. The air flow temperature between the two heat exchange parts 30 is also correspondingly lower. In this way, when the heating element is attached to the surface of the plate body 10, the temperature difference between the part attached to the plate body 10 (liquid cooling heat dissipation) and the part not attached to the plate body 10 (air cooling heat dissipation) will not be too large, and the heat dissipation will be more balanced. In this embodiment, the heat exchange There are two heat sections 30, wherein the liquid inlet end of the cooling section 23 of one heat exchange section 30 is connected to the liquid inlet 01, and the liquid outlet end of the cooling section 23 of the other heat exchange section 30 is connected to the liquid outlet 02. In this way, the temperature of the cooling section 23 corresponding to one heat exchange section 30 is the lowest, and the temperature of the cooling section 23 corresponding to the other heat exchange section 30 is the highest, thereby ensuring that the portion of the liquid cooling pipe 20 laid in the cooling liquid channel 11 has a lower temperature, thereby ensuring that the liquid cooling effect of the liquid cooling plate is achieved while achieving efficient liquid cooling of the heat exchange section 30 and the resulting efficient air cooling.

[0050] Example 3

[0051] The structure of Example 3 is basically the same as that of Example 1, except that Figure 3-4 , further comprising a heat dissipation portion 40 and a plurality of heat sinks 50 .

[0052] The plate body 10 is provided with a first heat dissipation surface 12 and a second heat dissipation surface 13 facing away from each other. The heat exchange portion 30 protrudes from the first heat dissipation surface 12 along the Z-axis. The coolant channel 11 opens into the first heat dissipation surface 12 to facilitate the passage of the liquid cooling tube 20 through the heat dissipation portion 40. The heat dissipation portion 40 protrudes from the second heat dissipation surface 13 along the Z-axis and includes a plurality of heat dissipation fins 41 extending along the X-axis and spaced apart along the Y-axis. The heat sink 50 protrudes from the second heat dissipation surface 13 along the Z-axis. Its outer surface is provided with a plurality of heat dissipation fins 51 extending along the X-axis and spaced apart along the Z-axis, protruding along the Y-axis. A cavity 52 is formed within the cavity for accommodating the heating element. Figure 4 In the figure, heat sink 50 has protruding heat dissipation fins 51 on both sides along the Y-axis. The heat sinks 50 are arranged at intervals along the Y-axis; the heat sinks 50 and the heat dissipation unit 40 are arranged at intervals along the X-axis. As a result, the overall heat dissipation structure occupies a small area in the X-axis and Y-axis directions, which is beneficial for its application.

[0053] In this embodiment, the heat exchange portion 30 is located on the first heat dissipation surface 12 of the plate body 10, and the heat dissipation portion 40 and the radiator 50 are both located on the second heat dissipation surface 13 of the plate body 10. This facilitates the removal of heat from the first and second heat dissipation surfaces 12, 13 of the liquid cooling plate through air cooling. More advantageously, a heating element can be attached to the position on the first heat dissipation surface 12 corresponding to the heat dissipation portion 40, or to the position on the second heat dissipation surface 13 corresponding to the heat exchange portion 30. In this way, when air flows through the heat exchange portion 30 or the heat dissipation portion 40, the heat generated by the heating element can be transferred to the heat exchange portion 30 or the heat dissipation portion 40 through the liquid cooling plate, achieving air cooling and heat dissipation. When the liquid cooling tube 20 is opened, heat can be dissipated through both liquid cooling and air cooling. The configuration of the radiator 50 allows the placement of a heating element inside it. In this way, the heat of the heating element can be transferred to the radiator 50 for removal through air cooling, and can also be transferred to the plate body 10 for removal by the coolant in the liquid cooling tube 20, resulting in high heat dissipation efficiency. Therefore, the above-mentioned heat dissipation method can be selected according to needs, providing a variety of heat dissipation methods. In practical applications, the heating element can be attached to the first heat dissipation surface 12 and the second heat dissipation surface 13 respectively to form a module, which is conducive to modular installation and reduces the difficulty of on-site installation.

[0054] In this embodiment, there is one heat exchange unit 30, which is located along the X-axis between each radiator 50 and the heat dissipation unit 40. The liquid cooling tube 20 is provided with a first heat dissipation section 25 and a second heat dissipation section 26 located on either side of the heat exchange unit 30 along the X-axis. The first heat dissipation section 25 and the second heat dissipation section 26 correspond to the heat dissipation unit 40 and the radiator 50, respectively. The liquid inlet and liquid outlet of the cooling section 23 are respectively connected to the liquid inlet O1 and the liquid inlet of the first heat dissipation section 25. The liquid inlet and liquid outlet of the second heat dissipation section 26 are respectively connected to the liquid outlet of the first heat dissipation section 25 and the liquid outlet O2.

[0055] In actual applications, after the coolant flows in from the liquid inlet 01, it first passes through the heat exchange unit 30, then through the first heat dissipation section 25 (corresponding to the heat dissipation section 40), and then through the second heat dissipation section 26 (corresponding to the radiator 50) before flowing to the liquid outlet 02. This ensures rapid heat dissipation of the heat dissipation section 40 by the liquid cooling, and significantly reduces the temperature of the airflow after passing through the heat exchange unit 30, thereby more evenly dissipating the heat of the heat dissipation section 40 and the radiator 50. In actual applications, the electrical component with the highest heat output can be attached to the position of the first heat dissipation surface 12 corresponding to the heat dissipation section 40, while the electrical component with the lowest heat output can be attached to the position of the first heat dissipation surface 12 corresponding to the radiator 50. The electrical component with the highest heat output can be placed in the radiator 50. In this way, the heat dissipation of each electrical component is more evenly distributed. The heat exchange unit 30 is located between each radiator 50 and the heat dissipation section 40 along the X-axis direction, which facilitates the coolant in the liquid cooling tube 20 to dissipate heat from the heat exchange unit 30, radiator 50, and heat dissipation section 40 respectively.

[0056] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
