Technical Field

[0001] This utility model relates to the field of DC power supply technology, and in particular to a parallel DC power supply system. Background Technology

[0002] In today's power application field, DC power supply systems are widely used in various industries, such as communications, power, and industrial automation. With continuous technological advancements, the performance requirements for DC power supply systems are also increasing. In applications requiring high power output, multiple DC power supplies are often connected in parallel to meet load demands.

[0003] However, existing parallel DC power supply systems have some shortcomings in terms of heat dissipation and power supply fixing. For example, poor heat dissipation can lead to excessively high DC power supply temperature, affecting its service life and performance stability; and insecure power supply fixing may cause displacement or even damage during transportation or use. Therefore, we propose a parallel DC power supply system to solve the above problems. Utility Model Content

The housing 101 can be ventilated through the ventilation hole 401. At the same time, with the cooperation of the heat dissipation hole 106, the bottom of the DC power supply 105 can be dissipated.

[0028] In this embodiment, the heat dissipation assembly includes guide holes 501, heat sinks 502, and heat absorption plates 503. Multiple guide holes 501 are provided on the inner wall of the housing 101. Heat sinks 502 are slidably installed in the guide holes 501. A heat absorption plate 503 that is in contact with the DC power supply 105 is fixedly installed on one side of the multiple heat sinks 502 located on the same side. The heat absorption plate 503 can absorb the heat generated by the DC power supply 105. The heat absorbed by the heat absorption plate 503 can be dissipated through the heat sinks 502. Multiple compression springs 504 are fixedly installed on one side of the heat absorption plate 503, and one end of the compression spring 504 is fixedly installed on the inner wall of the housing 101. Under the elastic force of the compression spring 504, the compression spring 504 can push the heat absorption plate 503 into close contact with the DC power supply 105.

[0029] In this embodiment, threaded holes 201 are provided on both inner walls of the housing 101. A clamping mechanism for clamping the DC power supply 105 is provided in the threaded holes 201. The clamping mechanism includes a fixing screw 202, a fixing plate 203 and a handwheel 204. The fixing screw 202 is threaded in the threaded hole 201.

When the temperature is high, the controller 702 can start the cooling fan 6 to rotate, which can improve the heat dissipation efficiency of the DC power supply 105.

[0032] The working principle of this utility model is as follows: When the DC power supply 105 is placed on the placement plate 104 inside the housing 101, under the elastic force of the compression spring 504, the compression spring 504 can push the heat absorption plate 503 into close contact with the DC power supply 105. By rotating the handwheel 204 and the fixing screw 202, under the action of the threaded hole 201, the fixing screw 202 can rotate and move at the same time. The fixing screw 202 can move the fixing plate 203 and clamp and fix the DC power supply 105. When the cover plate 102 is installed on the top of the housing 101, the locking screw 302 passes through the corresponding mounting hole 301. The nut 303 is threaded onto the locking screw 302, which can be used to press and fix the cover plate 102. The heat absorption plate 503 can absorb the heat generated by the DC power supply 105. The heat absorbed by the heat absorption plate 503 can be dissipated through the heat sink 502. At the same time, the bottom of the DC power supply 105 can be dissipated through the ventilation hole 401 and the heat dissipation hole 106. The temperature sensor 701 can monitor the temperature inside the housing 101. When the temperature is high, the controller 702 can start the cooling fan 6 to rotate, which can improve the heat dissipation efficiency of the DC power supply 105.
