Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a power cabinet with overheat protection. Background Technology

[0002] According to the patent document with publication number CN220475175U, the patent document describes a system that uses a fan to draw in external air, which can then enter the cabinet through the air outlet and vent. This system can blow air into the cabinet to dissipate heat, improve the cabinet's heat dissipation efficiency, prevent overheating from affecting its use, and filter the air entering the cabinet to prevent external dust from entering, thus protecting the internal structure. The filter can also be easily disassembled for cleaning or replacement.

[0003] The patent document states that after the fan located inside the base introduces air into the cabinet, the air gradually flows upward from the bottom. During the flow, the air first completes heat exchange with the electrical components at the bottom, causing the air temperature to rise. The effect of heat exchange between the heated air and the electrical components at the top is weakened, which is not conducive to the heat dissipation of the electrical components at the top. Utility Model Content

[0004] The purpose of this utility model is to provide an overheat protection type power cabinet to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An overheat protection type power cabinet includes a cabinet, a heat dissipation mechanism, and a mounting mechanism for installing heat dissipation parts according to the requirements of electrical components.

[0007] The heat dissipation mechanism includes a heat pipe for dissipating heat from electrical components, a cold plate for absorbing heat from the heat pipe on one side of the heat pipe, a radiator for dissipating heat on one side of the cold plate, a hot water pipe connected to the top of the cold plate and the top of the radiator, a cold water pipe connected to the bottom of the cold plate and the bottom of the radiator, a water pump on the top of the cabinet, and three fans fixed on the front side of the radiator.

[0008] The mounting mechanism includes a support plate, which is fixed to the other side of the cold plate. Four support frames are provided on the other side of the support plate. Several first limiting plates are inserted into the support frames, and several second limiting plates corresponding to the first limiting plates are inserted into the support plate.

[0009] Preferably, a door is rotatably connected to the front of the box, and a handle is fixed on the other side of the door.

[0010] Preferred configuration: The radiator is fixed to one side of the cabinet, and four support brackets are fixed to the inner wall of the cabinet.

[0011] Preferably, the support plate has several first insertion holes that cooperate with the second limiting plate, and the support frame has several second insertion holes that cooperate with the first limiting plate.

[0012] Preferably, the support frame has several square slots for placing electrical components.

[0013] Preferably, the evaporation end of the heat pipe is fixedly connected to the first limiting plate, and the condensation end of the heat pipe is fixedly connected to the second limiting plate.

[0014] The advantages compared to existing technologies are as follows:

[0015] 1. Heat is absorbed by the electrical components through the evaporation end of the heat pipe and dissipated through the condensation end of the heat pipe. The hot water that has absorbed heat in the cold plate is drawn out by the water pump and enters the hot water pipe and the radiator. The fan blows air on the radiator to dissipate heat, turning the hot water in the radiator into cold water. The cold water enters the cold plate through the cold water pipe, thus forming a heat dissipation cycle and improving the heat dissipation effect.

[0016] 2. The evaporation end of the heat pipe is fixed by the first limiting plate, so that the heat pipe is in stable contact with the electrical components. The condensation end of the heat pipe is fixed by the second limiting plate, so that the heat pipe is in stable contact with the cold plate. The first limiting plate is inserted into the support frame and the second limiting plate is inserted into the support plate, so that the heat pipe can be flexibly adjusted according to the number and position of the electrical components to achieve precise heat dissipation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, an overheat protection type power cabinet includes a housing 1, a heat dissipation mechanism 3, and a mounting mechanism 4 for installing heat dissipation parts according to the requirements of electrical components.

[0031] In this embodiment: the heat dissipation mechanism 3 includes a heat pipe 302 for dissipating heat from electrical components. A cold plate 301 for absorbing heat from the heat pipe 302 is provided on one side of the heat pipe 302. A radiator 303 for dissipating heat is provided on one side of the cold plate 301. The radiator 303 is fixed to one side of the housing 1. A hot water pipe 304 connects the top of the cold plate 301 to the top of the radiator 303, and a cold water pipe 305 connects the bottom of the cold plate 301 to the bottom of the radiator 303. A water pump 306 is provided on the top of the housing 1. Three fans 307 are fixed to the front of the radiator 303. The heat is dissipated through the heat pipe. The evaporation end of heat pipe 302 absorbs heat from electrical components. The medium at the evaporation end of heat pipe 302 vaporizes and rises. The heat is then conducted out through the condensation end of heat pipe 302, which contacts the cold plate 301. The medium at the condensation end of heat pipe 302 liquefies and falls. The hot water that has absorbed heat in the cold plate 301 is drawn out by water pump 306 and enters the hot water pipe 304 and the radiator 303. The fan 307 blows air into the radiator 303 to dissipate heat, turning the hot water in the radiator 303 into cold water. The cold water enters the cold plate 301 through the cold water pipe 305, thus forming a heat dissipation cycle.

[0032] In this embodiment: the mounting mechanism 4 includes a support plate 401, which is fixed to the other side of the cold plate 301. Four support frames 402 are provided on the other side of the support plate 401, and these four support frames 402 are fixed to the inner wall of the housing 1. Each support frame 402 has several square slots for placing electrical components. Several first limiting plates 403 are inserted into each support frame 402. Several second limiting plates 404 corresponding to the first limiting plates 403 are inserted into the support plate 401. Each support plate 401 has several first insertion holes that mate with the second limiting plates 404, and each support frame 402 has several second insertion holes that mate with the first limiting plates 403. The housing... A door 2 is rotatably connected to the front side of the enclosure, and a handle is fixed to the other side of the door 2. The evaporation end of the heat pipe 302 is fixedly connected to the first limiting plate 403, and the condensation end of the heat pipe 302 is fixedly connected to the second limiting plate 404. The evaporation end of the heat pipe 302 is fixed by the first limiting plate 403, so that the heat pipe 302 is in stable contact with the electrical components. The condensation end of the heat pipe 302 is fixed by the second limiting plate 404, so that the heat pipe 302 is in stable contact with the cold plate 301. The first limiting plate 403 is inserted into the support frame 402, and the second limiting plate 404 is inserted into the support plate 401, so that the heat pipe 302 can be flexibly adjusted according to the number and position of the electrical components, and the heat dissipation is precise.

[0033] Working principle: According to the pre-positioned location of the electrical components, the condensing end of the second limiting plate 404 and the heat pipe 302 are inserted into the second socket through the first socket, with the condensing end of the heat pipe 302 contacting the cold plate 301. The evaporating end of the first limiting plate 403 and the heat pipe 302 is inserted into the first socket. The electrical components are placed in the square slot, making contact with the evaporating end of the heat pipe 302. After the electrical components start operating, the evaporating end of the heat pipe 302 absorbs the heat generated by the electrical components. The medium at the evaporation end vaporizes and rises to the condensation end. The condensation end of the heat pipe 302 contacts the cold plate 301 and conducts heat away. The medium at the condensation end of the heat pipe 302 liquefies and falls back to the evaporation end. The water pump 306 extracts the hot water that has absorbed heat from the cold plate 301. The hot water enters the radiator 303 through the hot water pipe 304. The fan 307 blows air onto the radiator 303 to dissipate heat, causing the hot water in the radiator 303 to turn into cold water. The cold water enters the cold plate 301 through the cold water pipe 305, forming a heat dissipation cycle.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
