[0002] A transformer rectifier is a composite power conversion device that steps down and rectifies alternating current (AC) to output the required direct current (DC).

[0003] Transformer rectifiers generate heat during operation. To prevent heat accumulation and excessive temperature that could affect the lifespan of internal electrical components, cooling fans and filters are typically installed inside the transformer rectifier. However, current transformer rectifiers, cooling fans, and filters are generally fixed in design and difficult to disassemble. This affects subsequent cleaning or replacement of the filters, and if the cooling fan is damaged, it is also difficult to repair or replace. Therefore, improvements are needed.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Reference Figures 1-5According to an embodiment of the present invention, an easily detachable transformer rectifier housing includes a base plate 11 and a cover plate 12 mounted on the base plate 11. The transformer rectifier body or transformer rectifier components can be placed on the base plate 11 and installed in the cover plate 12 for protection, so that the easily detachable transformer rectifier housing constitutes a complete transformer rectifier.

[0031] The installation method of the cover plate 12 relative to the base plate 11 is as follows: two baffles 21 are distributed on the left and right sides of the cover plate 12 respectively, and locking plates 22 are distributed on the front and back sides of the cover plate 12 respectively. The locking plates 22 are also provided with a locking component that can be extended and inserted into the slot of the cover plate 12.

[0032] Specifically, such as Figure 2 As shown, the locking assembly includes a spring groove disposed within the locking plate 22. A insert plate 23 is slidably connected to the spring groove. The size of the insert plate 23 is adapted to the slot, and the insert plate 23 is connected to the bottom surface of the spring groove by a spring. When the insert plate 23 is inserted into the slot, the vertical position of the cover plate 12 is limited. The baffle 21 and the locking plate 22 can lock the left and right and front and back positions of the cover plate 12 respectively, thereby completing the locking of all degrees of freedom of the cover plate 12.

[0033] To facilitate the removal of the cover plate 12 by the staff, the left and right sides of the spring groove extend outward to form a sliding groove 24, and the side of the insert plate 23 is integrally formed with a connecting plate 25 extending into the sliding groove 24. A control plate 26 is fixed on the connecting plate 25 and attached to the side of the locking plate 22. The side of the control plate 26 away from the locking plate 22 is processed with friction texture, that is, the staff can use the control plate 26 to push the connecting plate 25 and the insert plate 23 outward, so that the insert plate 23 is disengaged from the slot. At this time, the cover plate 12 can be lifted and disengaged from the base plate 11, so that the staff can inspect and repair the transformer rectifier body or transformer rectifier components on the base plate 11.

[0034] In addition, in order to improve the heat dissipation capacity of the easily detachable transformer rectifier housing and avoid excessive temperature inside the cover plate 12 that would reduce the lifespan of electrical components, an air inlet and an air outlet 13 are respectively provided on the left and right sides of the cover plate 12. A filter assembly and an air intake assembly facing the air inlet and the air outlet 13 are respectively installed on the left and right sides of the cover plate 12.

[0035] To facilitate disassembly and assembly, a positioning frame 31 is installed on the left and right sides of the cover plate 12. The positioning frame 31 includes a horizontal plate and vertical plates fixed to the lower side of the horizontal plate and distributed front and back. The filter assembly and the suction assembly are respectively installed in the left and right positioning frames 31.

[0036] like Figure 5 As shown, the filter assembly includes a first mounting box 41, which contains a filter 42. The front and rear sides of the first mounting box 41 are integrally formed with a first limiting plate 43. The first mounting box 41 is clamped between the front and rear vertical plates and is pressed onto the baffle 21 by the horizontal plate. The first limiting plate 43 is pressed onto the cover plate 12 by the vertical plate.

[0037] Similarly, the suction assembly includes a second mounting box 51, which houses a fan assembly. The front and rear sides of the second mounting box 51 are integrally formed with a second limiting plate 52. The second mounting box 51 is clamped between the front and rear vertical plates and pressed against the baffle 21 by the horizontal plate. The second limiting plate 52 is pressed against the cover plate 12 by the vertical plates.

[0038] With the above installation method, when the cover plate 12 is not installed on the base plate 11, the first mounting box 41 and the second mounting box 51 can slide up and down in the positioning frame 31 and can be completely separated from the cover plate 12 and the positioning frame 31, so as to facilitate disassembly, maintenance and replacement.

[0039] When the cover plate 12 is fixed to the base plate 11, the baffle 21 will cooperate with the positioning frame 31 to completely lock the suction assembly and the filter assembly.

[0040] In addition, in order to further improve the strength of the vertical rod and prevent it from easily deforming, the upper side of the baffle 21 is provided with a slot for accommodating the vertical plate.

[0041] Furthermore, to facilitate the positioning and installation of the cover plate 12, the upper side of the insert plate 23 is chamfered with the side closest to the cover plate 12, and the upper side of the baffle 21 is also chamfered with the side closest to the cover plate 12. With the above design, the operator does not need to push the control plate 26 backward, but only needs to press down the cover plate 12 to complete the locking of the cover plate 12 relative to the base plate 11. During this process, the insert plate 23 can automatically retract under pressure and spring into the slot.

[0042] It should be noted that the heat dissipation fins on the upper end of the cover plate 12 and the fasteners for easy installation and locking in the base plate 11 are conventional settings in the prior art and will not be described in detail here.

[0043] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
