Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0033] Electrical equipment typically needs to be integrated into a chassis to isolate it from external moisture and contaminants, protecting it for normal operation. Since electrical equipment generates continuous heat during operation, cooling fans are also required inside the chassis to dissipate this heat and maintain the equipment at a normal ambient temperature. However, as the power and heat dissipation of electrical equipment increase, cooling fans alone are insufficient to meet their cooling needs.

[0034] In view of this, refer to Figures 1 to 6 This application provides a heat dissipation chassis to overcome at least one of the above-mentioned technical problems.

[0035] Reference Figures 1 to 6 A heat dissipation chassis includes a chassis 1, a liquid cooling component 2, a heat dissipation assembly 3, and a circulating fan 4.

[0036] It should be noted that in the following embodiments of this application, a first direction X, a second direction Y, and a third direction Z intersect each other. The first direction X is approximately parallel to the length direction of the entire box 1, the second direction Y is approximately parallel to the width direction of the entire box 1, and the third direction Z is approximately parallel to the thickness direction of the entire box 1.

[0037] The housing 1 includes a first housing section 10 and a second housing section 11 connected in a third direction Z. The first housing section 10 has an electrical cavity 100, and the second housing section 11 has a heat exchange cavity 110. The first housing section 10 has a heat exchange port 101, a first air vent 102, and a second air vent 103 opening towards the second housing section 11. The first air vent 102 connects the electrical cavity 100 and the heat exchange cavity 110, and the second air vent 103 connects the electrical cavity 100 and the heat exchange cavity 110. A liquid cooling component 2 is disposed at the heat exchange port 101. The liquid cooling component 2 has a first heat exchange surface 20 facing the electrical cavity 100 and a second heat exchange surface 21 facing the heat exchange cavity 110. A heat dissipation assembly 3 is disposed in the heat exchange cavity 110 and is thermally connected to the second heat exchange surface 21. The heat dissipation assembly 3 forms a heat exchange channel 30 connecting the first air vent 102 and the second air vent 103. The circulating fan 4 is located at the second air outlet 103. The circulating fan 4 is used to drive the air in the electrical cavity 100 to circulate through the first air outlet 102, the heat exchange channel 30 and the second air outlet 103.

[0038] During use, the power module 7 is installed inside the electrical cavity 100, with the first heat exchange surface 20 facing the electrical cavity 100 for installation and heat dissipation of the power module 7. Simultaneously, a heat dissipation assembly 3 is installed on the second heat exchange surface 21. A circulating fan 4 creates air circulation between the electrical cavity 100 and the heat exchange cavity 110, thereby transferring heat from the electrical cavity 100 to the heat exchange cavity 110 and exchanging heat with the second heat exchange surface 21 and the heat dissipation assembly 3. This facilitates full utilization of the second heat exchange surface 21 of the liquid cooling component 2, reduces the ambient temperature inside the electrical cavity 100, and improves the protection of the power module 7 inside the heat dissipation chassis.

[0039] In some embodiments, refer to Figure 1 and Figure 2 The liquid cooling component 2 is located in the heat exchange chamber 110, and the first heat exchange surface 20 covers the heat exchange port 101, which helps to ensure full utilization of the heat dissipation area of ​​the first heat exchange surface 20 and prevents air from flowing through the heat exchange port 101.

[0040] In some embodiments, refer to Figures 1 to 4The first air vent 102 and the second air vent 103 are both located on one side of the heat dissipation assembly 3, and are arranged in a first direction X. The heat exchange channel 30 includes a first channel 300 connecting the first air vent 102 and a second channel 301 connecting the second air vent 103. The first channel 300 and the second channel 301 are connected to the side of the heat dissipation assembly 3 away from the first air vent 102. Specifically, the heat exchange chamber 110 is divided into an air inlet chamber 1100 connecting the first air vent 102, a transfer chamber 1102 connecting the first channel 300 and the second channel 301, and an air outlet chamber 1101 connecting the second air vent 103. During the operation of the circulating fan 4, the air in the electrical cavity 100 enters the heat exchange cavity 110 through the first air inlet 102, passes through the air inlet chamber 1100, the first channel 300, the transfer chamber 1102, the second channel 301, and the air outlet chamber 1101 in sequence, and then enters the electrical cavity 100 through the second air inlet 103. This facilitates the circulating air to fully exchange heat with the heat dissipation component 3 and the second heat exchange surface 21, thereby improving the utilization rate of the cooling capacity of the liquid cooling component 2.

[0041] In some embodiments, refer to Figure 2 , Figures 4 to 6 The heat dissipation assembly 3 includes a heat sink 31 and a support cover 32. The support cover 32 covers the heat exchange port 101. The side of the support cover 32 facing the heat exchange port 101 has a receiving groove 320. The heat sink 31 is disposed in the receiving groove 320 and is thermally connected to the second heat exchange surface 21. The heat sink 31 divides the receiving groove 320 and forms a first channel 300 and a second channel 301. The support cover 32 has an inlet 321 and an outlet 322. The inlet 321 connects the first air outlet 102 and the first channel 300, and the outlet 322 connects the second air outlet 103 and the second channel 301. The receiving groove 320 formed by the support cover 32 is used to stably install the heat sink 31 and form the first channel 300 and the second channel 301, thereby improving the air circulation effect.

[0042] In some embodiments, refer to Figure 2 At least a portion of the liquid cooling component 2 is embedded in the receiving groove 320. The support cover 32, the liquid cooling component 2, and the heat dissipation component 31 can be pre-integrated and welded together, thereby simplifying assembly and further improving the stability of the liquid cooling component 2.

[0043] In some embodiments, refer to Figure 2 , Figure 5 and Figure 6The support cover 32 includes a main body 323, a first side portion 324, a second side portion 325, and a first partition 326. The first side portion 324 and the second side portion 325 are spaced apart in a first direction X, and the main body 323 is connected between the first side portion 324 and the second side portion 325. The main body 323, the first side portion 324, and the second side portion 325 form the aforementioned receiving groove 320. The first side portion 324 and the second side portion 325 are respectively sealed and connected to the first housing portion 10, and the heat dissipation component 31 is connected to the main body 323. The first partition 326 is provided on the side of the main body 323 facing the first air vent 102. The first partition 326 and the first side portion 324 form an inlet 321, and the first partition 326 and the second side portion 325 form an outlet 322. The heat dissipation enclosure also includes a second partition 12, which is disposed in the heat exchange chamber 110 and spaced between the first air vent 102 and the second air vent 103. The second partition 12 seals and connects the main body 323, the first partition 326, and the second enclosure 11. The first partition 326 and the second partition 12 facilitate the guidance of airflow through the first air vent 102, the first channel 300, the second channel 301, and the second air vent 103 in sequence, improving the stability of air circulation. To improve the sealing effect of the second partition 12, soft sealing strips can be attached to the second partition 12 and the main body 323, the first partition 326, and the second enclosure 11 for sealing connection.

[0044] In some embodiments, refer to Figure 2 The heat sink 31 is configured as a corrugated heat sink, and the heat sink 31 extends in a wavy shape along the first direction X between the first side portion 324 and the second side portion 325. The corrugated heat sink helps to make full use of the space between the first side portion 324 and the second side portion 325 and expand the heat dissipation area, thereby improving the heat dissipation effect.

[0045] Specifically, in some embodiments, reference is made to Figure 2 , Figures 4 to 6 The heat sink 31 has multiple first connecting portions 310 connecting to the second heat exchange surface 21 and multiple second connecting portions 311 connecting to the main body portion 323 in its extending direction. A first partition 326 seals the heat sink 31. At least one first connecting portion 310 and the first partition 326 are arranged opposite each other in the second direction Y, and at least one second connecting portion 311 and the first partition 326 are also arranged opposite each other in the second direction Y. The first partition 326 can be sealed to the heat sink 31 by means of adhesive sealing strips, welding, etc. To reduce the direct airflow between the first partition 326 and the heat sink 31 during air circulation, preventing air from passing through the first channel 300 and the second channel 301 for heat exchange, at least one first connecting portion 310 and at least one second connecting portion 311 are sealed to the first partition 326. (Refer to...) Figure 2At this time, the wavy heat sink 31, positioned opposite to the first separator 326, can block the space between the inlet 321 and the outlet 322, preventing air from flowing directly to the outlet 322 without passing through the first channel 300 and the second channel 301, thereby improving the stability of the guided air to fully exchange heat.

[0046] In some embodiments, refer to Figure 2 , Figures 4 to 6 A gap 5 exists between the second housing section 11 and the main body section 323. The heat dissipation enclosure also includes a seal 6 disposed in the gap 5. The seal 6 is located on the side of the main body section 323 facing the second housing section 11 in the third direction Z. The seal 6 extends along the extension direction of the heat exchange channel 30 and seals the second housing section 11 and the main body section 323, and also seals the second partition member 12. The seal 6 may be a soft sealing strip. It is understood that after some air enters the heat exchange chamber 110 from the first air vent 102, it is referred to... Figure 4 The sealing element 6 forms a flow channel on the outside of the support cover 32 simultaneously with the first channel 300 and the second channel 301, which is conducive to improving the heat exchange effect between the air and the support cover 32, thereby helping to improve the heat dissipation effect of the overall heat dissipation component 3.

[0047] Accordingly, the electrical device provided in this application embodiment includes the aforementioned heat dissipation enclosure and a power module 7, which is attached to the first heat exchange surface 20. It is understood that this electrical device can possess all the technical features and effects of the heat dissipation enclosure, which will not be elaborated upon here.
