[0027] In order to describe the present application in detail, the heat exchange device of the present application is described in detail as follows:

[0028] Please refer to Fig. 1 , Fig. 2 and Fig. 3 , the present application provides a heat exchange device, comprising a heat exchange body 7 and a first heat exchange flow channel, the heat exchange body 7 has a heat exchange medium inlet 1 and a heat exchange medium outlet 9; one end of the first heat exchange flow channel is in communication with the heat exchange medium inlet 1, and the other end of the first heat exchange flow channel is in communication with the heat exchange medium outlet 9, wherein the heat exchange body 7 has a first heat exchange area, the first heat exchange flow channel flows through the first heat exchange area, the first heat exchange flow channel has a flow disturbance section and a flow-through section, the flow disturbance section is arranged corresponding to the first heat exchange area, the flow-through section is located outside the first heat exchange area, a plurality of first heat exchange structures 3 are arranged in the flow disturbance section, the first heat exchange structure 3 is protruded from the inner wall of the first heat exchange flow channel into the first heat exchange flow channel, and the inner wall of the flow-through section is smooth. The flow disturbance section of the first heat exchange flow channel is arranged corresponding to the first heat exchange area, a plurality of first heat exchange structures 3 are arranged in the flow disturbance section, by increasing the heat exchange area, the heat exchange efficiency in the flow disturbance section can be enhanced, at the same time, by arranging the flow-through section and the flow disturbance section in the first heat exchange flow channel, compared with the flow channel only provided with the flow disturbance section, the flow resistance in the first heat exchange flow channel can be reduced to a certain extent, and the energy consumption cost of pumping cooling fluid in the first heat exchange flow channel can be reduced.

[0029] The first heat exchange flow channel at least flows through two first heat exchange regions. The first heat exchange flow channel includes first heat exchange branches 6 corresponding to the first heat exchange regions. Each first heat exchange branch 6 flows through a corresponding first heat exchange region. In this embodiment, the first heat exchange flow channel has two first heat exchange regions according to the positions of the heat exchange units 11 at the heat generation positions of the high-power components. The heat generation positions of the high-power components can be accurately cooled. In some embodiments, the number of first heat exchange branches 6 in the first heat exchange flow channel is determined according to the number of first heat exchange regions. The two first heat exchange branches 6 are arranged side by side, which can further reduce the flow resistance in the first heat exchange flow channel. The flow of the heat exchange medium into the first heat exchange branch 6 is distributed as needed, which can avoid the situation that the total flow resistance in the first heat exchange flow channel is significantly increased due to the increase of the flow of the heat exchange medium in the first heat exchange branch 6. In some embodiments, the first heat exchange region corresponds to a temperature sensing unit that needs to be kept at a certain temperature.

[0030] In this embodiment, the heat exchange device is used for cooling the high-power components, and the heat exchange medium is in a liquid state, such as water. In some embodiments, the heat exchange device is used for keeping the temperature of the temperature sensing components, so as to avoid the temperature of the temperature sensing unit of the temperature sensing components being too low and affecting the working state of the temperature sensing components. In other embodiments, the heat exchange medium can be in a gaseous state, such as air or nitrogen.

[0031] The heat exchange body 7 also has a second heat exchange region between the first heat exchange flow channel and the heat exchange medium inlet 1. The second heat exchange region is provided with a second heat exchange flow channel 2 and a third heat exchange flow channel 10 arranged side by side. The second heat exchange flow channel 2 and the third heat exchange flow channel 10 are provided with first heat exchange structures 3. The first heat exchange flow channel is communicated with the heat exchange medium inlet 1 through the second heat exchange flow channel 2. One end of the third heat exchange flow channel 10 is communicated with the heat exchange medium inlet 1. The other end of the third heat exchange flow channel 10 is communicated with the heat exchange medium outlet 9 through a short-circuit flow channel 8. The inner wall of the short-circuit flow channel 8 is smooth. The short-circuit flow channel 8 is arranged side by side with the first heat exchange flow channel. By arranging the second heat exchange flow channel 2 and the third heat exchange flow channel 10 side by side in the second heat exchange region, the size of the first heat exchange flow channel and the short-circuit flow channel 8 flowing into the heat exchange medium inlet 1 can be adjusted during the heat exchange of the second heat exchange region, so as to ensure the uniformity of the distribution of the heat exchange medium in the second heat exchange region, thereby ensuring the consistency of the heat exchange effect of each part in the second heat exchange region. By arranging the short-circuit flow channel 8, the heat exchange medium in the second heat exchange region can be prevented from flowing into the first heat exchange flow channel, thereby increasing the flow resistance of the heat exchange body 7 to the heat exchange medium.

[0032] In the embodiment, the second heat exchange zone is provided with one second heat exchange channel 2 and two third heat exchange channels 10, the second heat exchange channel 2 and the two third heat exchange channels 10 are arranged side by side, and each third heat exchange channel 10 is connected with the heat exchange medium outlet 9 through the same short circuit channel 8. The number of the third heat exchange channels 10 can be adjusted according to actual needs.

[0033] In the second heat exchange channel 2 and the third heat exchange channel 10, the two sides of the long strip-shaped flow disturbance protrusion 4 are provided with a plurality of first heat exchange structures 3, and the first direction intersects the extension direction of the second heat exchange channel 2. By arranging the long strip-shaped flow disturbance protrusion 4, the heat exchange medium can be converged to a certain extent, so as to ensure the uniformity of the temperature of the heat exchange medium. The first flow passage gap 5 in the second heat exchange channel 2 ensures the flow of the heat exchange medium in the second heat exchange channel 2, and the first flow passage gap 5 in the third heat exchange channel 10 ensures the flow of the heat exchange medium in the third heat exchange channel 10. The area of the inlet of the first heat exchange channel into the heat exchange medium is A, the area of the inlet of the short circuit channel 8 into the heat exchange medium is B, B is 1.5 to 3 times of A, so as to better adjust the flow of the heat exchange medium in the second heat exchange channel 2 and the third heat exchange channel 10.

[0034] Specifically, the long strip-shaped flow disturbance protrusion 4 has a second flow passage gap 12 between the protrusion direction of the long strip-shaped flow disturbance protrusion 4 and the inner wall of the second heat exchange channel 2. The second flow passage gap 12 improves the flow of the heat exchange medium in the second heat exchange channel 2 and the third heat exchange channel 10 at the long strip-shaped flow disturbance protrusion 4, which ensures the flow of the heat exchange medium in the second heat exchange channel 2 and the third heat exchange channel 10 while ensuring the uniformity of the temperature of the heat exchange medium. In the embodiment, the size range of the first flow passage gap 5 and the second flow passage gap 12 is 1-4 mm. The above size range value ensures that the cooling liquid is converged to keep the temperature consistent, and ensures that the cooling liquid has small flow resistance in the second heat exchange channel 2 and the third heat exchange channel 10. In the embodiment, the long strip-shaped flow disturbance protrusion 4 is arranged in the area with little or no heat exchange demand.

[0035] In detail, the extending direction of the long strip-shaped turbulence protrusion 4 is perpendicular to the extending direction of the second heat exchange flow channel 2. Since the second heat exchange flow channel 2 and the third heat exchange flow channel 10 are arranged side by side, the extending direction of the long strip-shaped turbulence protrusion 4 is perpendicular to the extending direction of the second heat exchange flow channel 2 and the third heat exchange flow channel 10. In this way, in the second heat exchange flow channel 2, the distance between the inlet of the second heat exchange flow channel 2 into the heat exchange medium and the long strip-shaped turbulence protrusion 4 is substantially the same. Therefore, after the heat exchange medium converges at the long strip-shaped turbulence protrusion 4, the temperature consistency of the heat exchange medium is good. Similarly, the long strip-shaped turbulence protrusion 4 in the third heat exchange flow channel 10.

[0036] In the second heat exchange region in the present embodiment, the outlets of the second heat exchange flow channel 2 and the third heat exchange flow channel 10 out of the heat exchange medium are sealed and separated, the outlet of the second heat exchange flow channel 2 out of the heat exchange medium is the inlet of the first heat exchange flow channel into the heat exchange medium, and the outlet of the third heat exchange flow channel 10 out of the heat exchange medium is the inlet of the short circuit flow channel 8 into the heat exchange medium. By changing the size of the outlet of the second heat exchange flow channel 2 out of the heat exchange medium and the outlet of the third heat exchange flow channel 10 out of the heat exchange medium, the heat exchange medium with a flow rate matched therewith can be adjusted to flow into the second heat exchange flow channel 2 and the third heat exchange flow channel 10. If the heat exchange capacity of the corresponding second heat exchange region in the second heat exchange flow channel 2 is large, the flow rate of the heat exchange medium needs to be increased to increase the heat exchange coefficient in the second heat exchange region and ensure the heat exchange in the second heat exchange region. At the same time, due to the increase of the flow rate of the heat exchange medium, the flow resistance in the heat exchange region will be increased. Under the requirement of the heat exchange flow rate, part of the heat exchange medium is introduced into the second heat exchange flow channel 2 to meet the heat exchange requirement of the second heat exchange region, and the other part of the heat exchange medium is discharged through the short circuit flow channel 8, so that the flow resistance in the first heat exchange flow channel is appropriate, the heat exchange medium flow rate is distributed as required, and the heat exchange requirement and the flow resistance requirement of the heat exchange medium are considered.

[0037] In some embodiments, in the second heat exchange region, the outlets of the second heat exchange flow channel 2 and the third heat exchange flow channel 10 out of the heat exchange medium are connected to each other, and the heat exchange medium can be converged when entering the first heat exchange flow channel to ensure the temperature consistency of the heat exchange medium.

[0038] In the present embodiment, the first heat exchange structure 3 is a heat dissipation column, and the ratio of the radius of the heat dissipation column to the gap between two adjacent heat dissipation columns is 1:2. In some embodiments, the first heat exchange structure 3 can be needle-shaped or sheet-shaped. The type of the first heat exchange structure 3 can be adjusted according to actual needs.

[0039] In summary, the first heat exchange flow channel is provided with a turbulence section corresponding to the first heat exchange region, and a plurality of first heat exchange structures 3 are arranged in the turbulence section to enhance the heat exchange efficiency in the turbulence section.

[0040] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application should be covered by the claims of the present application.
