Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of heat exchanger technology, and more specifically to a compact microchannel heat pipe heat exchanger. Background Technology
[0002] Microchannel heat pipe heat exchangers are a new type of heat exchange equipment that combines microchannel heat transfer technology with the high-efficiency heat transfer characteristics of heat pipes. They are mainly used to enhance heat transfer and solve heat dissipation problems in high-power density scenarios. The micron-level flow channels of microchannels greatly increase the heat transfer area, and together with the latent heat of vaporization of the working fluid inside the heat pipe, they can quickly remove heat from high-power heat sources.
[0003] However, in practice, it has been noted that most heat exchangers are currently large in size and cannot be used for heat exchange of small-flow media. They are also not suitable for installation in confined spaces. Furthermore, the heat pipes of heat exchangers are basically integrally molded. When a single heat pipe or a section of heat pipe is damaged, the entire heat exchanger or all the heat pipes inside the heat exchanger need to be replaced. This results in high replacement costs and is very troublesome to disassemble. Utility Model Content
[0004] The purpose of this invention is to provide a compact microchannel heat pipe heat exchanger that utilizes multiple interlocking, easily detachable heat pipes to form the entire heat exchange pipeline. This allows for adjustment of the overall size of the heat exchanger according to requirements, and the heat pipe joints at the connections facilitate quick disassembly and installation, as well as easy replacement of any damaged easily detachable heat pipes. This addresses the technical problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A compact microchannel heat pipe heat exchanger includes multiple staggered removable heat pipes, and adjacent removable heat pipes are connected end to end by heat pipe joints provided at the ends, and the removable heat pipes at the ends are also fixedly connected with heat pipe ends.
[0007] Among them, the detachable heat pipe includes a C-type metal heat pipe. The inner side of the C-type metal heat pipe has a rectangular array of heat energy microchannels, and the inner side of the C-type metal heat pipe is also fixedly connected with a reinforced heat-conducting plate in a rectangular array.
[0008] As a further technical solution of this utility model, the upper and lower ends of the C-shaped metal heat pipe are fixedly connected to the outer heat-conducting plate in a rectangular array, and the reinforcing heat-conducting plate and the outer heat-conducting plate are provided with through holes in a rectangular array.
[0009] As a further technical solution of this utility model, the heat pipe connector includes an outer fixing frame sleeved on the end of the C-shaped metal heat pipe, and the outer fixing frame and the C-shaped metal heat pipe are fixedly connected. The inner side of the outer fixing frame is also integrally provided with a sealing partition.
[0010] As a further technical solution of this utility model, the sealing partition is fixedly connected in a rectangular array with positioning connecting tubes corresponding to the thermal energy microchannels. The ends of the thermal energy microchannels are also provided with positioning grooves, and both ends of the positioning connecting tubes are inserted into the positioning grooves.
[0011] As a further technical solution of this utility model, the heat pipe end includes a connecting hole plate that is directly fixedly connected to the end of the C-shaped metal heat pipe, and the connecting hole plate has holes in a rectangular array that correspond to the thermal energy microchannels, and the holes in the connecting hole plate are connected to the thermal energy microchannels.
[0012] As a further technical solution of this utility model, the end of the connecting plate away from the C-shaped metal heat pipe is integrally provided with a centralized connecting pipe, and the end of the centralized connecting pipe is integrally provided with a threaded pipe joint.

The reinforced heat-conducting plate and the outer heat-conducting plate fixedly connected to the C-shaped metal heat pipe release the heat in the medium. The heat exchange medium around the reinforced heat-conducting plate and the outer heat-conducting plate arranged in a rectangular array can absorb the heat to achieve heat exchange. Moreover, the overall structure is small in size and is suitable for use in relatively narrow locations.
[0017] 2. According to the space available for installation, different numbers of removable heat pipes can be selected. Two removable heat pipes are connected by a heat pipe connector. The outer fixing frame in the heat pipe connector is fixedly connected to the end of the C-shaped metal heat pipe. Both ends of the positioning connecting pipe inside the heat pipe connector are inserted into the inner side of the thermal energy microchannel, thereby connecting the thermal energy microchannels inside the two removable heat pipes. At the same time, this structure also facilitates the individual disassembly of damaged removable heat pipes, thereby reducing maintenance costs.
[0018] 3. In this utility model, the external medium enters the inner side of the centralized connecting pipe and is then evenly distributed through the holes in the centralized connecting pipe corresponding to the heat energy microchannels, ensuring rapid heat exchange in the external medium. Furthermore, the reinforced heat-conducting plate in the C-type metal heat pipe can also strengthen the structural strength of the C-type metal heat pipe and improve its service life.

The heat exchange medium around the reinforced heat-conducting plate 52 and the outer heat-conducting plate 53 arranged in a rectangular array can absorb the heat and realize heat exchange. Moreover, the overall structure is small in size and is suitable for use in relatively narrow locations.
[0032] Furthermore, the heat pipe connector 6 includes an outer fixing frame 61 sleeved on the end of the C-shaped metal heat pipe 51, and the outer fixing frame 61 and the C-shaped metal heat pipe 51 are fixedly connected. The inner side of the outer fixing frame 61 is also integrally provided with a sealing partition 62.
[0033] More specifically, the sealing partition 62 is fixedly connected in a rectangular array with positioning connecting tubes 63 corresponding to the thermal energy microchannel 55. The end of the thermal energy microchannel 55 is also provided with a positioning groove, and both ends of the positioning connecting tube 63 are inserted into the positioning groove.
[0034] By adopting the above technical solution, different numbers of removable heat pipes 5 can be selected according to the space available for installation. Two removable heat pipes 5 are connected by a heat pipe connector 6. The outer fixing frame 61 in the heat pipe connector 6 is fixedly connected to the end of the C-shaped metal heat pipe 51. Both ends of the positioning connecting pipe 63 inside the heat pipe connector 6 are inserted into the inner side of the thermal energy microchannel 55, thereby connecting the thermal energy microchannel 55 inside the two removable heat pipes 5. At the same time, this structure also facilitates the individual disassembly of damaged removable heat pipes 5, thereby reducing maintenance costs.
[0035] Furthermore, the heat pipe end 4 includes a connecting perforated plate 43 that is directly fixedly connected to the end of the C-type metal heat pipe 51, and the connecting perforated plate 43 has holes in a rectangular array corresponding to the thermal energy microchannel 55, and the holes in the connecting perforated plate 43 are connected to the thermal energy microchannel 55.

Then, attach the outer fixing frame 61 of the heat pipe connector 6 to the ends of the C-shaped metal heat pipes 51 on both sides. Simultaneously, insert both ends of the positioning connecting pipe 63 into the inner side of the thermal energy microchannel 55, thus connecting the thermal energy microchannels 55 inside the two removable heat pipes 5. Next, install the connecting plate 43 onto the ends of the C-shaped metal heat pipes 51. External media enters through the central connecting pipe 41 into the holes in the connecting plate 43 corresponding to the thermal energy microchannels 55. The external media passes through the thermal energy microchannels 55 inside the C-shaped metal heat pipes 51. The reinforced heat-conducting plate 52 and the outer heat-conducting plate 53 fixedly connected to the thermal energy microchannels 55 release heat from the external media. The heat exchange medium surrounding the rectangular array of reinforced heat-conducting plates 52 and the outer heat-conducting plate 53 absorbs the heat, achieving heat exchange.
