Description

Technical Field

[0001] This utility model relates to a power supply box, and more particularly to a temperature control power supply box, belonging to the field of power control. Background Technology

[0002] In modern electronic devices, power supply boxes, as core components providing a stable power supply, are widely used in many fields such as computers, communication base stations, industrial automation equipment, and medical instruments. Their stability and reliability directly determine the normal operation of the powered equipment. For example, in communication base stations, a stable power supply ensures continuous signal transmission; a power failure could lead to widespread communication outages. While existing temperature-controlled power supply boxes generally meet daily usage needs, some shortcomings still require improvement.

[0003] Traditional power supply boxes widely used in the market often lack precise temperature monitoring methods and cannot obtain temperature data of various internal parts in real time. Even if some power supply boxes are equipped with temperature sensors, they simply issue an alarm when the temperature exceeds a certain set threshold and are easily affected by interference from the internal circuitry of the device, resulting in excessively long response times. To address these issues, we propose a temperature-controlled power supply box. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a temperature control power supply box to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A temperature control power supply box includes a power supply box housing. A circuit breaker is installed at the front end of the power supply box housing. The power supply box housing has a first chamber and a second chamber separated from each other. A temperature control module and a solid-state relay are installed in the first chamber. A fuse is installed at the left end of the solid-state relay. Multiple filters are installed in the second chamber. Multiple wiring ports are installed at the bottom rear end of the power supply box housing. A DC power interface and a three-phase power interface are respectively provided on both sides of the upper end of the wiring ports. A heat dissipation window is provided on the right side of the power supply box housing. At least one cooling fan is installed in the heat dissipation window. A filter screen is installed at the end of the heat dissipation window away from the power supply box housing. A frame is provided outside the filter screen. Two sets of insertion holes are opened at the end of the heat dissipation window facing the filter screen. Two sets of plug plates are installed at the end of the filter screen facing the heat dissipation window. The two sets of plug plates are respectively inserted and cooperated with the two sets of insertion holes on the heat dissipation window.

[0008] In one embodiment, both sets of sockets are provided with quick-release components.

[0009] Furthermore, the quick-release assembly includes a movable inner cavity opened in the socket, two sets of movable blocks disposed in the movable inner cavity, and a locking post fixed to one end opposite to the two sets of movable blocks. Push blocks are installed on the outer wall of the two sets of movable blocks away from the heat dissipation window. A return spring is provided between the two sets of movable blocks. The upper and lower sides of the inner wall of the socket are provided with locking slots, and the locking posts of the two sets can be inserted into the two sets of locking slots.

[0010] In one embodiment, the output terminal of the temperature control module and the input terminal of the solid-state relay are connected by a signal line.

[0011] In one embodiment, the temperature control module is provided with multiple sets of temperature sensors and a signal processing module, and the temperature sensors are connected to the analog input terminals of the temperature control module.

[0012] In one embodiment, the wiring port uses multiple RS485 interfaces.

[0013] In one embodiment, a human-machine interface panel is installed at the lower end of the circuit breaker, and the input terminal of the human-machine interface panel is electrically connected to the internal components of the power supply box housing.

[0014] In one embodiment, multiple temperature control modules within the temperature control module correspond to an independent temperature control loop, and each loop controls a fuse via a solid-state relay.

[0015] In one embodiment, multiple filters within the second chamber are directly connected to a DC power interface via wiring.

[0016] In one embodiment, nine sets of filters are symmetrically arranged in the second chamber.

[0017] After adopting the above technical solution, this utility model has at least the following beneficial effects:

[0018] 1. By setting a first chamber and a second chamber inside the power supply box housing, this dual-chamber design can separate the filter from the temperature control module and the solid-state relay. This not only facilitates the later maintenance of the overall equipment, but also avoids interference between equipment signals and reduces the difficulty of wiring. Furthermore, the direct cooperation between the temperature control module and the solid-state relay can effectively improve the response speed of the equipment.

[0019] 2. By installing a human-machine interface panel on the outside of the equipment, the temperature parameters can be set and monitored directly by operating the human-machine interface panel. The human-machine interface panel can display the temperature parameters in real time, which is convenient for external observation and ensures that the equipment can operate stably.

[0020] 3. By installing at least one set of cooling fans on the side of the power supply box housing, the internal temperature of the power supply box housing can be effectively reduced, thereby effectively improving the heat dissipation effect of the device. Furthermore, by installing a removable filter screen on the outside of the heat dissipation window, the filter screen can isolate the floating lint in the air entering the power supply box housing, ensuring that at least one set of cooling fans can effectively dissipate heat from the inside of the power supply box housing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0033] Figures 1 to 7As shown, this embodiment provides a temperature control power supply box, including a power supply box housing 1. A circuit breaker 2 is installed at the front end of the power supply box housing 1. The power supply box housing 1 has a first chamber 9 and a second chamber 10 that are separated from each other. A temperature control module 3 and a solid-state relay 4 are installed in the first chamber 9. A fuse 12 is provided at the left end of the solid-state relay 4. Multiple sets of filters 5 are provided in the second chamber 10. Multiple sets of wiring ports 6 are installed at the bottom of the rear end of the power supply box housing 1. A DC power interface 7 and a three-phase power interface 11 are respectively provided on both sides of the upper end of the wiring ports 6.

[0034] The temperature control power supply box circuit breaker 2 is used for overload protection, filter 5 is used to eliminate power supply noise, and fuse 12 provides additional overcurrent protection. The 9-channel temperature control module 3 may control the temperature of fuse 12 through multiple temperature controllers and solid-state relays 4. Filter 5 is connected to the input terminal of DC power interface 7, and then passes through fuse 12 and power box housing 1 before being distributed to multiple temperature control modules in temperature control module 3. Each temperature control module corresponds to an independent temperature control loop, and each loop controls fuse 12 through solid-state relay 4, thereby ensuring that the equipment can operate normally. Furthermore, by setting a first chamber 9 and a second chamber 10 in the power box housing 1, this dual-chamber design can separate filter 5 from temperature control module 3 and solid-state relay 4, which not only facilitates the later maintenance of the overall equipment, but also avoids interference between equipment signals and reduces the difficulty of wiring.

[0035] A heat dissipation window 13 is provided on the right side of the power supply box housing 1. At least one set of cooling fans 14 is installed inside the heat dissipation window 13. A filter screen 15 is installed at the end of the heat dissipation window 13 away from the power supply box housing 1. A frame 16 is provided outside the filter screen 15. Two sets of insertion holes 17 are opened at the end of the heat dissipation window 13 facing the filter screen 15. Two sets of insertion plates 18 are installed at the end of the filter screen 15 facing the heat dissipation window 13. Both sets of insertion plates 18 can be inserted into the two sets of insertion holes 17 on the heat dissipation window 13. Quick-release components are provided in both sets of insertion holes 17.

[0036] By installing at least one set of cooling fans 14 on the side of the power supply housing 1, the temperature inside the power supply housing 1 can be effectively reduced, thereby improving the heat dissipation effect of the device. Furthermore, by installing a removable filter screen 15 on the outside of the heat dissipation window 13, the filter screen 15 can isolate the floating lint in the air entering the power supply housing 1, ensuring that at least one set of cooling fans 14 can effectively dissipate heat from the inside of the power supply housing 1.

[0037] In some more specific implementations, the quick-release assembly includes a movable inner cavity 19 opened in the socket 17, two sets of movable blocks 20 disposed in the movable inner cavity 19, and locking posts 21 fixed to the opposite ends of the two sets of movable blocks 20. Push blocks 22 are installed on the outer wall of the end of the two sets of movable blocks 20 away from the heat dissipation window 13. A return spring 23 is provided between the two sets of movable blocks 20. The upper and lower sides of the inner wall of the socket 17 are provided with locking slots 24, and the two sets of locking posts 21 can be inserted into the two sets of locking slots 24.

[0038] When the filter screen 15 needs to be disassembled and cleaned, the two sets of push blocks 22 in the two sets of insert plates 18 can be pushed in opposite directions, so that the two sets of movable blocks 20 in the insert plates 18 can move in opposite directions. When the two sets of locking posts 21 are completely separated from the two sets of locking slots 24 in the insertion holes 17, and the two sets of movable blocks 20 press against the return spring 23, the sleeve frame 16 can then drive the two sets of insert plates 18 to be pulled out from the two sets of insertion holes 17. When the filter screen 15 needs to be installed, the above operation is repeated in reverse to complete the installation of the filter screen 15.

[0039] In some more specific implementations, the output of the temperature control module 3 and the input of the solid-state relay 4 are connected by a signal line. Since both the temperature control module 3 and the solid-state relay 4 are located inside the first chamber 9, using a signal line for connection can effectively avoid the problem of signal attenuation caused by excessively long cables.

[0040] In some more specific implementations, the temperature control module 3 is equipped with multiple sets of temperature sensors and a signal processing module. The temperature sensors are connected to the analog input terminals of the temperature control module 3. The signal processing module amplifies and filters the input signal to ensure correct signal output, converts the analog signal into a digital signal, and then compares the set value with the actual value. Based on the set value, the temperature control module 3 adjusts the on / off state of the solid-state relay 4 to control the power supply of the load.

[0041] In some more specific implementations, the wiring port 6 uses multiple RS485 interfaces. This design allows the power supply housing 1 to communicate with a host computer or other control units via the RS485 interface.

[0042] In some more specific implementations, a human-machine interface panel 8 is installed at the lower end of the circuit breaker 2, and the input terminal of the human-machine interface panel 8 is electrically connected to the internal components of the power supply box housing 1.

[0043] Temperature parameters can be set and monitored by operating the human-machine interface panel 8, and the human-machine interface panel 8 can display the temperature parameters in real time, making it easy for the outside world to observe them directly.

[0044] In some more specific implementations, multiple temperature control modules within the temperature control module 3 correspond to an independent temperature control loop, and each loop controls the fuse 12 via a solid-state relay 4.

[0045] When any one of the multiple temperature control modules senses an abnormal temperature, it can send an electrical signal to cause the solid-state relay 4 to control the fuse 12 to disconnect the circuit.

[0046] In some more specific implementations, multiple sets of filters 5 within the second chamber 10 are directly wired to the DC power interface 7. This design allows the filters 5 to eliminate power noise from the incoming current to the DC power interface 7 immediately.

[0047] All electrical components mentioned in this manual are electrically connected to an external main controller and industrial power supply. The main controller can be a conventional known device such as a computer that provides control.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
