Abstract

The utility model discloses a reactor of cooling area increase, including iron core and the coil of coiling on the iron core, arbitrary coil includes a plurality of coil units that parallel, has the clearance between every two adjacent coil units. Compared with the prior art, the heat dissipation area of the coil is increased, and the reactor dissipates heat by utilizing the structure of the reactor, so that the reduction of the cooling energy consumption of the reactor is facilitated.

Description

Reactor with increased cooling area

Technical Field

The utility model relates to a reactor, concretely relates to reactor of cooling structure.

Background

In a reactor, when a current flows through a coil wire, heat is generated, and therefore, the reactor needs to be cooled or radiated. If the reactor is matched with a cooling system, the cost is high and the energy consumption is high.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the reactor dissipates heat by its own structure.

In order to solve the technical problem, the utility model provides a following technical scheme: the reactor with the increased cooling area comprises an iron core and coils wound on the iron core, wherein any coil comprises a plurality of parallel coil units, and a gap is formed between every two adjacent coil units.

Compare in prior art, the heat radiating area of arbitrary coil, except the surface of traditional coil, increased the clearance between two adjacent coil units, so, the heat radiating area of coil has increased. The heat generated in any one of the coil units can be dissipated through the gap and the outer surface of the coil unit, that is, the reactor dissipates heat by its own structure, which is advantageous for reducing the cooling power consumption of the reactor.

Detailed Description

Referring to fig. 1, a reactor with an increased cooling area includes a core and coils wound around the core, where any coil includes a plurality of parallel coil units 10, and a gap 11 is provided between every two adjacent coil units.

The gap 11 is matched with a parting strip 20, and in the winding process of the coil, the parting strip can effectively separate two adjacent coil units 10, so that the gap 11 can be maintained.

As shown in fig. 5, the number of coils is two, and the coils are wound on two core portions of the iron core respectively. The whole iron core is rectangular, the middle part is a core part, and the two ends are iron yokes 30.

As shown in fig. 5, a bracket 40 is mounted on any one of the yokes 30, and a first connecting portion 41 extending outward is provided at the bottom of the bracket, and a second connecting portion 42 extending inward is provided at the top of the bracket. Specifically, a pair of bilaterally symmetric brackets 40 are mounted on the yoke at each end of the core. The first connection portions 41 of the pair of brackets are formed in a splayed shape, and can stably support the reactor. Both the first connection portion 41 and the second connection portion 42 can be used for mounting the reactor.

As a modification, as shown in fig. 5, any one of the brackets 40 is mounted on the yoke 30 by a plurality of first threaded connectors 43, one of which is connected to an insulator 44 connected to a second threaded connector 45, and the second threaded connector is connected to a side plate 46, on which cables connected to the coils can be mounted, and a right-angled attachment 47 can be mounted. The first threaded connecting piece connected with the insulator is a middle threaded connecting piece, and the first threaded connecting pieces positioned on two sides of the middle threaded connecting piece are side threaded connecting pieces. The insulator 44 prevents the magnetic flux in the core from leaking out through the middle threaded connection and the second threaded connection 45. The additional piece 47 is located at the periphery of the side threaded connection piece, so that unnecessary electromagnetic loops formed by the side threaded connection piece and other parts of the reactor can be avoided, and the two ends of the coil can be effectively limited.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
