Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation of intelligent electric cabinets, and specifically to a heat dissipation system of intelligent electric cabinets based on phase change refrigeration. Background Art

[0002] With the rapid development of big data and cloud computing, the heat dissipation problem of smart cabinets has become increasingly prominent. Although traditional liquid cooling technology can achieve a certain heat dissipation effect, it consumes a lot of energy and has limited heat dissipation effect, making it difficult to meet the needs of high-density and high-efficiency heat dissipation. At present, conventional liquid cooling technology uses circulating coolant to remove the heat generated inside the cabinet. However, this method consumes a lot of energy and the heat dissipation effect is not ideal under high load conditions.

[0003] Traditional liquid cooling technology has limited heat dissipation effect, high energy consumption, and is difficult to meet the heat dissipation requirements of multiple sets of electrical cabinets in series or parallel. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides a smart electric cabinet heat dissipation system based on phase change refrigeration, which has the advantages of reducing the heat dissipation energy consumption of the smart electric cabinet, improving the heat dissipation efficiency of the smart electric cabinet, and meeting the heat dissipation needs of multiple groups of electric cabinets in series or parallel. It solves the problems of high heat dissipation energy consumption and poor effect of smart electric cabinets, and difficulty in achieving heat dissipation of multiple groups of electric cabinets in series or parallel.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an intelligent electric cabinet heat dissipation system based on phase change refrigeration, comprising an electric cabinet rear door, a low-temperature phase change refrigeration module is provided on the front of the electric cabinet rear door, the low-temperature phase change refrigeration module is provided with equidistantly arranged filling holes, each of the filling holes is provided with fillers, a single-sided hydraulic inflation plate is provided on the front of the low-temperature phase change refrigeration module, a temperature sensor is provided inside the low-temperature phase change refrigeration module, a controller is provided inside the low-temperature phase change refrigeration module, an outer surface of the low-temperature phase change refrigeration module is fixedly connected to a shell, and two side panels are fixedly connected to the front of the electric cabinet rear door, two control rods are rotatably plugged into the interior of each of the side panels, and a positioning rod is threadedly connected to the interior of each of the control rods.

[0006] Through the above scheme, since the existing intelligent electric cabinets have high heat dissipation energy consumption and poor effect, and it is difficult to achieve heat dissipation of multiple groups of electric cabinets in series or parallel, by setting a low-temperature phase change refrigeration module and adopting phase change refrigeration technology, the heat dissipation energy consumption of the intelligent electric cabinet is greatly reduced, while the heat dissipation effect is improved, and the heat dissipation needs of multiple groups of electric cabinets in series or parallel can be met. By setting multiple filling holes and setting fillers as heat dissipation media inside the filling holes, the thermal efficiency of gas-liquid phase change is further improved. By setting a single-sided hydraulic expansion plate, the problem of filler leakage is effectively avoided.

[0007] Furthermore, the single-sided hydraulic expansion plate is internally provided with equidistantly arranged sealing strips through grooves, the sealing strips respectively correspond to the positions of the packing holes, and the back side of each sealing strip contacts the front side of the low-temperature phase change refrigeration module.

[0008] Through the above solution, the sealing strip can optimize the sealing effect of the packing hole and prevent the packing from leaking easily.

[0009] Furthermore, four bolts are slidably inserted inside the single-sided hydraulic expansion plate, and the outer circumferential surface of each of the bolts is connected to the internal thread of the low-temperature phase change refrigeration module.

[0010] Through the above solution, the single-sided hydraulic expansion plate is connected and fixed to the low-temperature phase change refrigeration module by bolts, which facilitates the installation and disassembly of the single-sided hydraulic expansion plate.

[0011] Furthermore, a support plate is fixedly connected to the front of the rear door of the electric cabinet, and the upper surface of the support plate is in contact with the bottom surface of the shell.

[0012] Through the above solution, the low-temperature phase change refrigeration module is supported by the support plate, thereby increasing the stability of the low-temperature phase change refrigeration module.

[0013] Furthermore, two mounting plates are fixedly connected to both sides of the shell, and the outer surfaces of the mounting plates are slidably connected to the side plates through empty grooves opened inside the side plates.

[0014] Through the above solution, the mounting plate can assist in the installation of the low-temperature phase change refrigeration module, while also increasing the stability of the low-temperature phase change refrigeration module.

[0015] Furthermore, four positioning holes are provided inside the shell, and the outer circumferential surface of the positioning rod is slidably plugged into the shell through the positioning holes.

[0016] Through the above solution, the housing can be positioned through the positioning rods and the positioning holes, thereby facilitating the installation and disassembly of the low-temperature phase change refrigeration module.

[0017] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each control rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the side plate.

[0018] Through the above solution, the control rod is restricted to prevent the control rod from sliding and deviating, thereby increasing the stability of the control rod movement.

[0019] Furthermore, two limit plates are fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of each limit plate is slidably connected to the side plate through a hollow groove opened inside the side plate.

[0020] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, so that the positioning rod is always moved laterally.

[0021] Furthermore, the filler is a porous filler, and the outer surface of the filler is coated with a thermal conductive material.

[0022] Through the above scheme, the porous filler has a high specific surface area and good thermal conductivity, which can effectively improve the thermal efficiency of gas-liquid phase change. The thermal conductive material can fill the microscopic gaps on the surface of the filler and improve the thermal conductivity of the filler, thereby enhancing the heat dissipation effect. At the same time, the thermal conductive material also has good corrosion resistance and stability, which can extend the service life of the filler.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The intelligent electric cabinet heat dissipation system based on phase change refrigeration greatly reduces the heat dissipation energy consumption of the intelligent electric cabinet by setting a low-temperature phase change refrigeration module and adopting phase change refrigeration technology, while improving the heat dissipation effect and being able to meet the heat dissipation requirements of multiple groups of electric cabinets in series or parallel. By setting multiple filling holes and setting fillers as heat dissipation media inside the filling holes, the gas-liquid phase change thermal efficiency is further improved. By setting a single-sided hydraulic expansion plate, the problem of filler leakage is effectively avoided, and the problems of high heat dissipation energy consumption and poor effect of intelligent electric cabinets and difficulty in achieving heat dissipation of multiple groups of electric cabinets in series or parallel are solved.

[0042] It should be noted that a hand wheel is provided on the outer circumferential surface of the control rod 14 , and the control rod 14 can be controlled by the hand wheel.

[0043] The working principle of the above embodiment is:

[0044] The low-temperature phase change refrigeration module 2 is installed on the rear door 1 of the electric cabinet. The temperature sensor 6 can monitor the internal temperature of the electric cabinet in real time and transmit the data to the controller 7. The controller 7 automatically adjusts the working state of the low-temperature phase change refrigeration module 2 according to the temperature change to achieve more accurate temperature control. The low-temperature phase change refrigeration module 2 is the main carrier of heat dissipation. Through the phase change refrigeration technology and the filler 4 as the heat dissipation medium, it can absorb heat when the temperature inside the electric cabinet rises, ensuring that the temperature of the electric cabinet is always at the temperature point of phase change, thereby achieving low-temperature heat dissipation. The filler 4 with a large number of fillers has a high specific surface area and good thermal conductivity, which can effectively improve the thermal efficiency of gas-liquid phase change. The single-sided hydraulic expansion plate 5 adopts It is made of high-strength material, has good sealing and pressure resistance, and ensures that the filler 4 does not leak. The low-temperature phase change refrigeration module 2 is an independent unit with independent refrigeration capacity and temperature control capabilities. It can be flexibly combined and expanded according to actual needs, which not only facilitates the maintenance and replacement of the low-temperature phase change refrigeration module 2, but also meets the heat dissipation requirements of multiple groups of electrical cabinets in series or parallel. When the low-temperature phase change refrigeration module 2 needs to be disassembled and maintained, the control rod 14 can be rotated to drive the positioning rod 15 to move outward, prompting the positioning rod 15 to move out from the positioning hole 16 to cancel the positioning restriction on the outer shell 10, and then the low-temperature phase change refrigeration module 2 can be removed from the support plate 11 for maintenance.
