Therefore, it cannot be understood as a limitation on the present utility model.

[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] As mentioned in the background technology, the existing electronic control unit has poor environmental protection and can only be installed in a cabin or box for use. The use environment is limited. For example, it cannot be installed alone on a car chassis. At the same time, the electronic control unit uses air cooling for heat dissipation, and the heat dissipation effect is poor.

[0038] In view of this, please refer to Figure 1-Figure 6 The heat dissipation housing and the electronic control unit structure provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0039] Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, an electric control unit structure is provided, which includes a first electric control element (not shown), a second electric control element (not shown) and a heat dissipation shell, wherein the first electric control element is arranged in the first chamber 101, and the second electric control element is arranged in the second chamber 201.

[0040] The heat dissipation shell can improve the heat dissipation effect of the first electronic control element and the second electronic control element, and at the same time, can protect the first electronic control element and the second electronic control unit. It is easy to understand that the heat dissipation shell improves the heat dissipation effect and protection of the entire electronic control unit structure. The electronic control unit structure can be installed on the chassis of the car, and can also be installed in a compartment or inside a box, which expands the use scenario of the electronic control unit structure.

[0041] Specifically, the heat dissipation shell includes a first containment shell 100 and a second containment shell 200. The first containment shell 100 is provided with a first chamber 101, and the first chamber 101 is used to accommodate a first electronically controlled element. The second containment shell 200 is connected to the first containment shell 100, and the second containment shell 200 is provided with a second chamber 201, and the second chamber 201 is used to accommodate a second electronically controlled element.

[0042] In this embodiment, the first container shell 100 and the second container shell 200 are both rectangular in shape.

[0043] A liquid cooling channel 102 is provided on a side of the first containment shell 100 facing away from the first chamber 101 , or a liquid cooling channel 102 is provided on a side of the second containment shell 200 facing away from the second chamber 201 . The liquid cooling channel 102 is used to dissipate heat for the first electronically controlled element in the first chamber 101 and for dissipating heat for the second electronically controlled element in the second chamber 201 .

[0044] Since the first electronically controlled element and the second electronically controlled element are respectively arranged in the first chamber 101 and the second chamber 201, the first containing shell 100 and the second containing shell 200 can respectively protect the first electronically controlled element and the second electronically controlled element, and can expand the use environment range of the electronic control unit (i.e., the first electronically controlled element and the second electronically controlled element), such as being installed on a car chassis.

[0045] Also, please refer to Figure 6 It is easy to understand that the liquid cooling channel 102 is located between the first chamber 101 and the second chamber 201, which can dissipate heat for the first electric control element in the first chamber 101 and the second electric control element in the second chamber 201 at the same time, thereby reducing the size of the entire electric control unit structure.

[0046] The first electronically controlled element and the second electronically controlled element here can be understood as existing power conversion devices. Since the power conversion devices generate a lot of heat, liquid (such as water) can be injected into the liquid cooling channel 102, and then the first electronically controlled element and the second electronically controlled element can be cooled by water cooling, which is better than air cooling.

[0047] In this embodiment, the liquid cooling channel 102 is a reciprocating meandering groove.

[0048] Also, please refer to Figure 3 A liquid cooling channel 102 is provided on a side of the first containing shell 100 away from the first chamber 101, or a liquid cooling channel 102 is provided on a side of the second containing shell 200 away from the second chamber 201, so as to dissipate heat of the first electronically controlled element and the second electronically controlled element by water cooling, thereby improving the heat dissipation effect.

[0049] It should be noted that in this embodiment, a liquid cooling channel 102 is provided on the side of the first containment shell 100 away from the first chamber 101 . Of course, in other embodiments, a liquid cooling channel 102 may be provided on the side of the second containment shell 200 away from the second chamber 201 .

[0050] Please refer again Figure 1 and Figure 2 The first containing shell 100 includes a first containing shell 110 and a cover plate 120.

When the fasteners are removed, the cover plate 120 and the first containing shell 110 can be easily separated to reveal the internal space of the first containing shell 110, which is convenient for installing and maintaining the first electronic control component.

[0051] The cover plate 120 and the first accommodating shell 110 together define a first chamber 101 , and the first accommodating shell 110 is used to place a first electronically controlled component, wherein a liquid cooling channel 102 is provided on a side of the first accommodating shell 110 away from the first chamber 101 , and the first accommodating shell 110 is connected to the second accommodating shell 200 .

[0052] Among them, in order to facilitate the entry of liquid into the liquid cooling channel 102, the first accommodating shell 110 is also provided with a first water inlet and outlet 105 and a second water inlet and outlet 106. The first water inlet and outlet, the liquid cooling channel 102 and the second water inlet and outlet are connected in sequence. For example, water can be filled in the first water inlet and outlet, the water flows through the liquid cooling channel 102, and finally flows out from the second water inlet and outlet. Of course, it is also possible to fill the second water inlet and outlet with water, the water flows through the liquid cooling channel 102, and finally flows out from the first water inlet and outlet.

[0053] At the same time, the second containing shell 200 includes a second containing shell 210 and a bottom plate 220. The bottom plate 220 is arranged on the second containing shell 210. The bottom plate 220 and the second containing shell 210 jointly define a second chamber 201. The second containing shell 210 is used to place the second electronic control component. The first containing shell 110 and the second containing shell 210 are connected.

[0054] It should be noted that in some embodiments, the electric control element with a higher heat generation between the first electric control element and the second electric control element may be disposed in the first containing shell 100 provided with the liquid cooling channel 102 or the second containing shell 200 provided with the liquid cooling channel 102 .

[0055] In order to improve the sealing performance of the entire heat dissipation housing, the heat dissipation housing also includes a first sealing ring 300, which abuts against the first accommodating shell 110 and the second accommodating shell 210 at the same time. The first sealing ring 300 surrounds the liquid cooling channel 102 to facilitate sealing of the liquid cooling channel 102. In addition, the heat dissipation housing also includes a second sealing ring, which abuts against the cover plate 120 and the first accommodating shell 110 at the same time to seal the first chamber 101.

[0056] At the same time, the heat dissipation housing further includes a third sealing ring, which abuts against the bottom plate 220 and the second accommodating shell 210 at the same time to seal the second chamber 201, thus ensuring that the entire heat dissipation housing is in a fully closed state.

[0057] The first containment shell 100 is provided with a first wire passing hole 103, the second containment shell 200 is provided with a second wire passing hole 202, and the first chamber 101, the first wire passing hole 103, the second wire passing hole 202 and the second chamber 201 are connected in sequence to facilitate the wires of the first electrically controlled element in the first containment shell 100 to pass through the first wire passing hole 103, the second wire passing hole 202 and the second electrically controlled element in the second containment shell 200 for electrical connection, or it can be understood that it is convenient for the wires of the second electrically controlled element in the second containment shell 200 to pass through the second wire passing hole 202, the first wire passing hole 103 and the first electrically controlled element in the first containment shell 100 for electrical connection.

[0058] In addition, please refer to Figure 5 The first accommodating shell 100 is provided with a plurality of electrical connection ports 10 , and the electrical connection ports 10 can be used for electrical connection with the first electric-controlled element, or can also be used for electrical connection with the second electric-controlled element.

[0059] To facilitate the connection between the first receiving shell 100 and the second receiving shell 200, please refer to Figure 3 and Figure 4 The first containing shell 100 is provided with a first connecting hole 104, so that it is convenient to connect with the second containing shell 200 through a fastener (such as a screw) passing through the first connecting hole 104.

[0060] In addition, the second housing shell 200 is provided with a second connection hole 203, so that it is convenient to use a fastener (such as a screw) to connect the second housing shell 200 and the bottom plate 220 through the second connection hole 203. When the fastener is removed, the bottom plate 220 and the second housing shell 210 can be separated to reveal the internal space of the second housing shell 210, which is convenient for installing and maintaining the second electronic control component.

[0061] It should be noted that the first accommodating shell 110 , the cover plate 120 , the second accommodating shell 210 , the bottom plate 220 , the first sealing ring 300 , the second sealing ring, and the third sealing ring can all be manufactured by machining.
