Description

Technical Field

[0001] This utility model relates to the field of transformer heat dissipation technology, specifically to a fastening structure for a transformer plate heat sink. Background Technology

[0002] Transformer plate radiators are important components of transformers. They are usually made of materials with excellent heat dissipation properties, such as aluminum or copper. Their working principle is to use the natural convection of oil or cold air to carry the heat generated by the transformer to the tank wall surface and heat dissipation pipes, and then dissipate the heat through air convection and heat conduction, thereby reducing the operating temperature of the transformer.

[0003] When installing plate-type radiators on the outside of a transformer, multiple sets of radiators are usually installed on each side of the transformer. However, the radiators are large in size and are not easy to position and align during installation. Therefore, a fastening structure for transformer plate-type radiators is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: the heat sink is large in size and is not easy to position and align during installation.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A fastening structure for a transformer finned radiator includes a radiator body, a fastening mechanism located below the radiator body, a support mechanism located on the side of the fastening mechanism, and an outer frame for the radiator body, wherein a plurality of heat dissipation fins are fixedly installed on the inner side of the outer frame.

[0007] The support mechanism includes a flip plate, and connecting shafts are symmetrically fixedly connected to both sides of the upper end of the flip plate. Blind holes are opened at the top of both connecting shafts.

[0008] The flip plate has a hollow center and several support pads are fixedly installed at the lower end of the flip plate. Each support pad is arranged at equal intervals along the bottom edge of the flip plate.

[0009] The lower inner wall of the flip plate is fixedly installed with a water supply pipe. Both ends of the water supply pipe extend to the outside of the flip plate, and both ends of the water supply pipe are fixedly connected with connectors. Several extension pipes are connected through the side of the water supply pipe and near each support pad. The end of the extension pipe passes through the middle of the surface of the support pad. Spray nozzles are fixedly connected around the end of the extension pipe away from the support pad.

[0010] As a further embodiment of this utility model: the fastening mechanism includes a shelf, a flow guide is provided in the middle of the bottom surface of the shelf, and connecting holes are symmetrically provided on both sides of the back of the shelf. Support legs are symmetrically and fixedly connected to the bottom surface of the shelf.

[0017] (1) The present invention provides a fastening mechanism at the bottom of the radiator body. The fastening mechanism is connected to the bottom surface through the support leg and supported by the shelf above. After the fastening mechanism is fixed to the outside of the transformer through the connecting hole on the surface, the radiator can be erected on the fastening mechanism.

Spray nozzles 308 are fixedly connected around the end of the extension pipe 307 away from the support pad 304. Figures 4-5 As shown, each nozzle 308 faces the heat sink 102;

[0030] The fastening mechanism 2 includes a shelf 201. A flow guide 202 is provided in the center of the bottom surface of the shelf 201. Connecting holes 207 are symmetrically provided on both sides of the back of the shelf 201. Support legs 208 are symmetrically fixedly connected to the bottom surface of the shelf 201. A first mating member 203 is symmetrically fixedly connected to one side of the bottom surface of the shelf 201, and a second mating member 204 is symmetrically fixedly connected to the other side of the top surface of the shelf 201. The inner side of the middle of the second mating member 204 is movably inserted into the first mating member 203. Figure 1 As shown, adjacent shelves 201 are connected to each other via a first connecting member 203 and a second connecting member 204;

[0031] A bolt 205 is threaded through the center of the surface of the second mating member 204, and the bolt 205 is threaded through the center of the first mating member 203. The top of the bolt 205 extends above the second mating member 204, and a nut 206 is threaded onto the top of the bolt 205. Bearing sleeves 209 are symmetrically fixed to both sides of the front of the shelf 201. Each bearing sleeve 209 has a through-hole 210 on its bottom surface.

[0034] The working principle of this utility model:

[0035] When installing the radiator body 1, first attach the shelf 201 tightly to the installation point on the outer wall of the transformer, and fix the shelf 201 to the outer wall of the transformer by passing the screw through the connecting hole 207. Insert the first mating piece 203 on the side of the adjacent shelf 201 into the inside of the second mating piece 204, and then tighten the nut 206 to lock it by passing the bolt 205 through.

[0036] Next, the radiator body 1 is placed on the shelf 201 to provide stable support for the radiator body 1, which facilitates the subsequent installation with the transformer. After installation, the shelf 201 is rotated in the direction of the radiator body 1, so that the support pad 304 is inserted between each heat sink 102. At the same time, the nozzle 308 also follows the support pad 304 into the gap of the heat sink 102. The spring 213 lifts the pin 212, so that its end is inserted into the blind hole 303, thereby fixing the flip plate 301. Then, the external coolant pipeline is connected to each water supply pipe 305. The coolant is sprayed onto the heat sink 102 through the nozzle 308. The coolant falls back to the ground through the guide port 202 at the bottom of the shelf 201 to avoid coolant accumulation.
