Description

Technical Field

[0001] This application relates to the field of cooling fan technology, and more specifically, to a cooling fan for transformer heat dissipation. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions of a transformer include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). According to its application, it can be divided into power transformers and special transformers.

[0003] Transformers generate heat during operation. If the heat is too high, the transformer is prone to failure. Therefore, we need to dissipate heat. Currently, some transformers dissipate heat by installing a cooling fan on one side. The cooling fan will suck in some dust and debris when it is working, so it is necessary to disassemble and clean the cooling fan regularly. However, the existing cooling fans are fixed to the side of the transformer with bolts, which is troublesome when disassembling them.

[0004] Therefore, a cooling fan for transformer heat dissipation that is easy to disassemble is provided. Utility Model Content

[0033] Reference Figure 1-6 A cooling fan 100 for transformer heat dissipation includes: a housing 101, a fixing frame 102, a motor 103, a connecting block 104, fan blades 105, a protective frame 106, a fixing assembly for fixing the fixing frame 102 to the housing 101, and a disassembly assembly for fixing the fixing frame 102 to the housing 101. The fixing frame 102 is located on one side of the housing 101. The motor 103 is fixedly connected to the fixing frame 102. The connecting block 104 is fixedly connected to the drive shaft of the motor 103. The fan blades 105 are fixedly connected to the connecting block 104. The protective frame 106 is fixedly connected to the fixing frame 102.

[0034] The fixing assembly, used to fix the fixing frame 102 to the housing 101, includes: a first slider 107, a first spring 108, a connecting plate 109, and a locking block 110. The first slider 107 is slidably connected to the fixing frame 102. Specifically, the fixing frame 102 is provided with a first groove 102a extending along the length direction of the fixing frame 102, and the first slider 107 moves along the first groove 102a. The two ends of the first spring 108 are fixedly connected to the first slider 107 and the fixing frame 102, respectively. The connecting plate 109 is fixedly connected to the first slider 107.

[0035] The transmission block 114 is located at one end of the first slider 107, and the first spring 108 is located at the other end of the first slider 107. The locking block 110 is fixedly connected to the connecting plate 109. The housing 101 includes a locking groove 101a, and the locking block 110 engages with the locking groove 101a. The fixing frame 102 is provided with a clearance groove 102b, through which the connecting plate 109 passes, and with a gap between the clearance groove 102b and the connecting plate 109. The first spring 108 is located within the first sliding groove 102a.

[0036] The disassembly assembly, used to disassemble the mounting bracket 102 from the housing 101, includes: a first slip ring 112, a drive block 113, and a transmission block 114. The first slip ring 112 is horizontally slidably connected to the housing 101. Specifically, the housing 101 has a second slide groove 101b extending axially along the housing 101, and the first slip ring portion is located within the second slide groove 101b and moves along the second slide groove 101b. The drive block 113 is fixedly connected to the first slip ring 112. The transmission block 114 is fixedly connected to the first slider 107. The drive block 113 includes a drive inclined surface 113a, and the transmission block 114 includes a transmission inclined surface 114a, with the drive inclined surface 113a abutting against the transmission inclined surface 114a.

[0037] The mounting bracket 102 includes a guide hole 102c, and a transmission block 114 is partially located within the guide hole 102c, with the transmission block 114 guided through the guide hole 102c. When cleaning is required, the first slip ring 112 is pushed, causing the first slip ring 112 to move and drive the drive block 113 to move. The drive block 113, through the drive inclined surface 113a and the transmission inclined surface 114a, drives the transmission block 114 to move. The movement of the transmission block 114 causes the first slider 107 to move, which in turn causes the connecting plate 109 to move. The movement of the connecting plate 109 causes the locking block 110 to move, disengaging the locking block 110 from the restriction of the slot 101a. This allows the motor 103, protective cover, and fan blade 105 to be disassembled and cleaned, making disassembly more convenient.

[0038] Workflow: In use, the housing 101 is fixed to one side of the transformer. Then, the motor 103 drives the connecting block 104 to rotate, which in turn drives the fan blade 105 to rotate, thereby dissipating heat from the transformer. When long-term use requires cleaning of the inside of the housing 101 and the fan blade 105, the first slip ring 112 is pushed. The movement of the first slip ring 112 drives the drive block 113 to move. The drive block 113, through the drive inclined surface 113a and the transmission inclined surface 114a, drives the transmission block 114 to move. The movement of the transmission block 114 drives the first slider 107 to move. The movement of the first slider 107 drives the connecting plate 109 to move. The movement of the connecting plate 109 drives the locking block 110 to move, causing the locking block 110 to disengage from the slot 101a. This allows the motor 103, the protective cover, and the fan blade 105 to be disassembled and cleaned, making disassembly more convenient.
