Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation and temperature reduction, and in particular to a water cooling system. Background Art

[0002] If the electronic components of electronic equipment work under high temperature for a long time, they will reduce the frequency or even burn out. This is especially true for high-power, highly integrated automotive engine systems, which are restricted by the installation environment and have poor air circulation, which is not conducive to heat dissipation.

It can be seen that this water-cooling system not only has complex pipes, but also requires a relatively large installation space for the entire system, which is not convenient for installation on the vehicle body.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0032] The following describes the embodiments of the present application in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0033] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0034] An embodiment of the present application provides a water-cooling heat dissipation system, which is used to dissipate heat from an automobile engine system, such as dissipating heat from a controller or a heat sink.

[0035] like Figure 2-Figure 4As shown, the water-cooling heat dissipation system of the embodiment of the present application includes an upper shell 10 and a lower shell 20, and the upper shell 10 and the lower shell 20 form a heat dissipation box of the water-cooling heat dissipation system;

[0036] The top of the upper shell 10 is provided with a liquid injection hole 11;

[0037] The lower shell 20 is an assembly structure integrally formed by an aluminum extrusion process, and the outer surface of the side wall of the lower shell 20 is provided with a circumferential special-shaped heat dissipation tooth plate 21, and a heat-conducting fin 22 is arranged inside. The heat-conducting fin 22 isolates the flow channel in the heat dissipation box, and the opposite side walls of the lower shell 20 are provided with a liquid inlet hole 23 and a liquid outlet hole 24 connected to the flow channel.

[0038] The "circumferential special-shaped heat dissipation tooth plate" described in the embodiment of the present application can be understood as a heat dissipation tooth plate with a special-shaped structure arranged around the outer surface of the side wall of the lower shell. The special-shaped structure refers to a non-streamline structure, such as Figure 3 As shown, the top end of the tooth piece has a bending portion. By providing the bending portion at the top end, the tooth piece is not easily deformed after being hit or bumped, and is also prone to dust accumulation after long-term use.

[0039] The heat dissipation box body of the embodiment of the present application has a certain sealing property, that is, when the liquid injection hole 11, the liquid inlet hole 23 and the liquid outlet hole 24 are sealed, the entire heat dissipation box body is closed to prevent leakage of condensed liquid.

[0040] Compared with the existing water-cooled heat dissipation system, the embodiment of the present application integrates the water tank and the heat dissipation radiator to form a lower shell with a circumferential special-shaped heat dissipation fin. When the upper shell and the lower shell are assembled, a heat dissipation box with a certain sealing performance can be obtained. The number of components to be connected by pipelines can be reduced through integrated processing, which can not only reduce the complexity of system installation, but also reduce the installation space required for the system; and the lower shell of the embodiment of the present application is also provided with heat-conducting fins inside, and the heat-conducting fins isolate the flow channel of the condensate in the heat dissipation box, so that the condensate can fully contact the heat-conducting fins, thereby increasing the heat dissipation effect. In addition, the heat dissipation fins of the water-cooled heat dissipation system of the embodiment of the present application are of a special-shaped structure. Compared with conventional linear heat dissipation fins, the circumferential special-shaped heat dissipation fins are not easy to deform and are not easy to accumulate dust.

[0041] Combination Figure 2 and Figure 5 As shown, in the embodiment of the present application, the liquid inlet hole 23 and the liquid outlet hole 24 of the water-cooled heat dissipation system are connected to the heat dissipation cavity through a fluid pipe to form a fluid closed-loop passage, and a heat dissipation body to be dissipated is arranged in the heat dissipation cavity. The embodiment of the present application does not limit the communication method between the fluid pipe and the heat dissipation cavity, and those skilled in the art can implement it in combination with the existing technology.

[0042] In the embodiment of the present application, condensate is injected into the heat dissipation box through the injection hole 11. After the condensate is injected, the injection hole 11 is sealed by a sealing cover or other accessories. When the automobile engine system needs to dissipate heat, a power mechanism such as a water pump is used to promote the condensate to flow in the heat dissipation box according to the Fig.10 The flow direction shown is flowing in the flow channel. After the condensate passes through the heat dissipation box and flows out through the liquid outlet 24, most of the heat has been dissipated by the heat dissipation box through the heat-conducting fins. After that, when the condensate passes through the fluid pipeline and flows to the heat dissipation cavity, it will absorb the heat in the heat dissipation cavity and flow back into the sealed box from the liquid inlet 23, and then dissipate the heat through the heat-conducting fins in the heat dissipation box and the circumferential special-shaped heat dissipation teeth on the outer wall.

[0043] In some embodiments of the present application, a heat dissipation column 26 is provided on the bottom outer surface of the lower shell 20. By providing the heat dissipation column at the bottom, the heat dissipation efficiency of the system is further increased.

[0044] In some embodiments of the present application, the water cooling system further includes a cooling fan 25 , and a fan mounting portion is further provided at the bottom of the lower shell 20 , and the cooling fan 25 is mounted at the bottom of the lower shell 20 through the fan mounting portion.

[0045] like Figure 4 As shown, the cooling fan 25 can directly blow the bottom cooling column 26 and the peripheral special-shaped cooling tooth plate 21, so as to further accelerate the heat dissipation. In practical applications, those skilled in the art can reasonably set the number of cooling fans according to the heat dissipation requirements.

[0046] In some embodiments of the present application, a plurality of groups of the heat conducting fins 22 are disposed inside the lower shell 20, and adjacent heat conducting fins 22 isolate an S-shaped flow channel in the heat dissipation box. For example, adjacent heat conducting fins 22 are staggered in the heat dissipation box to isolate an S-shaped flow channel.

[0047] To ensure that the condensate can Fig.10 The condensate flows in the flow channel in the direction shown. In the present embodiment, the bottom of each set of heat-conducting fins 22 is arranged on the inner surface of the bottom of the lower shell 20, and the top of each set of heat-conducting fins 22 is welded to the inner surface of the top of the upper shell 10, so that a closed flow channel can be formed. Under the action of a power mechanism such as a water pump, the condensate is prompted to flow in the designed direction.

[0048] exist Figure 7 and Fig. 9 In the lower shell shown, six groups of heat-conducting fins are exemplarily shown, and those skilled in the art can increase or decrease the number of heat-conducting fins according to heat dissipation requirements.

[0049] In other embodiments of the present application, the heat-conducting fin is a special-shaped heat-conducting column structure, and the special-shaped heat-conducting column structure can be understood as an irregular column structure, for example Fig. 9 The special-shaped heat-conducting column structure shown includes a plurality of columns, each of which is connected by a heat-conducting plate. Specifically, for a certain special-shaped heat-conducting column structure, its first end is fixedly connected to the first inner side wall of the lower shell, the second end and the third end adjacent to the first end are respectively fixed to the second inner side wall and the third inner side wall adjacent to the first inner side wall of the lower shell, and the fourth end opposite to the first end and the fourth inner side wall opposite to the first inner side wall are not connected to form an opening; further, the openings of adjacent special-shaped heat-conducting column structures are respectively arranged on different sides (preferably opposite sides) in the lower shell to form an S-shaped channel.

[0050] In this way, during the integrated molding process of the lower shell 20, the heat dissipation column 26 can be coaxially arranged with the column body of the special-shaped heat-conducting column to connect the two, thereby improving the thermal conductivity of the system and increasing the heat dissipation efficiency of the system.

[0051] It should be noted that the embodiment of the present application shows a specific structural form of the thermal fins. In other embodiments of the present application, the thermal fins may also be other common structural forms in the prior art, and the embodiment of the present application does not make specific restrictions on this.

[0052] In addition, it should be noted that the structure of the lower shell of the embodiment of the present application is relatively complex. Taking into account the processing cost of the lower shell, the embodiment of the present application preferably sets the outer shape of the lower shell to a regular shape, such as a square body. In other embodiments of the present application, the lower shell can also be other regular shapes or irregular shapes. When the lower shell is an irregular shape, the heat-conducting fins inside the lower shell can be reasonably set to make the isolated flow channel length as long as possible to improve the heat dissipation efficiency of the system.

[0053] It can be seen from the above embodiments of the present application that the water cooling and heat dissipation system provided by the embodiments of the present application has at least the following advantages:

[0054] First, by integrating the water tank and the radiator to form a lower shell with circumferential special-shaped heat dissipation teeth, the heat dissipation box can be obtained by assembling the upper shell and the lower shell. This can reduce the number of components that need to be connected by pipes, reduce the complexity of system installation, and reduce the installation space required for the system.

[0055] Secondly, by arranging heat-conducting fins inside the lower shell, the heat-conducting fins are used to isolate the flow path of the condensate in the heat dissipation box, so that the condensate can fully contact the heat-conducting fins, thereby increasing the heat dissipation effect.

[0056] Third, by setting the heat dissipation fins of the water cooling system as special-shaped structures, the heat dissipation fins are not easily deformed or dusty in the event of collision or bumping.

[0057] Fourth, by connecting the internal heat-conducting fins with the external heat-dissipating columns, the thermal conductivity of the system is improved and the heat dissipation efficiency is increased.
