Abstract

The utility model relates to an open pore pot-shaped magnetic core for a switch transformer, relating to the field of transformers. The open pore pot-shaped magnetic core for the switch transformer comprises a magnetic core body (1), wherein a pot wall (1-2) is arranged on the circumference of the magnetic core body (1); a groove (1-4) and a groove (1-5) are arranged on the periphery of the magnetic core body (1); an open pore (1-1) is arranged in the middle of the magnetic core body (1); the groove (1-4) and the groove (1-5) mutually correspond through the open pore (1-1); the open pore (1-1) is provided with a radiating rod (1-3), and the height and the direction of the radiating rod (1-3) are consistent to those of the pot wall (1-2). According to the utility model, the open pore (1-1) of the magnetic core body (1) is provided with the radiating rod (1-3), and therefore, the heat inside the magnetic core body (1) is emitted out through the radiating rod (1-3). When in use, the open pore pot-shaped magnetic core disclosed by the utility model can be effectively reduced in temperature, thereby ensuring that the switch transformer has excellent heat dissipation characteristic during work, enabling the switch transformer to stably and reliably work and prolonging the service life of the switch transformer.

Description

A kind of perforate jar shape magnetic core that is used for switch transformer

Technical field:

The utility model relates to a kind of switch transformer magnetic core, is specifically related to a kind of perforate jar shape magnetic core that is used for switch transformer.

Background technology:

Switch transformer uses the magnetic core of shapes such as EE, EI and PQ usually; The magnetic core of two kinds of shapes is packed in the skeleton,, process a kind of transformer around the copper coil of last some.But this transformer in actual use; Especially when powerful switch transformer is worked; The magnetic core internal temperature can be very high, and the magnetic core outside also has a certain amount of copper coil, causes the inner heat of magnetic core to come out; In case surpass the Curie temperature of magnetic core, switch transformer will be worked.

The utility model content:

The purpose of the utility model provides a kind of perforate jar shape magnetic core that is used for switch transformer, and it can effectively solve the thermal diffusivity problem of existing switch transformer with magnetic core, increases work efficiency, and prolongs its useful life.

In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises magnetic core body 1, is provided with tank skin 1-2 around the magnetic core body 1, and magnetic core body 1 outer periphery is equipped with two groove 1-4 and groove 1-5; Be provided with a perforate 1-1 in the middle of the magnetic core body 1; Groove 1-4 and groove 1-5 are corresponding with perforate 1-1, and perforate 1-1 place is provided with heat-radiating rod 1-3, and the height of heat-radiating rod 1-3, direction are consistent with tank skin 1-2.

The perforate 1-1 place that the utility model is employed in magnetic core body 1 adds heat-radiating rod 1-3, and magnetic core body 1 inner heat is come out through heat-radiating rod 1-3.
