This necessitates allocating separate cooling channels to each module, leading to complex water channel design, high costs, poor assembly processes, poor compatibility, and hindering mass production. Therefore, those skilled in the art need to provide a new device to address the problems arising from existing equipment. Utility Model Content

Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0018] like Figure 1 As shown, this utility model provides a liquid-cooled housing, mainly including an upper housing 100, which has a first mounting cavity 101. A liquid-cooling module is disposed on the upper housing 100. The liquid-cooling module includes a liquid inlet 1022, a liquid outlet 1023, and a cooling channel 102. The liquid inlet 1022 and the liquid outlet 1023 are both connected to the cooling channel 102. A circulating coolant is disposed in the cooling channel 102. The cooling channel 102 and the first mounting cavity 101 are independent of each other. A heat dissipation protrusion 1011 is disposed in the first mounting cavity 101, and the position of the heat dissipation protrusion 1011 corresponds to the position of the cooling channel 102. A power board 1013 is disposed in the first mounting cavity 101. The power board has multiple electrical interfaces, which can be connected to the low voltage and high voltage of the vehicle, to various motor acquisition signals, and to various oil temperature and oil pressure acquisition signals. A power unit 1014 is provided on the power board 1013. The power unit 1014 can directly abut against the heat dissipation boss 1011. The heat generated by the power unit 1014 is transferred to the cooling channel 101 through the heat dissipation boss 1011 and carried away by the flowing coolant. Alternatively, the heat dissipation boss 1011 abuts against the power board 1013. Figure 11 As shown, the contact position corresponds to the position of the power unit 1014. At this time, the heat generated by the power unit 1014 is transferred to the heat dissipation boss 1011 through the power board 1013, and then to the coolant flowing in the cooling channel 102, where it is carried away by the coolant.

[0019] In this application, by setting a separate cooling channel 102 on the upper housing 100, the heat dissipation of the power unit 1014 and the motor can be carried out separately, improving heat dissipation efficiency and enabling the power unit 1014 to perform at its maximum efficiency. At the same time, the power board 1013 is set inside the upper housing 100, and can be manufactured independently of the component structure of the lower housing 200, thus speeding up the production cycle.

[0020] In one embodiment, such as Figure 1-6As shown, the cooling channel 102 is disposed on the upper side of the upper housing 100. The first mounting cavity 101 is disposed on the lower side of the upper housing 100. A first clearance groove 1012 is provided on the upper housing 100 to allow space for a first component 1015 protruding to a certain height on the power board 1013, such as a bus capacitor and a common-mode inductor. The first clearance groove 1012 and the cooling channel 102 are independent of each other, with the cooling channel 102 positioned close to the first clearance groove 1012. In this embodiment, the cooling channel 102 is arranged around three sides of the first clearance groove 1012. By adopting the above structure, the heat generated by components such as the bus capacitor and the common-mode inductor can be carried away by the coolant within the cooling channel 102.

[0021] In the above embodiments, when the cooling channel 102 is located on the upper side of the upper housing 100, the power unit 1014 can be configured in the following ways: Figure 6 As shown, the power unit 1014 can be directly and detachably mounted on the heat dissipation boss 1011. At this time, the power unit 1014 is provided with multiple pins of a certain length, and corresponding connection holes are provided on the power board 1013. The pins pass through the connection holes and are fixed by soldering, thereby realizing the electrical connection between the power unit 1014 and the power board 1013.

[0022] Optionally, the power unit 1014 may be multiple chips arranged alternately on the power board 1013, such as... Figure 3 and Figure 4 As shown, a corresponding number of heat dissipation protrusions 1011 are provided in the first mounting cavity 101 of the upper housing 100. The multiple heat dissipation protrusions 1011 respectively abut against the multiple power units 1014 to realize heat transfer.

[0023] Optionally, the power unit 1014 can also be disposed on the lower side of the power plate 1013 near the lower housing 200, such as... Figure 5 As shown, at this time, the heat dissipation boss 1011 directly abuts against the power board 1013, and the abutment position of the power board 1013 and the heat dissipation boss 1011 corresponds to the position of the power unit 1014, that is, at the same position on two opposite sides of the power board 1013. At this time, the heat of the power unit 1014 is transferred to the heat dissipation boss 1011 through the power board 1013, and then transferred to the cooling channel 102 through the heat dissipation boss 1011, and carried away by the flowing coolant.

[0024] Optionally, such as Figure 1 As shown, the power unit 1014 can also be a structure in which multiple chips are arranged in a line or in multiple columns. In this case, the heat dissipation protrusion 1011 directly contacts the power unit 1014 for heat conduction.

[0025] It is understood that in the above embodiments, the heat dissipation protrusion 1011 can cover all power modules 1014, thereby ensuring heat dissipation efficiency.

[0026] In one embodiment, the cooling channel 102 may also be located on the lower side of the upper housing 100, such as... Figure 7-13 As shown, the first mounting cavity 101 is located on the upper side of the upper housing 100. A first through hole 104 is provided on the upper housing 100, communicating with the first mounting cavity 101. The first through hole 104 and the cooling channel 102 are independent of each other. By providing the first through hole 104, when connecting the upper housing 100 and the lower housing 200, a first elastic socket 10131 is provided on the power board 1013 corresponding to the position of the first through hole 104, thereby achieving electrical connection between the power board 1013 and the control motor on the lower housing 200. When the cooling channel 102 is located on the lower side of the upper housing 100, the cooling channel 102 can also dissipate the heat generated by the control motor inside the lower housing 200, further improving the heat dissipation effect inside the lower housing 200.

[0027] Specifically, the lower housing 200 is provided with first plugs in corresponding positions and numbers. The first plugs are electrically connected to the control motor. When the upper housing 100 is installed on the lower housing 200, the first plugs can be aligned and inserted into the first elastic socket 10131 on the upper housing 100. In this embodiment, the first elastic socket 10131 is provided with a Y-shaped opening, which is set towards the lower housing side. The Y-shaped opening can guide the first plug. Since the first plugs and the first elastic socket 10131 are in corresponding positions, blind insertion can be achieved when the upper housing 100 is installed on the lower housing 200, simplifying the assembly process.

[0028] In one embodiment, such as Figure 8 As shown, a first opening is provided on the upper housing, which communicates with the cooling channel 102. A removable first cover plate 1021 is provided at the first opening, which can seal the first opening, thereby forming a complete cooling channel 102. In this embodiment, by providing a removable first cover plate 1021, the interior of the cooling channel 102 can be cleaned, avoiding blockage inside the cooling channel and facilitating later maintenance.

[0029] Furthermore, the first opening extends from the liquid inlet 1022 to the liquid outlet 1023. The shape of the first opening is consistent with the distribution shape of the cooling channel 102. At the same time, the shape and structure of the first cover plate 1021 are consistent with the shape and structure of the first opening. Thus, when the first cover plate 1021 is removed, any position of the cooling channel 102 can be exposed to the view of maintenance personnel, thereby better enabling the cleaning of the cooling channel 102 and facilitating the processing and forming of the cooling channel 102 on the upper shell 100, reducing the difficulty of processing and manufacturing.

[0030] In one embodiment, when the cooling channel 102 is located on the upper side of the upper housing 100, a plurality of metal baffles 105 are provided in the first mounting cavity 101, dividing the first mounting cavity of the upper housing 100 into a plurality of first independent cavities. Specifically, as shown... Figure 2 As shown, the multiple independent cavities are a high-voltage region 1031, a low-voltage region 1033, a transformer region 1032, and a power module region. The transformer region 1032 is located between the high-voltage region 1031 and the low-voltage region 1033. Through a special separate cavity design within the first mounting cavity 101 of the upper housing 100, electromagnetic interference spatial coupling between the high-voltage region 1031, the low-voltage region 1033, the power module region, and the transformer region 1032 is avoided. To enhance the shielding effect of the cavities, it should be noted that when the cooling channel is located on the upper side of the upper housing, the above... Figure 1-6 This structural design is used in all embodiments of the present invention, and will not be described in detail here.

[0031] In one embodiment, such as Figure 4 As shown, in order to simplify the connection lines of each component of the power board 1013, a number of first connection points 1051 are provided on the metal retaining wall 105 at intervals, and a number of corresponding second connection points are provided on the power board. When the power board 103 is installed on the upper housing 100, the first connection points 1051 and the second connection points are electrically connected.

[0032] In one embodiment, regardless of whether the cooling channel 102 is located on the upper or lower side of the upper housing 100, a first flexible socket 1031 is provided on the power board 1013. The first flexible socket 1031 is electrically connected to the power unit 1014 through the power board 1013. As mentioned above, a first plug is provided on the lower housing 200. The first plug can be inserted into the first flexible socket 10131. The details are as described above and will not be elaborated further here.

[0033] In one embodiment, such as Figure 14 and Figure 15As shown, this utility model also provides a vehicle suspension pump control device, including the liquid-cooled housing in the above embodiments; a lower housing 200, which houses a control motor; and an upper housing 100 detachably mounted on the lower housing 200. The connection between the two is a combination of bolt threaded holes or bolt-nut through holes, a conventional structure, which will not be elaborated further here. In this embodiment, the power board 1013 is electrically connected to the control motor, thereby enabling the forward and reverse rotation of the control motor to control the vehicle suspension pump, thus achieving automatic lifting and lowering of the vehicle suspension. These are all prior art technologies and will not be elaborated further here.

[0034] like Figure 16-18 The image shows another embodiment of this utility model, which features a single motor and a single power unit 1014 structure. A single heat dissipation protrusion 1011 is provided, and the cooling channel 102 corresponds to and fully covers the single heat dissipation protrusion 1011, thereby improving heat dissipation efficiency. To further enhance heat dissipation efficiency, multiple arrays of heat dissipation columns can be arranged within the cooling channel 102, thereby increasing the contact area between the coolant and the cooling channel 102 and increasing the heat dissipation area.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
