Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a high-efficiency radiator. Background Technology

[0002] A radiator is a general term for a series of devices used to conduct and release heat. Radiators include heating radiators and computer radiators, and are mainly used to transfer and dissipate heat from the surface of heat-generating equipment in a timely manner, thereby reducing the surface temperature of the equipment and maintaining normal operating conditions.

[0003] However, many radiators currently used for heat conduction and dissipation exchange heat by circulating cooling water between multiple heat-conducting fins. However, the cooling water stays between the fins for a short time, resulting in a short time for it to absorb heat from the fins and low heat exchange efficiency.

[0004] Therefore, it is necessary to provide a new, high-efficiency heat sink to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency heat sink.

[0006] The present invention provides a high-efficiency radiator, including a shell, a heat-absorbing plate embedded at the bottom of the shell, a heat exchange component fixedly provided at the top of the heat-absorbing plate, a liquid inlet and a liquid outlet on both sides of the heat exchange component, and a cover plate fixedly provided at the top of the shell.

[0007] The heat exchange assembly includes multiple heat exchange fins, the bottom of which is fixedly connected to the top of the heat absorption plate. The multiple heat exchange fins are arranged at equal intervals. Multiple blocking blocks are provided between two adjacent heat exchange fins. The space enclosed between two adjacent heat exchange fins and multiple blocking blocks forms a flow channel. The multiple flow channels are S-shaped. The inlet of the flow channel is located below the outlet. Multiple grooves are provided on both sides of the inner wall of the flow channel.

[0008] Preferably, the liquid inlet includes a first housing, one side of which is fixedly connected to one end of the heat exchange fins, the inner cavity of the first housing is connected to a plurality of flow channel inlets, the bottom of the inner wall of the first housing is inclined, a plurality of flow guide blocks are provided at the bottom of the inner wall of the first housing, one end of each of the plurality of flow guide blocks is fixedly connected to one end of each of the plurality of heat exchange fins, and a liquid inlet pipe is fixedly provided at the top of the first housing, the top end of the liquid inlet pipe penetrating the bottom of the cover plate.

[0009] Preferably, the liquid outlet includes a second housing, one side of which is fixedly connected to the end of the heat exchange fins away from the first housing, the inner cavity of the second housing is connected to a plurality of flow channel outlets, and a liquid outlet pipe is fixedly provided on the top of the second housing, the top end of which penetrates the bottom of the cover plate.

[0010] Preferably, one side of the inner wall of the groove is wavy.

[0011] Preferably, the outer surfaces of the inlet pipe and the outlet pipe are respectively fitted with a plurality of raised rings.

[0012] Preferably, the bottom of the cover plate is fixedly connected to the top of the outer casing by a plurality of screws.

[0013] Compared with related technologies, the high-efficiency heat sink provided by this utility model has the following beneficial effects:

[0014] The cooling water flows upward in an S-shape within the flow channel, and the contact area between the heat exchange fins and the coolant is increased by multiple grooves on the surface of the heat exchange fins. This not only increases the contact time between the coolant and the heat exchange fins but also ensures full contact between them. Through this structure, the heat exchange efficiency between the coolant and the heat exchange fins is increased, thus improving the heat dissipation efficiency of the radiator.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of the overall structure of a high-efficiency radiator provided by this utility model.

[0023] In the specific implementation process, such as Figures 1-5 As shown, a high-efficiency radiator includes a housing 1, with a heat-absorbing plate 2 embedded at the bottom of the housing 1 for adhering to the surface of the heat-generating element and absorbing the heat generated by the heat-generating element. A heat exchange component is fixedly provided at the top of the heat-absorbing plate 2 for transferring the heat stored in the heat-absorbing plate 2. A liquid inlet and a liquid outlet are respectively provided on both sides of the heat exchange component. A cover plate 3 is fixedly provided at the top of the housing 1, and the bottom of the cover plate 3 is fixedly connected to the top of the housing 1 by a plurality of screws 14.

[0024] The heat exchange assembly includes multiple heat exchange fins 4, the bottom of which is fixedly connected to the top of the heat absorption plate 2. The multiple heat exchange fins 4 are arranged at equal intervals. Multiple baffles 5 are provided between two adjacent heat exchange fins 4. The space enclosed between two adjacent heat exchange fins 4 and multiple baffles 5 forms a flow channel 6. The multiple flow channels 6 are all S-shaped. The inlet of the flow channel 6 is located below the outlet. Multiple grooves 7 are opened on both sides of the inner wall of the flow channel 6. One side of the inner wall of the groove 7 is wavy, so that the cooling water enters the flow channel 6 from the inlet and flows from bottom to top in an S-shape along the flow channel 6. The multiple grooves 7 opened on the surface of the heat exchange fins 4 increase the contact area between the surface of the heat exchange fins 4 and the coolant.

[0025] The liquid inlet section includes a first housing 8, one side of which is fixedly connected to one end of the heat exchange fins 4. The inner cavity of the first housing 8 is connected to the inlets of multiple flow channels 6. The bottom of the inner wall of the first housing 8 is inclined. Multiple guide blocks 9 are provided at the bottom of the inner wall of the first housing 8. One end of each guide block 9 is fixedly connected to one end of each heat exchange fin 4. A liquid inlet pipe 10 is fixedly provided at the top of the first housing 8. The top end of the liquid inlet pipe 10 penetrates the bottom of the cover plate 3. Cooling water is injected into the first housing 8 through the liquid inlet pipe 10. Under the separation of the guide blocks 9, the cooling water enters the flow channels 6 from the inlets of the multiple flow channels 6 at the same time.

[0026] The liquid outlet section includes a second housing 11. One side of the second housing 11 is fixedly connected to the end of the heat exchange fins 4 away from the first housing 8. The inner cavity of the second housing 11 is connected to the outlets of multiple flow channels 6. A liquid outlet pipe 12 is fixedly provided on the top of the second housing 11. The top end of the liquid outlet pipe 12 passes through the bottom of the cover plate 3 and is used to collect the cooling water flowing out of the outlets of multiple flow channels 6 so that it finally flows out through the liquid outlet pipe 12.

[0027] Multiple protruding rings 13 are fixedly fitted on the outer surfaces of the inlet pipe 10 and the outlet pipe 12, respectively, to increase friction with the pipe when connecting the pipes, making the pipes less likely to fall off.

[0028] The working principle of this utility model is as follows: In use, the heat-absorbing plate 2 at the bottom of the outer shell 1 is attached to the surface of the heating element to absorb the heat of the heating element. The absorbed heat is transferred to the heat exchange fins 4. Cooling water is then injected into the first shell 8 through the liquid inlet pipe 10. Under the separation of the guide block 9, the cooling water enters the flow channel 6 from the inlet of multiple flow channels 6 at the same time, so that the cooling water flows from bottom to top in an S-shape along the flow channel 6. The multiple grooves 7 opened on the surface of the heat exchange fins 4 increase the contact area between the surface of the heat exchange fins 4 and the coolant. This not only increases the contact time between the coolant and the surface of the heat exchange fins 4, but also makes the coolant fully contact the surface of the heat exchange fins 4. Then the coolant flows into the first shell 8 through the outlet of the flow channel 6, and finally flows out through the liquid outlet pipe 12.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
