[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] In the description of the present utility model, the mention of "embodiment", "one embodiment", "some embodiments", or "other embodiments" means that the specific features, structures, or characteristics described in conjunction with the embodiments are included in at least some embodiments, but not necessarily all embodiments. The repeated appearance of "embodiment", "one embodiment", or "some embodiments" does not necessarily refer to the same embodiment. If the specification describes that a component, feature, structure, or characteristic "may", "might", or "could" be included, then the specific component, feature, structure, or characteristic is not necessarily included. If the specification or claims refer to "a" element, it does not mean that there is only one element. If the specification or claims refer to "an additional" element, it does not exclude the existence of more than one additional element. In addition, the specific features, structures, functions, or characteristics can be combined in any suitable manner into one or more embodiments. For example, the first embodiment can be combined with the second embodiment as long as the specific features, structures, functions, or characteristics associated with these two embodiments do not mutually exclude each other.

[0027] In the description of the present utility model, unless otherwise specified, the ordinal adjectives "first", "second", and "third", etc. are used to describe common objects, which only represent different instances of the same object, rather than implying that the objects described in this way must be in a given order, whether in terms of time, space, sorting, or any other way. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0029] As Figures 1 to 3 shown, the present utility model provides an automotive control unit, including: a first housing 1 and a second housing 2 fixedly connected to the first housing 1; the upper and lower surfaces of the first housing 1 are hollow structures, and first ventilation structures 3 are provided on both outer sides of the first housing 1, and the first ventilation structures 3 are connected to second ventilation structures 4 for heat dissipation through the first ventilation structures 3 and the second ventilation structures 4.

[0030] Among them, the second ventilation structure 4 includes a plurality of fin microtubes 401. The fin microtubes 401 are hollow structures, and both ends are connected to the two inner end faces in the first ventilation structure 3 and are installed in an array. The first ventilation structure 3 includes a third housing 301. The inside of the third housing 301 is a hollow structure. Vent pipes 302 are provided on the third housing 301, and heat dissipation fans 402 are provided at the vent pipes 302.

[0031] It should be noted that a temperature sensor can be provided inside the first housing 1. The temperature situation inside the first housing can be obtained through the temperature sensor. When the temperature exceeds a preset value (such as 40 degrees Celsius), since heat dissipation fans are provided at the vent pipes 302, the heat dissipation fans are started at this time. Among them, the vent pipe where one side of the heat dissipation fan is located is the air inlet, and the vent pipe where the other side of the heat dissipation fan is located is the air outlet. Since the internal temperature rise will cause the fin microtubes 401 to heat up, at this time, air enters the third housing 301 from one of the air inlets, so that the cooling air enters the fin microtubes 401 through the third housing 301 to cool the fin microtubes 401, so that the overall temperature of the control unit is kept lower than the set temperature threshold to achieve temperature reduction.

[0032] Furthermore, in the automotive control unit, the fin microtubes 401 are installed in an array inside the first housing 1 and are arranged with a preset gap.

[0033] Furthermore, in the automotive control unit, the fin microtubes 401 penetrate through the second housing 2 and are finally connected to the first ventilation structure 3.

[0034] Furthermore, in the automotive control unit, air inlet pipes 5 are provided below the third housing 2.

[0035] It should be noted that, among them, the gas can also enter from one of the intake pipes 5 and be blown out from the other intake pipe 5 to achieve cyclic cooling, which can directly cool the relevant heating elements quickly and achieve two-way cooling.

[0036] Furthermore, in the vehicle control unit, the cross-sectional shape of the finned microtube 401 is rectangular.

[0037] Furthermore, in the vehicle control unit, the first housing is a sheet metal part made of SUS316, and the finned microtube 401 is made of SUS316 material.

[0038] Furthermore, in the vehicle control unit, the intake pipe 5 is made of SUS304 material.

[0039] In summary, the present invention, by providing the first ventilation structure and the second ventilation structure, when the temperature exceeds the preset value, starts the cooling fan. The ventilation pipe where one cooling fan is located is the air inlet, and the ventilation pipe where the other cooling fan is located is the air outlet. Since the internal temperature rise will cause the temperature of the finned microtube, at this time, the air enters the third housing from one of the air inlets, and then the cooling air enters the finned microtube through the third housing to cool the finned microtube, so that the overall temperature of the control unit remains lower than the set temperature threshold to achieve cooling. The gas can also enter from one of the intake pipes and be blown out from the other intake pipe to achieve cyclic cooling, which can directly cool the relevant heating elements quickly and achieve two-way cooling.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.

[0041] Although the specific implementation manners of the present invention have been described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that, based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
