Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to a heat dissipation type transformer rectifier switching power supply. Background Art

[0002] A transformer-rectifier is a power electronic device that converts AC power to DC power, combining the functions of a transformer and a rectifier. Specifically, it first uses a transformer to step up or down the AC voltage, and then uses a rectifier circuit to convert the transformed AC power to DC power. A switching power supply is typically installed within the transformer-rectifier to improve energy efficiency, precisely regulate voltage, and achieve miniaturization and lightweighting.

[0003] For example, a Chinese patent discloses: an LED switching power supply with efficient heat dissipation, patent number: CN211352025U, which increases the heat dissipation area by heat dissipation fins to achieve cooling and heat dissipation; the automatic heat dissipation device can monitor the internal temperature of the switching power supply in real time through a temperature detector. When the temperature reaches a high value, the first cooling fan and the second cooling fan are automatically turned on to achieve rapid heat dissipation, temperature control and efficient heat dissipation.

[0004] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: the above device dissipates heat for the switching power supply by installing multiple cooling fans, but the cooling fans in the above device are installed relatively fixedly and lack a sliding and fitting function. In order to reserve space for the switching power supply installation, a certain distance needs to be maintained between the cooling fan and the switching power supply. This distance will reduce the efficiency of air flow, thereby affecting the heat dissipation function. Utility Model Content

In order to reserve space for the switching power supply installation, a certain distance needs to be maintained between the cooling fan and the switching power supply. This distance will reduce the efficiency of air flow, thereby affecting the heat dissipation function.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A heat dissipation transformer rectifier switching power supply includes a transformer rectifier body, a handle rod is rotatably connected inside the transformer rectifier body, a first connecting rod is sleeved on the outer surface of the handle rod, and two second connecting rods are rotatably connected to the outer surface of the first connecting rod. Two sliders are slidably connected inside the transformer rectifier body, and the two second connecting rods are respectively rotatably connected inside the two sliders. The upper ends of the two sliders are fixedly connected to a group of fan bodies, and the upper ends of the two sliders are fixedly connected to a clamping mechanism. The clamping mechanism includes two clamping blocks, and the two clamping blocks are respectively fixedly connected to the upper ends of the two sliders.

[0010] Preferably, a switching power supply body is movably connected inside the transformer rectifier body, and a heat dissipation hole is provided inside the switching power supply body.

[0011] Preferably, heat dissipation fins are fixedly connected to both sides of the switching power supply body.

[0012] Preferably, two sets of slide rails are fixedly connected inside the transformer rectifier body, and a set of slide grooves are provided inside the two sliders.

[0013] Preferably, a ratchet is sleeved on the outer surface of the handle rod.

[0014] Preferably, a ratchet is rotatably connected inside the transformer rectifier body.

[0015] (3) Beneficial effects

[0016] 1. After the switching power supply body is placed inside the transformer rectifier body, the handle rod is screwed to drive the first connecting rod to rotate counterclockwise through the handle rod. The first connecting rod drives the two sliders to slide inward through the two second connecting rods. The two sliders drive the two clamps to slide to clamp and fix the switching power supply body. During the sliding process, the two fan bodies are driven to slide and fit the switching power supply body, shortening the distance between the fan body and the switching power supply body, ensuring that the fan body can most effectively cool the heat source part of the switching power supply body, which is conducive to improving the flexibility of the device and improving the heat dissipation efficiency.

[0017] 2. The handle rod drives two clamps to clamp the switching power supply body to ensure that it is stably placed in the transformer rectifier body. When the handle rod rotates, the ratchet is driven to rotate and is limited by the pawl to prevent reverse rotation. When the switching power supply body needs to be removed for maintenance or replacement, the pawl is pressed to release the squeeze limit of the ratchet. At this time, the handle rod can be turned clockwise to loosen the fixed clamp on the switching power supply body and it can be taken out for maintenance, which simplifies the work process, improves the disassembly efficiency, and is conducive to improving the convenience of maintenance and disassembly operations.

When the handle rod 12 rotates, it drives the ratchet 24 to rotate and is limited by the pawl 25 to avoid reverse rotation.
