Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a dry-type transformer with enhanced heat dissipation. Background Technique

[0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Simply put, a dry-type transformer refers to a transformer in which the iron core and windings are not impregnated in insulating oil.

[0003] In the prior art, in order to enhance the heat dissipation intensity of dry-type transformers, heat dissipation fans are usually additionally installed at the bottom of dry-type transformers to dissipate the heat generated during their operation. Over time, impurities such as dust and fibers in the air will gradually accumulate on the blades, the housing and the surrounding ventilation openings of the heat dissipation fans. These accumulated dusts will block the ventilation channels of the fans and reduce the cross-sectional area of air flow. Therefore, it is necessary to process them regularly.

[0004] However, since the heat dissipation fan is fixed at a specific position at the bottom of the dry-type transformer, the space around it is often relatively narrow and is closely connected to the structure of the transformer body. When it is necessary to clean the heat dissipation fan, it is difficult for the operator to obtain sufficient operating space, which increases the difficulty of the cleaning work, and also reduces the cleaning effect and efficiency. Moreover, when cleaning the fixedly installed heat dissipation fan, it is often necessary to first disassemble some components connected to the transformer body or perform partial displacement operations on the transformer. This not only requires a large amount of time and manpower, but also may cause certain interference to the normal operation of the transformer.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a dry-type transformer with enhanced heat dissipation to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, a dry-type transformer with enhanced heat dissipation provided by the utility model includes a transformer body. A heat dissipation seat with a hollow structure is fixedly installed at the bottom of the transformer body. An installation seat is inserted into the interior of the heat dissipation seat. A heat dissipation opening is formed in the bottom wall of the installation seat. A heat dissipation fan that blows air upward is installed inside the heat dissipation opening. The heat dissipation seat and the installation seat are fixed by a locking member.

[0008] Furthermore, a support seat is fixedly installed at the bottom of the transformer body. The heat dissipation seat is arranged at the bottom of the support seat. A support base is connected to the bottom of the heat dissipation seat.

[0009] Furthermore, a connecting piece is arranged on the side wall of the support, and a plurality of connecting pieces are provided. The plurality of connecting pieces are arranged at equal intervals along the side wall of the support in the length direction, and the support and the support base are fixed through the plurality of connecting pieces.

[0010] Furthermore, the locking member includes a locking ear connected to the side of the mounting base and a locking buckle connected to the side of the heat dissipation base. The locking buckle and the locking ear are vertically symmetrical, and the locking ear is buckled on the locking buckle.

[0011] Furthermore, an upper dust-proof net is fixedly installed on the top of the heat dissipation base, and a lower dust-proof net corresponding to the upper dust-proof net is installed on the bottom wall of the heat dissipation base.

[0012] Furthermore, a first opening is formed on the top wall of the heat dissipation base, the upper dust-proof net is installed inside the first opening, a second opening corresponding to the first opening is formed on the bottom wall of the heat dissipation base, the lower dust-proof net is installed inside the second opening, and a receiving space is integrally formed inside the heat dissipation base, and the mounting base is inserted into the inside of the receiving space.

[0013] Furthermore, the upper dust-proof net includes a plurality of strip-shaped filters arranged along the length direction of the first opening. The plurality of strip-shaped filters are arranged at intervals, and heat dissipation fins are installed in the intervals between two adjacent strip-shaped filters. The heat dissipation fins are perpendicular to the strip-shaped filters and extend into the inside of the receiving space.

[0014] Furthermore, a plurality of cleaning blocks are arranged on one side of the mounting base, a cleaning slot for the heat dissipation fins to pass through is formed between two adjacent cleaning blocks, and cleaning bristles are arranged on the inner side wall of the cleaning slot.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, by releasing the locking member and pulling out the mounting base from the inside of the heat dissipation base, the staff can manually disassemble the mounting base. On the one hand, it is convenient to carry during the installation and handling of the transformer body. On the other hand, it is convenient for the later staff to repair and clean the heat dissipation base and the mounting base, and the applicability is high.

[0017] 2. In the present utility model, the sliding of the mounting base inside the receiving space can drive the cleaning block to move along the outer surface of the heat dissipation fin. The outer surface of the heat dissipation fin can be cleaned through the cleaning slot formed between two adjacent cleaning blocks. By cleaning the surface of the heat dissipation fin and removing these impurities, the clean state of the surface of the heat dissipation fin can be restored, so that heat can smoothly transfer from the heat source to the heat dissipation fin and then be dissipated into the surrounding environment through the heat exchange between the heat dissipation fin and the air.
