Description

Technical Field

[0001] The invention relates to the technical field of manifold microchannels, and in particular to an embedded manifold microchannel based on a heat pipe array. Background Art

[0002] Manifold microchannel is an advanced heat exchange or fluid transfer structure. The microchannel design consists of a large number of tiny channels, and the channel size is usually in the order of micrometers to millimeters. These microchannels have a large specific surface area and can provide efficient heat exchange or material transfer interfaces. For example, in some microchannel heat exchangers, the hydraulic diameter of the microchannel may be only a few hundred microns, which greatly increases the contact area between the fluid and the channel wall. The manifold structure is used to distribute and collect fluids. The manifold is usually connected to the microchannel to evenly distribute the fluid to each microchannel, or to collect the fluid flowing out of the microchannel. The design of the manifold can be optimized according to the specific application, such as using different manifold structures such as tree shape and comb shape to achieve better fluid distribution uniformity.

[0003] In energy conversion and storage systems, such as solar collectors, fuel cells, and power transformers, the effective transfer and management of heat is crucial to improving energy conversion efficiency and reducing energy losses. Traditional heat exchangers have some inherent limitations. Conventional shell and tube heat exchangers are large in size, relatively low in heat transfer efficiency, and face challenges in handling high heat flux densities; although plate heat exchangers have high heat transfer efficiency, they have limited sealing performance and pressure resistance, and are difficult to operate reliably under some high-pressure and high-temperature conditions. In addition, these traditional heat exchangers are often limited by space and weight when integrated with miniaturized and lightweight equipment, and cannot meet the needs of modern industry for efficient and compact thermal management. Traditional heat pipes still have some problems in practical applications, such as the connection method between heat pipes and heat dissipation components is not optimized enough, resulting in large contact thermal resistance, affecting the overall heat transfer efficiency; the layout and quantity configuration of heat pipes lack a systematic design method, making it difficult to give full play to their advantages.

[0030] Example 1

[0031] Reference Figure 1-4 , which is the first embodiment of the present invention, provides an embedded manifold microchannel based on a heat pipe array, and the device includes.

[0032] The mounting assembly 100 includes a support base 101, a base 102 fixedly mounted on the upper end of the support base 101, a support plate 103 mounted on the side wall of the base 102, and a cover plate 104 clamped on the top of the support plate 103;

[0033] The heat pipe assembly 200 includes a fixing plate 201 fixedly connected to the side wall of the support plate 103, an adapter 202 fixedly sleeved in the middle of the fixing plate 201, a heat pipe body 203 installed at the end of the adapter 202, and a fin 204 sleeved on the side wall of the heat pipe body 203.

[0034] Among them, the mounting assembly 100 is used to install the heat pipe assembly 200 and maintain the stability of the position of the heat pipe assembly 200. The array-type heat pipe assembly 200 is installed in the middle of the support plate 103, has an extremely high thermal conductivity, and can quickly conduct heat from the heat source to the microchannel. The fixing plate 201 is used to cooperate with the installation of the heat pipe body 203 with the adapter 202, and cooperate with the adapter 202 to maintain the stability of the position of the heat pipe body 203, and is convenient to fix in the middle of the mounting assembly 100. The fins 204 are used to assist the heat pipe body 203 to dissipate heat and transfer the heat evenly outward. The support seat 101 is used to cooperate with fixing the device on the ground installation foundation. The base 102 cooperates with the support plate 103 to dock with the heat pipe assembly 200, which can maintain the stability of the position of the heat pipe assembly 200. The cover plate 104 is used to shield and protect the area above the heat pipe assembly 200.

[0035] Specifically, the heat pipe assembly 200 further includes a connector 205 connected to the side wall of the heat pipe body 203 , and a sleeve 206 threadedly connected to the end of the connector 205 , and the sleeve 206 is sleeved on the outside of the heat pipe body 203 .

[0036] Among them, adding a connector 205 with a sleeve 206 installed on the side wall of the heat pipe body 203 can shield and protect the heat pipe body 203 and improve the heat preservation capacity of the heat pipe body 203.

[0037] Furthermore, the fin 204 is disposed inside the sleeve 206 , and the end of the fin 204 does not contact the inner wall of the sleeve 206 .

[0038] The sleeve 206 is wrapped around the outside of the fin 204 , which can shield and protect the fin 204 and reduce the impact of the external environment on the fin 204 .

[0039] Furthermore, the heat pipe assembly 200 further includes a baffle 207 movable on the inner wall of the sleeve 206 , and a vent 208 disposed on the side wall of the sleeve 206 , and the baffle 207 is plugged into the inner side of the vent 208 .

[0040] A baffle 207 is added to the side wall of the sleeve 206 to close the vent 208 on the side wall of the sleeve 206 . Opening the baffle 207 can connect the vent 208 with the inside of the sleeve 206 , thereby improving the ventilation and heat dissipation capacity inside the sleeve 206 .

[0041] Preferably, the heat pipe assembly 200 further includes a knob 209 rotatably mounted on the side wall of the sleeve 206 , and a rack at an end of the knob 209 is meshed with a rack on the side wall of the baffle 207 .

[0042] A knob 209 is added to the side wall of the sleeve 206. Turning the knob 209 can drive the baffle 207 to move along the inner wall of the sleeve 206 through the side wall rack, adjust the size of the vent 208, and further adjust the ventilation state of the side wall of the sleeve 206 to meet different usage requirements.

[0043] Preferably, the heat pipe assembly 200 further includes a spring piece 210 clamped on the inner wall of the sleeve 206 , and a protrusion at the end of the spring piece 210 is clamped on the side wall of the baffle 207 .

[0044] Among them, the spring piece 210 is installed on the inner wall of the sleeve 206 to connect with the baffle 207. When the end of the baffle 207 moves to the side wall of the spring piece 210, the spring piece 210 will be clamped on the side wall of the end of the baffle 207, cooperate with the inner wall of the sleeve 206 to provide support, limit the baffle 207, and maintain the stability of the position of the baffle 207.

[0045] It should be noted that the side wall of the adapter 202 is clamped in the middle of the slot of the side wall of the support plate 103, and the fixing plate 201 is connected to the side wall of the support plate 103 by bolts.

[0046] Among them, the fixing plate 201 and the support plate 103 are fixed to maintain the stability of the position of the end components of the adapter 202, and loosening the fixing plate 201 facilitates the disassembly and maintenance of the end parts of the adapter 202.

[0047] Specifically, the heat pipe assembly 200 further includes a flange plate 211 fixedly connected to the end of the adapter 202 . A connecting pipe 212 is welded to the end of the flange plate 211 . The connecting pipe 212 is connected to the inside of the adapter 202 .

[0048] Among them, a flange plate 211 with a connecting pipe 212 is added to the end of the adapter 202 to facilitate the connection of two sets of adapters 202, facilitate heating, keep the pipeline connected, and maintain the stability of the pipeline position.

[0049] When in use, the two sets of adapters 202 are connected together through a flange plate 211 with a connecting pipe 212 to keep the pipes connected and transfer heat. When the heat dissipation state of the sleeve 206 needs to be adjusted, turning the knob 209 can drive the baffle 207 to move along the inner wall of the sleeve 206 through the side wall rack, adjust the size of the vent 208, and then adjust the ventilation state of the side wall of the sleeve 206.

[0050] In summary, the heat pipe array has an extremely high thermal conductivity and can quickly transfer heat from the heat source to the microchannel. By rationally designing the layout and number of the heat pipe array, it can effectively collect and transfer heat so that the heat is evenly distributed over the entire microchannel surface, greatly improving the heat exchange efficiency and ensuring that the heat can be dissipated in a timely manner. It is suitable for heat dissipation scenarios with high heat flux density, such as heat dissipation of high-performance electronic chips, high-power lasers and other equipment. The embedded manifold microchannel structure tightly combines the heat pipe array with the microchannel.

[0051] Example 2

[0052] Reference Figure 1-5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a supporting component of the sleeve 206 in the heat pipe assembly 200 is proposed, including;

[0053] The heat pipe assembly 200 further includes a cushion block 213 clamped on the outer wall of the sleeve 206 , a top block 214 movably plugged on the upper end of the cushion block 213 , and a handle bolt 215 threadedly connected to the side wall of the cushion block 213 .

[0054] Among them, the cushion block 213 is added and used in conjunction with the top block 214 to provide support for the sleeves 206 that are close to each other, maintain the stability of the position of the sleeve 206, and prevent the sleeve 206 from being deformed by heat. The handle bolt 215 is tightened to fix the top block 214 at the end of the cushion block 213 to maintain the stability of the combined length of the top block 214 and the cushion block 213.

[0055] Preferably, the side wall of the top block 214 is provided with an arc surface structure matching the bottom of the cushion block 213 , and the end of the handle bolt 215 passes through the cushion block 213 and is used in conjunction with the top block 214 .

[0056] Among them, the top block 214 and the cushion block 213 are provided with a matching arc structure on the side wall, which can adjust the installation direction according to actual needs, adapt to installation at different positions of the side wall of the sleeve 206, support the sleeve 206, and maintain the stability of the position of the sleeve 206.

[0057] When in use, the cushion block 213 and the top block 214 are combined together and docked with the two sets of sleeves 206. After adjusting to an appropriate length, the handle bolt 215 is tightened to fix the top block 214 to the end of the cushion block 213 to maintain the stability of the combined length of the top block 214 and the cushion block 213, and to support and limit the sleeve 206.

[0058] In summary, a highly integrated and miniaturized design is achieved. Compared with the traditional separate heat exchanger, it is conducive to efficient thermal management in a limited space and is particularly suitable for applications with strict requirements on volume and weight. The isothermal property of the heat pipe makes the temperature distribution on the surface of the microchannel more uniform during the heat transfer process. It can be flexibly designed and optimized according to different application requirements and heat source characteristics. By adjusting the size, shape, type of working fluid and structural parameters of the heat pipe, it can adapt to various complex working environments and heat dissipation requirements. At the same time, it can support components such as the sleeve, improve the installation strength of the microchannel components, and prevent the microchannel components from being deformed due to heat, affecting connectivity.
