Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a cold liquid radiator with multiple flow-guiding channels. Background Art

[0002] The drive motors of new energy vehicles are developing towards high power. As the total power increases, the heating and heat dissipation problems of the power chips in the motor controller will become more serious. This requires the use of high-performance radiators to ensure timely heat dissipation of the chips. The liquid-cooled radiator uses a pump to circulate the coolant in the heat pipe and take away the heat from the upper part of the heating components to achieve heat dissipation and cooling of the heating components. Compared with general air-cooled radiators, liquid-cooled radiators are quiet and have fast and stable cooling, which is suitable for heat dissipation and cooling of new energy power chips. Announcement No.: CN220274160U discloses a multi-channel liquid-cooled radiator, in which the liquid cooling mechanism is a split structure, and the liquid cooling mechanism is embedded between the heat conduction plate seat and the closed plate seat, and the liquid cooling mechanism includes a liquid cooling elbow and a liquid separation connecting seat, and the liquid cooling elbow is embedded between the heat conduction plate seat and the closed plate seat, and a plurality of liquid guide holes for the circulation of cooling liquid are opened in the middle of the liquid cooling elbow. The heat conduction mechanism is set to a split type, and an independent liquid cooling elbow is used as a circulation structure for the cooling liquid. When maintaining the radiator, the liquid cooling elbow can be independently disassembled, which facilitates the maintenance operation of the radiator and can also avoid damage to the chip due to disassembly. The liquid cooling elbow adopts a multi-channel structure, and a plurality of liquid guide holes are opened inside a single liquid cooling elbow, so that the cooling liquid can circulate in multiple liquid guide holes at the same time, which can not only improve the heat dissipation efficiency of the radiator, but also reduce the use cost of the radiator. However, when using the above technology, when the liquid cooling elbow needs to be disassembled independently, the closing plate seat needs to be removed from the heat conducting plate seat. The closing plate seat and the heat conducting plate seat are fixed by bolts, and there are multiple sets of bolts. When disassembling the closing plate seat, multiple bolts need to be unscrewed one by one, which makes the disassembly of the closing plate seat time-consuming and labor-intensive, which is not conducive to improving the convenience of disassembly and maintenance of the liquid cooling elbow and saving disassembly working time. Therefore, improvement is needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical solution: a cold liquid radiator with multiple flow guide channels, including a heat conducting plate, the surface of the heat conducting plate is fixedly connected to a closed plate, the surface of the heat conducting plate is provided with a placement groove, the interior of the placement groove is provided with a liquid cooling elbow, the interior of the liquid cooling elbow is provided with a liquid guide through hole, the surface of the closed plate is fixedly connected to a block, the surface of the heat conducting plate is fixedly connected to a fixed block, the block is clamped with the fixed block, the interior of the block is provided with a slide groove, the interior of the slide groove is slidably connected with a card block, the surface of the card block is fixedly connected to a push plate and a spring, the two ends of the liquid cooling elbow are respectively provided with a liquid inlet end pipe and a liquid outlet end pipe, the liquid inlet end pipe and the liquid outlet end pipe are both fixedly connected to a liquid separation connection seat, and the surface of the liquid separation connection seat is fixedly connected to a liquid cooling interface.

[0005] Preferably, there are two groups of the blocks, which are symmetrically distributed on both sides of the middle of the closing plate, thereby improving the stability of the connection between the closing plate and the heat conducting plate.

[0006] Preferably, a slot is provided on the surface of the fixing block, and the slot is aligned with the slide groove, so as to facilitate inserting the fixing block into the slot.

[0007] Preferably, a handle is fixedly connected to the surface of the closing plate. Here, when the closing plate is disassembled, the closing plate can be easily removed from the heat conducting plate by holding the handle.

[0008] Preferably, a continuous bend section is provided in the middle of the liquid cooling elbow, which can increase the contact area between the liquid cooling elbow and the heat conducting plate, increase the circulation distance of the coolant, and improve the heat dissipation effect of the radiator.

[0009] Preferably, there are three groups of liquid-conducting through-holes, which are evenly spaced within the liquid-cooling elbow. This allows coolant to flow through multiple liquid-conducting through-holes simultaneously, increasing the contact area between the coolant and the liquid-cooling elbow, further improving the heat dissipation efficiency of the radiator, while also reducing the amount of circulating coolant and lowering the cost of the radiator.

[0010] Preferably, the surface of the heat conducting plate is provided with a slot, the interior of which is fixedly connected to a magnet, and the surface of the closing plate is fixedly connected to an insert, which is inserted into the interior of the slot and is adsorbed and connected to the magnet. Here, the insert provides support for the closing plate, and the cooperation between the magnet and the insert further improves the stability of the connection between the closing plate and the heat conducting plate, and makes the edge of the closing plate fit more closely with the edge of the heat conducting plate, avoiding the formation of gaps that could allow dust and flocculent matter from the outside to enter the interior of the heat conducting plate and the closing plate, thereby preventing heat dissipation from the liquid cooling elbow.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. The utility model provides a block, a fixed block, a clamping block, a spring and a push plate structure. When the liquid-cooling elbow is disassembled and repaired, first hold the handle on the closing plate and move the push plate. The push plate drives the clamping block to slide in the slide groove inside the block and squeeze the spring. Then the clamping block is disengaged from the clamping groove on the fixed block. Then the closing plate is removed from the heating plate. Then, the liquid-cooling elbow is taken out of the placement groove on the heat conducting plate. This realizes the fixed connection between the closing plate and the heat conducting plate. Compared with the method of fixing with bolts, this method makes the disassembly and assembly between the closing plate and the heat conducting plate more convenient, which is conducive to improving the convenience and efficiency of disassembly and assembly of the liquid-cooling elbow.

[0013] 2. In the present invention, by providing an insert block and a magnet structure, when the closing plate and the heat conducting plate are fixedly connected, the insert block on the closing plate will be inserted into the slot on the heat conducting plate, and the magnet in the slot will be attracted to the insert block, thereby achieving support for the closing plate by the insert block. At the same time, the cooperation between the magnet and the insert block further improves the stability of the connection between the closing plate and the heat conducting plate, and makes the edge of the closing plate fit more closely with the edge of the heat conducting plate, avoiding the generation of gaps, causing dust and flocs from the outside to enter the interior of the heat conducting plate and the closing plate, so as not to affect the heat dissipation of the liquid cooling elbow.
