Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency transformers, and in particular to a water-cooled high-frequency transformer. Background Technology

[0002] A high-frequency transformer is a transformer that operates within a relatively high frequency range and is commonly used in switching power supplies, high-frequency induction heating, wireless charging, and other fields. It utilizes high-frequency AC power and achieves voltage transformation and isolation through the principle of electromagnetic induction. It boasts advantages such as small size, light weight, high efficiency, and high power density, making it an indispensable component of modern power electronics technology.

[0003] The prior art discloses a utility model patent entitled "An Integrated High-Frequency Water-Cooled Transformer," with publication number CN219575342U. It includes a thermally conductive silicone sheet, a thermally conductive side plate, a connecting base box, a drain pipe, a water inlet pipe, and a front-end auxiliary filter mechanism connected to the water inlet pipe. The thermally conductive silicone sheet and the thermally conductive side plate are sequentially arranged on opposite sides of the high-frequency transformer, while the connecting base box, drain pipe, and water inlet pipe are located at the bottom of the thermally conductive side plate.

[0004] However, the front-end auxiliary filtration mechanism described in the patent application will become clogged by impurities in the cooling medium after long-term use. Since the filter plates cannot be replaced quickly, the front-end auxiliary filtration mechanism needs to be shut down for maintenance, causing intermittent shutdown of the heat dissipation function. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the front-end auxiliary filtration mechanism requires downtime for maintenance when replacing the filter screen.

[0006] To achieve the above objectives, this application proposes a water-cooled high-frequency transformer, comprising: a transformer body; a water inlet pipe disposed at the bottom of the transformer body and a front-end auxiliary filtration mechanism penetrated by the water inlet pipe; a quick screen changing mechanism disposed on the front-end auxiliary filtration mechanism; wherein, the quick screen changing mechanism comprises: a telescopic mechanism disposed on either the left or right side of the front-end auxiliary filtration mechanism; a filter plate connected to the output end of the telescopic mechanism; the filter plate comprises a first filter plate and a second filter plate arranged sequentially along the telescopic direction of the telescopic mechanism; The first filter plate and the second filter plate are integrally formed.

[0007] The telescopic mechanism of this application drives the filter plate to move in the front-end auxiliary filtration mechanism. When the first filter plate is blocked by impurities in the cooling medium, the telescopic mechanism retracts, driving the first filter plate out of the front-end auxiliary filtration mechanism, and the second filter plate replaces the original position of the first filter plate. Only the cooling medium needs to be filtered. The removed first filter plate can be reused after cleaning. The entire process can be completed without stopping the machine to replace the filter plate, which solves the problem that the machine needs to be stopped for maintenance when replacing the filter screen in the front-end auxiliary filtration mechanism in the prior art.

[0008] Furthermore, the front-end auxiliary filtration mechanism has through slots on both sides perpendicular to the output end of the telescopic mechanism, through which the first filter plate and the second filter plate pass.

[0009] Furthermore, in order to secure the telescopic mechanism, a support frame is provided between the telescopic mechanism and its nearest side.

[0010] Furthermore, to facilitate the positioning of the filter plate during installation, the center lines of the through hole and through groove for the output shaft of the telescopic mechanism on the support frame are on the same axis.

[0011] As an improvement to the filter plate described in this application, in order to better cooperate with the inlet pipe to filter the cooling medium, the filter plate includes: a filter screen portion for filtering the cooling medium and perpendicular to the inlet pipe and having the same cross-sectional shape as the inlet pipe, and a flow-blocking portion covering the filter screen portion.

[0012] Furthermore, to prevent the cooling medium from flowing out of the filter section, the cross-sectional dimension of the filter section is equal to the cross-sectional dimension of the inlet pipe.

[0013] The beneficial effects of this application are as follows: 1. The water-cooled high-frequency transformer of this application, by setting a telescopic mechanism, drives the filter plate to move in the front-end auxiliary filtration mechanism. When the first filter plate is blocked by impurities in the cooling medium, the telescopic mechanism retracts, driving the first filter plate out of the front-end auxiliary filtration mechanism, and the second filter plate replaces the original position of the first filter plate. It only needs to filter the cooling medium. The removed first filter plate can be reused after cleaning. The entire process can be completed without stopping the machine to replace the filter plate, which solves the problem that the machine needs to be stopped for maintenance when replacing the filter screen in the front-end auxiliary filtration mechanism in the prior art.

[0014] 2. This application uses symmetrically arranged through slots and a support frame on one side of the through slot to facilitate the positioning of the telescopic mechanism and the filter plate during installation.

[0015] 3. The filter plate in the quick screen changing mechanism of this application extends and retracts in the vertical direction, which can prevent the filter plate from protruding from the transformer body in the horizontal direction during filter replacement, thus avoiding damage to the filter plate.

[0018] The following will be combined with the appendix Figures 1-2 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Example

[0019] like Figures 1-2 This illustration depicts a water-cooled high-frequency transformer, including a transformer body 1, a water inlet pipe 5 located at the bottom of the transformer body 1, and a front-end auxiliary filtration mechanism 2 penetrated by the water inlet pipe 5. To allow for filter plate replacement without stopping the machine, a quick-change screen mechanism 3 is provided on the front-end auxiliary filtration mechanism 2. This mechanism includes a telescopic mechanism 31 located on either the left or right side of the front-end auxiliary filtration mechanism 2, and a filter plate 32 connected to the output end of the telescopic mechanism 31. The filter plate 32 consists of a first filter plate 321 and a second filter plate 322 arranged sequentially along the telescopic direction of the telescopic mechanism 31, and the first filter plate 321 and the second filter plate 322 are integrally formed.

[0020] Optionally, the telescopic mechanism 31 can be configured as a device with a telescopic rod, such as a hydraulic cylinder, a pneumatic cylinder, or a linear servo motor.

[0021] In the embodiments of this application, when the first filter plate 321 is clogged by impurities in the cooling medium, the telescopic mechanism 31 retracts, causing the first filter plate 321 to exit the front-end auxiliary filtration mechanism 2 along the through groove 21. At this time, the second filter plate 322 automatically replaces the first filter plate 321 to continue filtering the cooling medium. The exited first filter plate 321 can be reused after cleaning. The entire process does not require machine downtime, thus solving the problem in the prior art where machine downtime is required for maintenance when replacing the filter screen in the front-end auxiliary filtration mechanism. This design significantly improves the operating efficiency and reliability of the transformer. Example

[0022] like Figures 1-2 This illustration depicts a water-cooled high-frequency transformer. To facilitate the installation and positioning of the telescopic mechanism and filter plate, and to secure the telescopic mechanism 31 and facilitate the positioning of the filter plate 32 during installation, a support frame 4 is provided between the telescopic mechanism 31 and its nearest side. Furthermore, to facilitate the positioning of the filter plate 32 during installation, the through hole on the support frame 4 for the output shaft of the telescopic mechanism 31 is aligned with the centerline of the through slot 21. This design not only improves installation efficiency but also ensures the accuracy and stability of the filter plate 32 during replacement.

[0023] Furthermore, as an improvement to the filter plate 32, the filter plate 32 of this application includes a filter screen portion 3201 for filtering the cooling medium, perpendicular to the inlet pipe 5 and having the same cross-sectional shape as the inlet pipe 5, and a flow-blocking portion 3202 covering the filter screen portion 3201. The cross-sectional dimension of the filter screen portion 3201 is equal to the cross-sectional dimension of the inlet pipe 5, which allows the filter screen portion 3201 to better fit with the inlet pipe 5, thereby achieving filtration of the cooling medium. At the same time, the flow-blocking portion 3202 further prevents the cooling medium from flowing out from the edge of the filter screen portion 3201, improving the filtration effect.

[0024] Furthermore, the direction of the filter screen's extension and retraction is vertical. When replacing the filter screen, especially when the first filter plate 321 is working and the second filter plate 322 protrudes from the front auxiliary filtration mechanism 2, it can also ensure that the second filter plate 322 does not protrude in the horizontal direction relative to the transformer body 1. This can prevent the filter plate 32 from being damaged by surrounding objects during the daily operation of the high-frequency transformer.
