Description

Technical Field

[0001] The invention relates to the technical field of microchannel radiators, in particular to a high-efficiency microchannel radiator structure. Background Art

[0002] Microchannel radiator is a highly efficient heat exchange device, commonly used in electronic equipment, computers, air conditioning systems and other fields. It consists of multiple tiny channels, which are precisely designed to allow liquid or gas to flow through them, thereby accelerating heat transfer. Since the channel size is very small (usually less than 1 mm), it can significantly improve heat conduction efficiency, reduce thermal resistance, and enhance heat dissipation performance.

[0003] For example, the "microchannel radiator" with the publication number CN103307917B includes upper and lower headers, a heat exchange unit composed of microporous flat tubes and fins, and a microchannel device. The microchannel device includes a box body and a cover plate. Microwires or microspheres are densely arranged in the box body. The box body and the cover plate cooperate to compress the microwires or microspheres, and microchannels are formed between the microwires, between the microwires and the box body, and between the microwires and the cover plate, or between the microspheres, between the microspheres and the box body, and between the microspheres and the cover plate. The heat is transferred to the working medium in the microchannel through the microchannel device in contact with the heat source. The working medium is heated and evaporated to form bubbles, enters the upper header and flows into the heat exchange unit, condenses through the microporous flat tubes and fins, and refluxes by gravity. The structure is simple, the production cost is low, and it has the advantages of pulsating heat pipes and microchannels, which greatly improves the heat transfer efficiency. In particular, when the microspheres are arranged in the cavity, the working medium forms turbulence in the microchannel formed by the microspheres, and the heat dissipation effect is good.

[0004] However, in the prior art, although this type of microchannel radiator has a low production cost and has the effects of pulsating heat pipes and microchannels, it is still lacking in heat dissipation efficiency. Since this type of microchannel radiator dissipates heat for the coolant through a unidirectional micro-tube, when the coolant flows too fast, the contact time between the coolant and the heat sink fins will be reduced, resulting in part of the coolant being unable to be cooled quickly, thereby slowing down the efficiency of lowering the temperature of the coolant. In addition, this type of microchannel radiator does not have a structure for filtering the flowing air, which will cause dust or impurities in the air to adhere to the surface of the heat sink fins when the microchannel radiator is cooled by a fan, thereby further reducing the thermal conductivity of the heat sink fins. In addition, after filtering the air, some filter plates on the market need to be disassembled and replaced when the dust or impurities attached to their surfaces need to be disassembled and replaced. In the process of disassembling and replacing the filter plates, the efficiency of replacing the filter plates is also reduced, thereby reducing the heat dissipation efficiency of the coolant.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the coolant is transported to the cache chamber A through the liquid inlet pipe, and the cache chamber A transports the coolant to the cache chamber B through the micro-tube A. In this process, the multiple micro-tubes A and the multiple micro-grooves inside them separate the coolant, so that it can contact with the heat dissipation fins A to the greatest extent, so that the heat inside the coolant is introduced into the heat dissipation fins A. After the first round of heat dissipation, the initially cooled coolant will flow into the cache chamber C through the drain hole, and then flow to the cache chamber D through the micro-tube B, and then further cooled by the heat dissipation fins B. The design of multiple groups of reflux micro-tubes has the effect of initially cooling and re-cooling the coolant, which improves the cooling efficiency and can also greatly reduce The temperature of the low coolant is reduced; the heat dissipation fins A and B are cooled by the fan. During this process, the filter plate will filter out dust or impurities in the air, thereby preventing dust or impurities from adhering to the heat dissipation fins A and the heat dissipation fins B and reducing the heat dissipation efficiency. When replacing the filter plate, it is only necessary to slide the lever to make the plug-in block slide out of the filter plate. At this time, the filter plate can be pulled out and the new filter plate can be inserted into the slot. At this time, due to the arc-shaped design of the plug-in block, the plug-in block will slide into the frame A after being pressed. After the filter plate is fully inserted into the slot, the plug-in block will be inserted into the filter plate by the elastic force of the spring A, thereby fixing the filter plate, thereby achieving the effect of quick disassembly of the filter plate and improving the efficiency of replacing the filter plate.

[0017] 2. In the present invention, by rotating the screw rod, the screw rod will drive the connecting block to slide upward inside the limit groove B when rotating, and the connecting block will drive the tooth chain to rotate clockwise around gear A and gear B, thereby driving gear A and gear B to rotate, and gear A and gear B will drive air guide plates A and air guide plates B to rotate, thereby realizing the adjustment of the angles of air guide plates A and air guide plates B, and then the hot air blown out by the fan is introduced to the top of the bracket through the air guide plates A and air guide plates B, avoiding the situation that another group of fans inhales the hot air and blows it to the heat dissipation fins B, thereby reducing the heat dissipation efficiency of the heat dissipation fins B. At the same time, when the microchannel radiator is not in use, the frame A is closed through the air guide plates A and air guide plates B, thereby avoiding the situation that dust or impurities in the air enter the interior of the bracket through the frame A and then adhere to the heat dissipation fins A and heat dissipation fins B.

[0018] 3. In the present invention, by toggling the lifting handle, the lifting handle will drive the fixing block to slide inside the mounting plate when it moves. After the fixing block slides out of the fixing hole, the lifting handle can be lifted upward. At this time, the lifting handle will drive the fixing block and the mounting plate to move upward, and the mounting plate will drive the frame B to move upward. After the frame B is away from the bracket, the frame B can be disassembled. When the frame B needs to be installed, it is only necessary to insert the mounting plate in the middle of the bracket and make the frame B fit the bracket. At this time, the lifting handle is released, and the fixing block will be inserted into the fixing hole by the elastic force of the spring C, thereby completing the fixation of the mounting plate and the frame B. The convenient disassembly and assembly design of the installation not only facilitates the quick disassembly and assembly of the frame B, but also does not require the use of disassembly and assembly tools to disassemble it during the disassembly and assembly process, thereby facilitating the maintenance personnel to repair the microchannel radiator.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Reference Figure 1-7As shown: A high-efficiency microchannel radiator structure includes a bracket 100 and a frame A1000, a liquid inlet pipe 101 and a liquid outlet pipe 102 are fixedly installed on the surface of the bracket 100, a micro-tube A103 and a micro-tube B106 are fixedly installed on the surface of the bracket 100, and micro-tubes A103 and B106 are both penetrated with micro-slots 108 inside the micro-tubes A103 and B106, and heat dissipation fins A104 and heat dissipation fins B107 are fixedly installed on the surfaces of the micro-tubes A103 and B106, respectively, a partition 105 is fixedly installed on the surface of the bracket 100, and a cache chamber A109, a cache chamber B110, a cache chamber C112 and a cache chamber D113 are arranged inside the bracket 100, and a drainage hole 111 is penetrated inside the bracket 100, A mounting groove 115 is provided on the surface of frame A1000, a mounting block 114 is fixedly installed on the surface of frame A1000, an insert strip 116 is inserted inside the mounting block 114, a fan 117 is fixedly installed inside the frame A1000, a slot 119 is provided on the surface of frame A1000, a filter plate 118 is inserted inside the slot 119, a limiting slot A120 is provided on the surface of frame A1000, a slide rod A121 is slidably connected inside the frame A1000, an insert block 123 is fixedly installed on one end of the slide rod A121, a lever 124 is fixedly installed on the surface of the insert block 123, a slide rod B125 is fixedly installed inside the frame A1000, a top plate 126 is slidably connected to the surface of the slide rod B125, and a filter plate 118 is inserted inside the frame A1000. The surface of the sliding block 128 and the sliding rod A121 is sleeved with a spring A122, one end of the spring A122 is connected to the surface of the plug block 123, and the other end is connected to the inner surface of the frame A1000. The surface of the sliding rod B125 is sleeved with a spring B127. The plug block 123 is slidably connected to the frame A1000, and the lever 124 is slidably connected to the limiting groove A120. There are two groups of frames A1000, fans 117 and filter plates 118. The two groups of frames A1000, fans 117 and filter plates 118 are symmetrically distributed on both sides of the bracket 100. The two groups of symmetrical fans 117 have the effect of preliminary heat dissipation and further heat dissipation of the coolant, thereby greatly enhancing the cooling efficiency and effect of the coolant. The micro-tubes A103, The micro-tube B106, the heat sink fin A104 and the heat sink fin B107 are all made of copper. Copper has strong thermal conductivity, so that the heat in the coolant can be quickly absorbed and dissipated by the heat sink fin A104 and the heat sink fin B107. The mounting block 114 is slidably connected to the mounting groove 115, the rotating block 128 is threadedly connected to the bracket 100, the top plate 126 is slidably connected to the slot 119, the spring B127 is slidably connected to the frame A1000, the rotating block 128 is threadedly connected to the slide rod B125, one end of the plug block 123 is arc-shaped, and the plug block 123 is slidably connected to the filter plate 118. The sliding design of the plug block 123 and the filter plate 118 makes it easy to fix the filter plate 118 in the slot 119.

[0033] In this embodiment, the coolant is transported to the cache chamber A109 through the liquid inlet pipe 101, and the cache chamber A109 transports the coolant to the cache chamber B110 through the micro-tube A103. In this process, the multiple micro-tubes A103 and the multiple micro-grooves 108 therein separate the coolant, so that it can contact with the heat sink fins A104 to the greatest extent, so that the heat inside the coolant is introduced into the heat sink fins A104. The coolant that has been initially cooled after the first round of heat dissipation will flow into the cache chamber C112 through the drain hole 111, and then flow to the cache chamber D113 through the micro-tube B106, and then further cooled through the heat sink fins B107. The design of multiple groups of reflux micro-tubes has the effect of initially cooling and cooling the coolant again, which improves the cooling efficiency and the contact area between the coolant and the heat sink fins, and can also greatly reduce the temperature of the coolant.

[0034] The fan 117 is used to dissipate heat to the heat dissipation fins A104 and the heat dissipation fins B107. During this process, the filter plate 118 will filter out dust or impurities in the air, thereby preventing dust or impurities from adhering to the heat dissipation fins A104 and the heat dissipation fins B107 and causing a decrease in heat dissipation efficiency. When replacing the filter plate 118, it is only necessary to slide the lever 124 to make the plug block 123 slide out of the filter plate 118. At this time, the filter plate 118 can be pulled out, and then a new filter plate 118 can be inserted into the slot 119. At this time, due to the arc surface design of the plug block 123, the plug block 123 will slide into the frame A1000 after being pressed. After the filter plate 118 is fully inserted into the slot 119, the plug block 123 will be inserted into the filter plate 118 by the elastic force of the spring A122, thereby fixing the filter plate 118, thereby achieving the effect of quickly disassembling the filter plate 118 and improving the efficiency of replacing the filter plate 118.

[0035] By rotating the insert 116, after the insert 116 is rotated out of the bracket 100, the insert 116 can be pulled out of the mounting block 114, and then the frame A1000 is lifted upward, and the frame A1000 will drive the mounting block 114 to slide from the mounting groove 115. After the mounting block 114 slides out of the mounting groove 115, the frame A1000 can be disassembled, so that it is convenient for maintenance personnel to maintain and repair the fan 117 or the microchannel radiator body in the frame A1000. Rotate the rotating block 128, and after the rotating block 128 is rotated away from the sliding rod B125, the rotating block 128 can be pulled out from the frame A1000. After the rotating block 128 is pulled out, the spring B127 on the surface of the sliding rod B125 can be taken out, and then a new spring B127 can be put on the sliding rod B125, and then the rotating block 128 can be fixed to the sliding rod B125 by threads to complete the replacement of the spring B127, thereby avoiding the situation that the spring B127 cannot push the top plate 126 upward when it lacks elasticity.

[0036] Embodiment 2: Figure 8-9 As shown, a frame B200 is provided on the surface of the bracket 100, and an air guide plate A201 and an air guide plate B203 are rotatably connected inside the frame B200, and a gear A202 and a gear B204 are fixedly installed on one end of the air guide plate A201 and the air guide plate B203 respectively, and a toothed chain 205 is sleeved on the surface of the gear A202 and the gear B204, and a connecting block 206 is fixedly installed on the surface of the toothed chain 205, and a screw rod 207 is rotatably connected inside the frame B200, and a limiting groove B208 is provided on the surface of the frame B200, and the number of the frame B200, the air guide plate A201 and the air guide plate B203 is two groups, and the two groups of frames B200, the air guide plates A201 and the air guide plates B203 are symmetrically distributed on both sides of the bracket 100, and the two groups of air guide plates A201 and the air guide plates B203 are symmetrically distributed on both sides of the bracket 100. The design of the wind plate B203 serves to guide the hot air on one side to the higher part of the bracket 100 and the hot air on the other side to the lower part of the bracket 100, thereby preventing the hot air from flowing back through the fan 117. The gear A202 and the gear B204 are both meshed with the tooth chain 205. The design of the tooth chain 205 serves to drive the gear A202 and the gear B204 to rotate when the connecting block 206 drives the tooth chain 205 to rotate, thereby driving the air guide plate A201 and the air guide plate B203 to rotate through the gear A202 and the gear B204. The gear A202 and the gear B204 are both rotatably connected to the frame B200, the connecting block 206 and the screw rod 207 are threadedly connected, and the connecting block 206 and the limit groove B208 are slidingly connected.

[0037] In this embodiment, by rotating the screw rod 207, the screw rod 207 will drive the connecting block 206 to slide upward inside the limiting groove B208, and the connecting block 206 will drive the toothed chain 205 to rotate clockwise around the gear A202 and the gear B204, thereby driving the gear A202 and the gear B204 to rotate, and the gear A202 and the gear B204 will drive the air guide plate A201 and the air guide plate B203 to rotate, thereby realizing the adjustment of the angle of the air guide plate A201 and the air guide plate B203, and then through the air guide plate A201 and the air guide plate B203 guides the hot air blown out by the fan 117 to the top of the bracket 100, so as to prevent another group of fans 117 from sucking in the hot air and blowing it to the heat dissipation fins B107, thereby reducing the heat dissipation efficiency of the heat dissipation fins B107. At the same time, when the microchannel radiator is not in use, the frame A1000 is closed by the air guide plates A201 and B203, thereby preventing dust or impurities in the air from entering the interior of the bracket 100 through the frame A1000 and then attaching to the heat dissipation fins A104 and the heat dissipation fins B107.

[0038] Embodiment 3: According to Figure 10-11 As shown, a mounting plate 300 is fixedly mounted on the top surface of the frame B200, a limiting groove C301 is provided on the surface of the mounting plate 300, a slide bar C302 is slidably connected inside the mounting plate 300, a spring C303 is sleeved on the surface of the slide bar C302, a fixing block 304 is fixedly mounted on one end of the slide bar C302, a handle 305 is fixedly mounted on the surface of the fixing block 304, a fixing hole 306 is provided on the surface of the top plate 126 of the bracket 100, and the mounting plate 300 is slidably connected to the bracket 100. The fixing block 304 is slidably connected to the mounting plate 300, one end of the spring C303 is connected to the surface of the fixing block 304, and the other end is connected to the inner surface of the mounting plate 300. The design of the spring C303 provides power to the fixing block 304. The fixing block 304 is slidably connected to the fixing hole 306. The sliding design of the fixing block 304 and the fixing hole 306 facilitates fixing the mounting plate 300 on the top of the bracket 100, thereby fixing the frame B200.

[0039] In this embodiment, by toggling the handle 305, the handle 305 will drive the fixing block 304 to slide inside the mounting plate 300 when it moves. After the fixing block 304 slides out of the fixing hole 306, the handle 305 can be lifted upward. At this time, the handle 305 will drive the fixing block 304 and the mounting plate 300 to move upward, and the mounting plate 300 will drive the frame B200 to move upward. After the frame B200 is away from the bracket 100, the frame B200 can be disassembled. When the frame B200 needs to be installed, only the mounting plate 306 needs to be lifted upward. 00 is inserted in the middle of the bracket 100, and the frame B200 is fitted with the bracket 100. At this time, the handle 305 is released, and the fixing block 304 is inserted into the fixing hole 306 under the elastic force of the spring C303, thereby completing the fixation of the mounting plate 300 and the frame B200. The convenient disassembly and assembly design of the installation not only facilitates the quick disassembly and assembly of the frame B200, but also does not require the aid of disassembly and assembly tools to disassemble it during the disassembly and assembly process, thereby facilitating the maintenance personnel to repair the microchannel radiator.

[0040] The use method and working principle of the device: When the coolant needs to be cooled, the coolant only needs to be transported to the cache chamber A109, and the cache chamber A109 will transport the coolant to the cache chamber B110 through the micro-tube A103. During this process, the multiple micro-tubes A103 and the multiple micro-grooves 108 inside the micro-tubes A103 will separate the coolant, so that it can contact the heat sink A104 to the greatest extent, so that the heat inside the coolant is introduced into the heat sink A104. After the first round of heat dissipation, the initially cooled coolant will flow into the cache chamber C112 through the drain hole 111, and then flow to the cache chamber D113 through the micro-tube B106, and then further cooled through the heat sink B107. The design of multiple groups of reflux micro-tubes has the effect of initially cooling and cooling the coolant again, which improves the cooling efficiency and the contact area between the coolant and the heat sink fins, and can also greatly reduce the temperature of the coolant.

[0041] When the heat dissipation fins A104 and the heat dissipation fins B107 need to be cooled, the fan 117 is first turned on, and the fan 117 will cool the heat dissipation fins A104 and the heat dissipation fins B107. During this process, the filter plate 118 will filter out dust or impurities in the air, thereby preventing dust or impurities from adhering to the heat dissipation fins A104 and the heat dissipation fins B107 and causing the heat dissipation efficiency to decrease. When replacing the filter plate 118, it is only necessary to slide the lever 124 to make the plug 123 slide out of the filter plate 118. At this time, the top plate 126 will be affected by the elastic force of the spring B127 and will be in the slot 119. The filter plate 118 is pushed out from the slot 119, and the filter plate 118 can be pulled out after being pushed out, and then a new filter plate 118 is inserted into the slot 119. At this time, due to the arc surface design of the plug block 123, the plug block 123 will slide into the frame A1000 after being pressed. After the filter plate 118 is completely inserted into the slot 119, the plug block 123 will be inserted into the filter plate 118 by the elastic force of the spring A122, thereby fixing the filter plate 118, and then achieving the effect of quickly disassembling the filter plate 118, thereby improving the efficiency of replacing the filter plate 118;

[0042] When the frame A1000 needs to be disassembled, the insert 116 only needs to be rotated. After the insert 116 is rotated out of the bracket 100, the insert 116 can be pulled out from the mounting block 114, and then the frame A1000 is lifted upward. The frame A1000 will drive the mounting block 114 to slide out of the mounting groove 115. After the mounting block 114 slides out of the mounting groove 115, the frame A1000 can be disassembled, so that it is convenient for maintenance personnel to maintain and inspect the fan 117 or the microchannel radiator body in the frame A1000. The effect of repairing is achieved by rotating the rotating block 128. At the same time, the rotating block 128 can be pulled out from the frame A1000 after the rotating block 128 is turned away from the slide bar B125. After the rotating block 128 is pulled out, the spring B127 on the surface of the slide bar B125 can be taken out, and then a new spring B127 can be sleeved on the slide bar B125. After the rotating block 128 is fixed to the slide bar B125 through a thread, the spring B127 can be replaced, thereby avoiding the situation that the spring B127 is unable to push the top plate 126 upward when it lacks elasticity.

[0043] When the angle of the air guide plate A201 and the air guide plate B203 needs to be adjusted, it is only necessary to rotate the screw rod 207. When the screw rod 207 rotates, it will drive the connecting block 206 to slide upward inside the limiting groove B208, and the connecting block 206 will drive the tooth chain 205 to rotate clockwise around the gear A202 and the gear B204, thereby driving the gear A202 and the gear B204 to rotate, and the gear A202 and the gear B204 will drive the air guide plate A201 and the air guide plate B203 to rotate, thereby realizing the adjustment of the angle of the air guide plate A201 and the air guide plate B203, and then The hot air blown out by the fan 117 is guided to the top of the bracket 100 through the air guide plate A201 and the air guide plate B203, so as to prevent the hot air from being sucked in by another set of fans 117 and blown to the heat dissipation fins B107, thereby reducing the heat dissipation efficiency of the heat dissipation fins B107. At the same time, when the microchannel radiator is not in use, the frame A1000 is closed through the air guide plate A201 and the air guide plate B203, so as to prevent dust or impurities in the air from entering the inside of the bracket 100 through the frame A1000 and then attaching to the heat dissipation fins A104 and the heat dissipation fins B107.

[0044] When it is necessary to disassemble the frame B200, it is only necessary to move the handle 305. When the handle 305 moves, it will drive the fixing block 304 to slide inside the mounting plate 300. After the fixing block 304 slides out of the fixing hole 306, the handle 305 can be lifted upward. At this time, the handle 305 will drive the fixing block 304 and the mounting plate 300 to move upward, and the mounting plate 300 will drive the frame B200 to move upward. After the frame B200 is away from the bracket 100, the disassembly of the frame B200 is completed. When it is necessary to install the frame B200, it is only necessary to Insert the mounting plate 300 in the middle of the bracket 100, and make the frame B200 fit with the bracket 100. At this time, loosen the handle 305, and the fixing block 304 will be inserted into the fixing hole 306 under the elastic force of the spring C303, thereby completing the fixation of the mounting plate 300 and the frame B200. The convenient disassembly and assembly design of the installation not only facilitates the quick disassembly and assembly of the frame B200, but also does not require the aid of disassembly and assembly tools to disassemble it during the disassembly and assembly process, thereby facilitating maintenance personnel to repair the microchannel radiator.
