Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to a radiator. Background Technology

[0002] An air-to-ethylene glycol radiator is a liquid-to-air heat exchanger that allows a high-temperature aqueous solution of ethylene glycol to flow through internal pipes while a fan forces it across external fins. This dissipates the heat from the pipes into the air, thus cooling the coolant. The titanium alloy is corrosion-resistant and suitable for use with corrosive aqueous solutions of ethylene glycol.

[0003] The prior art patent document CN220021096U provides a reversing valve, including a base plate with multiple heat pipes on the base plate. The free ends of the heat pipes are provided with heat dissipation fins. The heat pipes are divided into evaporation zones and condensation zones along the direction away from the base plate. The base plate is provided with slots, and the evaporation zones are fixed in the slots. The evaporation zones are heated in contact with the base plate and then transfer the heat to the condensation zones. The heat on the heat dissipation fins and the condensation zones is carried away by wind and air. Compared with the later addition of heat dissipation fins to the heat pipes, the heat pipes and heat dissipation fins of this utility model are integrally formed, and the thermal resistance between the heat dissipation fins and the heat pipes is smaller, so the heat dissipation efficiency of the heat pipes is higher. The heat dissipation fins are directly carved out of the heat pipes using a shaving process, so that the heat dissipation fins and the heat pipes are integrally formed. The heat dissipation fins can be very thin and the processing difficulty is small.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, the heat pipe is set vertically, the coolant stays in the heat pipe for a short time, the heat exchange effect is not good enough, and the coolant is in a laminar flow state, which increases thermal resistance and affects heat exchange efficiency; secondly, the device does not have a good cooling effect by relying on the natural flow of external air during use, and the fan is not easy to disassemble and maintain, which needs to be improved. In view of this, we propose a heat sink. Summary of the Invention

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural diagram of an embodiment of a radiator, including: Please see Figures 1-5This embodiment of a radiator includes a housing 1. An inlet 2 is welded to the top end of the side wall of the housing 1, and an outlet 3 is welded to the bottom end of the side wall of the housing 1. The inlet 2 and outlet 3 are respectively connected to both ends of an external pump body for circulating coolant. A heat dissipation assembly 4 is welded inside the housing 1. The heat dissipation assembly 4 includes multiple distribution heads 401. Two baffles 402 are welded to the top and bottom of the side wall of each distribution head 401. Seals 403 located at the bottom of adjacent baffles 402 are welded to both sides of the top of each baffle 402. Multiple fins 404 are welded to the top of each baffle 402 to form multiple flow channels inside the baffle 402. The distribution heads 401 are used to evenly distribute the coolant through the multiple flow channels for circulating heat dissipation. The baffles 402 absorb heat from the coolant and external airflow for heat dissipation. The top of the baffles 402 and the adjacent baffles 402 are connected to the side wall of the pump body. Multiple flow islands 405 are welded to the bottom of the adjacent partition 402. The flow islands 405 are designed to extend the residence time of the coolant and generate vortices, which severely disrupt the boundary layer of the coolant and greatly improve the heat exchange efficiency of the coolant. Multiple recesses 406 are provided on both sides of the top and bottom of the fins 404. The recesses 406 are designed to generate continuous and stable vortices at the microscopic level, increase the heat exchange area, and improve the heat exchange effect. One of the distribution heads 401 has an inlet pipe 407 welded to the side wall at one end of the inlet port 2, and the other distribution head 401 has an outlet pipe 408 welded to the side wall at one end of the outlet port 3. Multiple fins 409 are welded to the outer wall of the partition 402. The fins 409 are designed to disrupt the boundary layer of the flowing air, increase the heat exchange area, and effectively improve the heat dissipation efficiency of the coolant. Multiple mounting components 5 are snapped into the inner cavity on the back of the shell 1.

[0024] It is worth noting that, in order to facilitate the disassembly and maintenance of the fan, the connecting component 5 specifically includes a frame 501. The fan 502 is threadedly connected to the inner circumference of the frame 501. The fan 502 is used to accelerate airflow after starting, which facilitates heat dissipation of the partition 402 and thus cools the coolant. The frame 501 has receiving grooves 503 on both sides of its side wall. The inner walls of the two receiving grooves 503 are slidably connected with locking blocks 504. The inner walls of the housing 1 have slots 505 on both sides of its inner cavity. The locking blocks 504 are used to move into the slots 505. A fixing plate 506 is welded to the inner wall of the housing 1. Multiple springs 507 are welded to the side wall of the fixing plate 506. A moving plate 508 is attached to the other end of the springs 507. The springs 507 are used to drive the moving plate 508 to move outward, so that the locking blocks 504 are kept locked in the slots 505, improving stability and facilitating disassembly and maintenance. The fan 502 is electrically connected to an external power source.

[0025] Subsequently, in order to increase the heat exchange area, specifically, the partition plate 402, the sealing strip 403, the fin 404 and the flow distribution island 405 are all made of titanium alloy, and the cross section of the fin 404 is V-shaped. The partition plate 402, the sealing strip 403, the fin 404 and the flow distribution island 405 made of titanium alloy are convenient for improving corrosion resistance, and are convenient for adapting to corrosive ethylene glycol aqueous solution. Through the plurality of fins 404 with V-shaped cross sections, it is convenient to splice and form a right-angled wavy shape, which divides the interior of adjacent partition plates 402 into a plurality of fine flow channels, greatly increasing the heat exchange area, making it easier for the cooling liquid to form turbulence, which helps to destroy the thermal boundary layer.

[0026] Meanwhile, in order to make heat exchange more efficient, specifically, the cross section of the flow distribution island 405 is diamond-shaped, and adjacent flow distribution islands 405 are arranged in a staggered manner. The diamond-shaped flow distribution islands 405 facilitate more intense flow separation and vortex of the cooling liquid, and the staggered flow distribution islands 405 facilitate sufficient disturbance to the cooling liquid, thereby efficiently transferring heat to the partition plate 402.

[0027] Further, in order to make the clamping more stable, specifically, the moving plate 508 is made of rigid polyurethane rubber, the clamping groove 505 is in an "L-shaped (right-angled bending shape)" shape, and the size and position of the clamping groove 505 match those of the clamping block 504. The moving plate 508 made of rigid polyurethane rubber has high mechanical strength and strong bearing capacity, which is convenient for improving the sealing performance. The "L-shaped (right-angled bending shape)" clamping groove 505 whose size and position match those of the clamping block 504 facilitates the clamping block 504 to clamp the end of the clamping groove 505 after moving, improving stability and avoiding looseness.

[0028] It is worth noting that, in order to facilitate accurate positioning of the frame 501, specifically, a plurality of positioning grooves 509 are opened on the side wall of the frame 501, a plurality of positioning columns 510 are bonded to the side wall of the moving plate 508, and the size and position of the positioning grooves 509 match those of the positioning columns 510. The positioning columns 510 whose size and position match those of the positioning grooves 509 facilitate positioning of the installation of the frame 501, making the installation guidance more accurate.

[0029] Finally, in order to facilitate stable installation, specifically, a plurality of mounting blocks 6 are welded on both sides of the side wall of the housing 1, and screw holes 7 are opened on the side wall of each of the plurality of mounting blocks 6. Screwing bolts into the screw holes 7 facilitates fixing the mounting blocks 6, thereby stably installing the heat radiator at a required position.

[0030] In addition, the circuits, electronic components and modules involved in the present utility model are all prior art, which can be fully realized by those skilled in the art, and needless to say, the content protected by the present utility model does not involve improvements to internal structures and methods: The models of devices or equipment involved herein can be as follows: Fan 502: DE07020B12U-FAR.

[0031] Combination Figures 1-5 The specific usage process of a heat sink according to this embodiment is as follows: 1: According to the actual use, the inlet 2 and outlet 3 are connected to the two ends of the external pump body respectively. The pump body is started to input the coolant into the distribution head 401 from the inlet pipe 407 at one end of the inlet 2. Multiple fins 404 divide the interior of the adjacent baffles 402 to form multiple flow channels. The coolant is evenly distributed and flows from multiple flow channels. The external airflow dissipates heat from the baffles 402 that absorb the heat of the coolant. Multiple flow islands 405 are welded to make the coolant flow around and generate large vortices. Multiple pits 406 are opened to generate small vortices. The cooled coolant flows out from the outlet 3 at one end of the outlet pipe 408. Multiple fins 409 are welded on the outside of the baffles 402. 2: Insert frame 501 into the inner cavity on the back of housing 1. After the locking block 504 enters the bottom of the slot 505, move the locking block 504 upward and release it. The rebound force of spring 507 causes the moving plate 508 to move outward, which drives the locking block 504 to remain locked inside the slot 505. Start fan 502 to accelerate airflow and dissipate heat from partition 402, so that the coolant is cooled. If fan 502 malfunctions, press frame 501, move the locking block 504 downward, and remove frame 501 to repair fan 502.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
