Description

Technical Field

[0001] This application relates to the field of transformer technology, specifically a transformer cooling device for data centers. Background Technology

[0002] Transformer cooling systems are crucial equipment for ensuring transformers operate within a reliable and safe temperature range. Their primary function is to transfer heat away from the transformer to maintain its normal operating temperature and extend its service life. Transformer cooling systems primarily operate through two methods: natural cooling and forced cooling.

[0003] When a transformer is being cooled naturally, its temperature may rise abnormally due to malfunctions. In this case, in order to cool it down quickly, maintenance personnel will usually send a maintenance team with equipment to perform auxiliary forced cooling on the transformer's heat sink. A common method of auxiliary forced cooling is to pour water on the transformer's heat sink. However, this method is inefficient and requires continuous operation by personnel, which is time-consuming and labor-intensive.

[0004] Therefore, this application provides a transformer cooling device for data centers to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a transformer cooling device for data centers, aiming to solve the problem mentioned in the background art that when transformers are naturally cooled, abnormal operation sometimes causes the transformer temperature to rise abnormally. In this case, in order to cool down quickly, maintenance personnel usually send maintenance teams with equipment to perform auxiliary forced cooling on the transformer shell heat sink. A common auxiliary forced cooling method is to pour water on the transformer heat sink. However, this method is inefficient, requires continuous operation by personnel, and is time-consuming and labor-intensive.

[0006] To achieve the above objectives, this application provides the following technical solution: a transformer cooling device for data centers, comprising a cooling rack fixedly mounted on the transformer housing for auxiliary cooling of a heat sink fixedly mounted on the transformer housing.

[0007] The cooling rack has two symmetrically arranged first sliding grooves. A first motor is fixedly installed at one end of one of the first sliding grooves. A first lead screw, extending into the first sliding groove and rotatably connected to the cooling rack, is fixedly installed at the output end of the first motor. A spray frame is screwed onto the first lead screw. A water supply pipe connected to a water source is fixedly installed on the side of the spray frame away from the heat sink. Two symmetrically arranged nozzles are fixedly installed on the side of the spray frame facing the heat sink. Thus, during heat dissipation, starting the first motor drives the first lead screw to rotate, which in turn causes the spray frame to slide left and right on the cooling rack. The water supply pipe is connected to a water source, and cold water is sprayed out through the nozzles to assist in cooling the transformer casing and the outer wall of the heat sink. This process requires no manual operation, resulting in higher efficiency and more timely heat dissipation.

[0008] Preferably, to distribute the water source, a water cavity is provided inside the spray frame, and the water cavity is connected to the water supply pipe and the spray head. This ensures that the sprayed water is evenly distributed.

[0009] Preferably, to support the spray frame, a first slide rod symmetrically arranged with the first lead screw is fixedly installed in another of the first slide grooves, and the end of the spray frame away from the first lead screw is slidably installed on the first slide rod. This ensures stable sliding of the spray frame.

[0010] Preferably, for temperature monitoring, an infrared temperature sensor is fixedly installed on the cooling rack, with the sensor's detection end facing the heat sink. This facilitates control.

[0011] Preferably, for cleaning the heat sink, the cooling device further includes a cleaning mechanism. The cleaning mechanism comprises two symmetrically arranged slots fixedly mounted on the cooling rack between the spray rack and the heat sink. A second motor is fixedly mounted at one end of one of the slots, and a second lead screw extending into and rotatably connected to the slot is fixedly mounted on the output end of the second motor. A horizontal plate is screwed onto the second lead screw. A second slide rod is fixedly mounted inside the other slot, and the other end of the horizontal plate is slidably mounted on the second slide rod. A brush plate facing the outer wall of the heat sink is provided on the horizontal plate. This removes floating dust and oil film, ensuring the surface of the heat sink is clean and guaranteeing its heat dissipation efficiency.

[0012] Preferably, for the purpose of replacing the brush plate, the brush surface of the brush plate is positioned to contact the heat sink, and bolts penetrating the horizontal plate are screwed onto the brush plate. This facilitates the replacement and maintenance of worn brush plates.

[0013] The cooling device starts with a first motor, which drives a first lead screw to rotate. The lead screw then moves a spray frame left and right on the cooling frame. The water supply pipe is connected to an external water source, and cold water is sprayed out through the nozzles to provide auxiliary cooling for the transformer casing and the outer wall of the heat sink. It requires no manual operation, is more efficient, and provides more timely heat dissipation.

[0014] The cooling device starts with a second motor, which drives a second lead screw to rotate. The lead screw then moves a horizontal plate up and down within two slots, and a brush plate on the horizontal plate cleans the surface of the heat sink, scraping away dust and oil film to ensure the surface of the heat sink is clean and to guarantee its heat dissipation efficiency.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a transformer cooling device for data centers, such as... Figure 1-4 As shown, the cooling device includes a cooling rack 3 fixedly mounted on the transformer housing 1 for auxiliary cooling of the heat dissipation plate 2 fixedly mounted on the transformer housing 1.

[0024] Two first sliding grooves 31 are symmetrically opened on the cooling rack 3. A first motor 32 is fixedly installed at one end of one of the first sliding grooves 31. A first lead screw 33 extending into the first sliding groove 31 and rotatably connected to the cooling rack 3 is fixedly installed on the output end of the first motor 32. A spray rack 34 is screwed onto the first lead screw 33. A water supply pipe 35 connected to the water source is fixedly installed on the side of the spray rack 34 away from the heat sink 2. Two symmetrically arranged spray nozzles 36 are fixedly installed on the side of the spray rack 34 facing the heat sink 2.

[0025] When in use, the first motor 32 is started, which drives the first lead screw 33 to rotate. The first lead screw 33 drives the spray frame 34 to slide left and right on the cooling frame 3. The water supply pipe 35 is connected to the water source end, and cold water is sprayed out through the nozzle 36 to assist in cooling the outer wall of the transformer shell 1 and the heat sink 2. No manual operation is required, which is more efficient and heat dissipation is more timely.

[0026] It should be noted that cooling racks 3 are installed on both sides of the transformer housing 1 to dissipate heat from both sides of the transformer housing 1, thereby further improving the heat dissipation efficiency.

[0027] Specifically, a water chamber 37 is provided inside the spray frame 34, and the water chamber 37 is connected to the water supply pipe 35 and the nozzles 36. In use, the water flow input from the water supply pipe 35 is concentrated in the water chamber 37 inside the spray frame 34, thereby spraying water onto the two nozzles 36 and ensuring that the sprayed water flow is evenly distributed.

[0028] More specifically, a first slide rod 38, symmetrically arranged with the first lead screw 33, is fixedly installed in another first slide groove 31. One end of the spray frame 34, away from the first lead screw 33, is slidably installed on the first slide rod 38. In use, when the spray frame 34 slides in the first slide groove 31, the other end is supported by the first slide rod 38 to ensure stable sliding of the spray frame 34.

[0029] Furthermore, an infrared temperature sensor 39 is fixedly installed on the cooling rack 3, with the detection end of the infrared temperature sensor 39 facing the heat sink 2. In use, the infrared temperature sensor 39 detects the temperature change of the heat sink 2. Once the temperature becomes abnormally high, the first motor 32 is activated to provide auxiliary cooling for the heat sink 2, facilitating control.

[0030] Example 2

[0031] Unlike Embodiment 1, the heat sink 2 will accumulate a layer of floating dust and oil film on its surface after long-term use, affecting the heat dissipation effect. Therefore, the cooling device also includes a cleaning mechanism 4. The cleaning mechanism 4 includes two slot plates 41 fixedly installed on the cooling rack 3 and symmetrically arranged between the spray rack 34 and the heat sink 2. A second motor 42 is fixedly installed at one end of one slot plate 41. A second lead screw 43 extending into the slot plate 41 and rotatably connected to the slot plate 41 is fixedly installed at the output end of the second motor 42. A horizontal plate 44 is screwed onto the second lead screw 43. A second slide rod 45 is fixedly installed in the other slot plate 41. The other end of the horizontal plate 44 is slidably installed on the second slide rod 45. A brush plate 46 is provided on the horizontal plate 44 facing the outer wall of the heat sink 2. When in use, start the second motor 42, which drives the second lead screw 43 to rotate. The second lead screw 43 drives the horizontal plate 44 to move up and down within the two slot plates 41. The brush plate 46 on the horizontal plate 44 cleans the surface of the heat sink 2, scraping off the floating dust and oil film to ensure that the surface of the heat sink 2 is clean and to ensure the heat dissipation efficiency of the heat sink 2.

[0032] Furthermore, the brush surface of the brush plate 46 is positioned to contact the heat sink 2, and a bolt 47 is screwed onto the brush plate 46, penetrating the horizontal plate 44. In use, the brush plate 46 is fixed to the horizontal plate 44 by the bolt 47, facilitating the replacement and maintenance of worn brush plates 46.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
