Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation technology for electronic devices, and more specifically, to a novel water-cooled heat dissipation pipe. Background Technology
[0002] Currently, in the field of highly integrated power modules, switching devices such as MOSFETs, transistors, and diodes are required. These switching devices frequently perform switching operations. As these electronic devices are in operation for a long time, their power supply will generate extremely high heat, which will affect the optimal operating state of the electronic devices. Therefore, electronic engineers have been committed to researching how to solve the heat dissipation problem of electronic devices during use.
[0003] Currently, the main heat dissipation methods for electronic devices include water cooling, thermal cooling, and air cooling. Existing water cooling methods involve creating a smooth water channel inside the casing to provide liquid flow, which carries away the heat from inside the power supply. However, in actual use, its heat dissipation capacity is very limited due to the limitations of the liquid flow rate and the water channel. Utility Model Content
[0004] The purpose of this invention is to provide a novel water-cooled heat dissipation pipe to solve the problem of limited heat dissipation capacity of traditional water-cooled heat dissipation methods in the background art.
[0005] To achieve the above objectives, the present invention provides a novel water-cooled heat dissipation pipe, which includes multiple heat dissipation blocks distributed inside the water-cooled heat dissipation pipe. Each heat dissipation block corresponds to a heat source. Each heat dissipation block is a long strip-shaped block that is thick in the middle and thin at the edges. The two sides of the heat dissipation block are fixedly connected to the inner wall of the water-cooled heat dissipation pipe.
[0006] Furthermore, the water-cooled heat dissipation pipe is integrally formed with the power module cavity.
[0007] Furthermore, the furthest vertical distance between the side of the heat dissipation block facing the water-cooled heat dissipation pipe and the water-cooled heat dissipation pipe is 2mm.
[0008] Furthermore, the front and rear ends of the heat dissipation block, which are parallel to the water-cooled heat dissipation pipe, are shaped like a fish mouth.
[0009] Furthermore, the heat dissipation condenser is a metal product.
[0010] Furthermore, water-cooling heat dissipation pipes are milled into the power module cavity using CNC machining.
[0011] The beneficial effects of this utility model include:
[0012] 1. This utility model provides a new water-cooled pipe heat dissipation method, which achieves multi-faceted heat dissipation and diversion heat dissipation by setting heat dissipation blocks inside the water-cooled pipe.
[0013] 2. Heat dissipation blocks are dispersed inside the water channel. When the liquid passes through the water channel, the blocks conduct heat from the heat source into the liquid covering the blocks, thus dissipating heat from the heat source.
[0014] 3. Since the heat dissipation condenser is located in the center of the liquid cooling channel, it plays a role in the forced flow of liquid in the water channel, which can increase the flow resistance and allow the liquid to absorb heat better in the water channel.

[0020] Example 1
[0021] Please see Figure 1As shown, at least one embodiment of this disclosure provides a novel water-cooled heat dissipation pipe that improves the heat dissipation effect of the water-cooled pipe by adding a heat dissipation module to achieve liquid diversion, increase flow resistance, and improve the heat dissipation effect of the water-cooled pipe.
[0022] First, liquid channels are machined into the power module cavity 3 using CNC machining. A heat dissipation condenser 1 is left in the center of the channel, and the two ends of the condenser are milled into a fish-mouth shape to achieve liquid diversion with minimal resistance. A 2mm gap is left between the bottom of the condenser and the cavity to allow the liquid to better cover the heat dissipation condenser 1 and achieve the best heat absorption effect. The heat dissipation condenser 1 is strip-shaped in the center of the water channel, and the front part of the condenser is pointed and oval to better achieve the liquid diversion effect when the liquid enters the cavity.
[0023] Specifically, in this embodiment, a heat dissipation block 1 is provided in the water-cooled heat dissipation pipe 2 at each heat source location.
[0024] Specifically, in this embodiment, when liquid flows into the water channel, the heat dissipation block 1 will achieve forced diversion of the liquid and can end the diversion in stages, so as to achieve the effect of liquid re-merging and increasing the flow rate.
[0025] In this embodiment, since both ends of the heat dissipation block 1 are pointed elliptical shapes in the cavity, when the liquid flows in at the inlet at the other end of the cavity, the heat dissipation block 1 can also play the same diversion role, and the flow resistance is equal.
[0026] Specifically, in this embodiment, during the machining process, a heat dissipation block 1 is reserved inside the water-cooled pipe for each heat source. When the liquid passes through the water channel, the block conducts the heat of the heat source into the liquid covering the block to achieve the heat dissipation effect. Since the block is in the center of the liquid cooling channel and the block in the water channel forces the liquid to flow separately and increases the flow resistance, the liquid in the water channel can better absorb the heat transferred by the block.
[0027] Specifically, in this embodiment, the heat dissipation condenser 1 is a long strip-shaped aluminum alloy block.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
