Description

Technical Field

[0001] This utility model relates to the field of box-type transformer technology, and more specifically, to a box-type energy-saving transformer. Background Technology

[0002] The box-type energy-saving transformer integrates the traditional transformer into a box-type shell, featuring small size, light weight, low noise, low loss, and high reliability. As a complete set of power distribution equipment, it is organically combined with transformer, high-voltage control equipment, and low-voltage control equipment, and is widely used in residential communities, commercial centers, stations, airports, factories, mines, enterprises, hospitals, schools and other places. Currently, existing transformers dissipate heat through side-mounted fins, but heat accumulation cavities are formed between adjacent fins, resulting in slow heat dissipation and failing to achieve rapid heat dissipation. To address the aforementioned issues, this application proposes a box-type energy-saving transformer. Utility Model Content

[0003] The purpose of this invention is to provide a box-type energy-saving transformer that solves the problem of slow heat dissipation of heat sink fins in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A box-type energy-saving transformer includes a box housing and a transformer and heat dissipation unit inside it; The transformer has fins on its side; The heat dissipation unit includes a heat dissipation box and heat dissipation pipes connected to each other; The heat dissipation box is fixed to the top of the inner wall of the box body. The heat dissipation pipe includes a main pipe and a bypass pipe, and the side of the bypass pipe is provided with a heat absorption pipe, located between adjacent fins.

[0005] Preferably, the main pipe includes two closed-loop pipes, an inner and an outer one, which are a flow supply pipe and a return pipe, respectively.

[0006] Preferably, one end of the supply pipe and the return pipe are respectively connected to the inlet and outlet of the bypass pipe, and the heat absorption pipe is fixedly installed on one side of the bypass pipe body, forming a coil.

[0007] Preferably, the main tube comprises two parallel vertical tubes, both of which are connected to a heat sink at their upper ends.

[0008] Preferably, the lower end of the main pipe is connected to both ends of the bypass pipe, and the heat absorption pipe is fixedly installed on one side of the bypass pipe body and is a horizontal pipe.

[0009] Preferably, the horizontal pipes are arranged side by side in a horizontal direction, and branch pipes are fixedly connected between adjacent horizontal pipes.

[0010] Preferably, the branch pipe has a through hole inside.

[0011] The beneficial effects of this utility model are: 1. By interlacing the heat absorption tubes and fins, the flow of the medium inside the tubes carries away the heat between adjacent fins, thereby accelerating heat dissipation and preventing some heat from accumulating between adjacent fins and affecting subsequent heat dissipation efficiency. 2. By creating evenly distributed holes in the heat absorption tube, dust between adjacent fins can be carried away along with the heat, thus preventing the problem of reduced heat dissipation performance caused by dust adhering to the fins and effectively ensuring the heat dissipation rate of the transformer during long-term operation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] A box-type energy-saving transformer is designed to improve heat dissipation efficiency. By arranging heat dissipation pipes and fins 21 alternately on the inner wall of the box 1, the flow of cooling water in the heat dissipation pipes can remove the heat between adjacent fins 21, or the heat dissipation pipes can apply suction to draw heat and dust outward, thereby accelerating heat dissipation and ensuring the long-term operational stability of the transformer 2. In some embodiments, the specific structure of the box-type energy-saving transformer is as follows: Figure 1-5 As shown, it includes the housing 1 and the transformer 2 and heat dissipation unit 3 inside it; Transformer 2 is an energy-saving box-type transformer, a mature commercial product on the market, and has heat dissipation fins 21 fixedly installed on its side. The heat dissipation unit 3 includes a heat dissipation box 31 and a heat pipe 32; The heat sink 31 is installed on the side wall of the housing 1, located in the top area; The heat pipe 32 includes a main pipe 321 and a bypass pipe 322; Furthermore, the main pipe 321 includes two concentric rings: an outer ring is a flow pipe used to transport the internal medium, and an inner ring is a return pipe used for the return of the internal medium. Furthermore, the end of the main pipe 321 is connected to the heat sink 31, and a bypass pipe 322 is fixedly installed between adjacent main pipes 321, which is fixed to the upper and lower and side areas of the transformer 2. Furthermore, a coil 322a is fixedly installed on one side of the detour tube 322, extending into the cavity between adjacent fins 21; It should be noted that the heat sink 31 is a cold water circulation tank, which is a mature commercial product on the market and will not be described in detail here. It is only used to drive the cooling water to cool down and flow inside the heat sink 32. It is understandable that when cooling water flows through coil 322a, coil 322a is located between adjacent fins 21, which can form heat exchange, thereby carrying away the heat between adjacent fins 21 and achieving the effect of accelerating heat dissipation. Optionally, in order to reduce equipment investment costs, a horizontal pipe 322b is fixedly installed on one side of the detour pipe 322, extending between adjacent fins 21 and located in the upper and lower end areas, and a branch pipe 322b1 is fixedly installed between the upper and lower adjacent horizontal pipes 322b. Furthermore, the main pipe 321 includes two vertical pipe structures, which are respectively connected to the inlet end and the outlet end of the bypass pipe 322, and the upper end of the main pipe 321 is connected to the heat sink 31; In addition, the branch pipe 322b1 has through holes 322b2 that run through both the inside and outside, which are evenly distributed on the pipe body; It should be noted that the heat sink 31 is a suction air pump, which is a mature commercial product on the market and will not be described in detail here. It is only used to transmit the suction force to the inside of the heat sink 32 and is fixedly installed on the top area of ​​the four side walls of the housing 1. It is understandable that by opening the through hole 322b2, the suction force is transmitted to the adjacent fins 21, which can both draw out hot gas to accelerate heat dissipation and draw out dust and impurities into the heat dissipation pipe 32 and finally discharge them outward, thus achieving the effect of cleaning the fins 21 and ensuring stable heat dissipation under long-term operation. Some publicly available information describes the specific usage methods of box-type energy-saving transformers as follows: S1, Example 1: The heat sink 31 delivers cooling water to the inside of the main pipe 321, and then into the inside of the bypass pipe 322. At this time, the side-mounted coil 322a is used to transfer the cooling water between adjacent fins 21, thereby using the cooling water to form a heat exchange with the hot air, achieving the effect of removing heat and improving the heat dissipation efficiency. Then the cooling water enters the return pipe from below, and finally flows into the heat sink 31 for cooling before being output again. S2, Example 2: The heat dissipation box 31 applies a suction force to the heat dissipation pipe 32, and applies the suction force to the horizontal pipe 322b and the branch pipe 322b1 through the two vertical pipes. Then, the suction force is applied between the adjacent fins 21 through the through hole 322b2, thereby removing the hot air and dust impurities between the adjacent fins 21, achieving the dual effect of heat dissipation and cleaning.
