Abstract
The invention relates to a magnetic core heat dissipation structure of a reactor. The magnetic core heat dissipation structure of the reactor comprises an iron core, wherein the iron core is formed through arraying a plurality of alloy magnetic powder cores in a square shape; each of the top and the bottom of the iron core is formed through horizontally arraying four alloy magnetic powder cores in a shape shaped like a Chinese character Tian; each of the left part and the right part of the iron core is formed through vertically arraying four alloy magnetic powder cores in a shape shaped like the Chinese character Tian; air gaps are formed among the left and right vertical alloy magnetic powder cores of the square-shaped iron core and the alloy magnetic powder cores at the bottom, and the air gaps are internally provided with air gap plates. According to the magnetic core heat dissipation structure of the reactor, the air gaps are formed under the left and right vertical alloy magnetic powder cores of the square-shaped iron core, and heat generated by the magnetic cores at the upper parts of the air gaps are more rapidly transmitted to the upper parts and then is dissipated; heat generated at the lower parts of the air gaps is more rapidly transmitted to the lower parts and then is dissipated; compared with a scheme that an air gap is formed in the upper part, the temperature rising of the iron core is remarkably reduced.
Description
Technical field
The present invention relates to reactor field, particularly relate to the heat dissipating structure of magnetic core of reactor.
Background technology
For reactor, the loss of magnetic core be can not ignore.At magnetic core air gap, magnetic resistance can produce
The highest temperature.How to process the temperature at air gap, be that reactor design must take into.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the heat dissipating structure of magnetic core of a kind of reactor, can be faster
Preferably the heat of magnetic core air gap is distributed.
The technical solution adopted for the present invention to solve the technical problems is: the heat dissipating structure of magnetic core of a kind of reactor,
It includes iron core；Described iron core is that hollow arrangement forms by multiple alloy magnetic powder cores；The top of described iron core
It is that matrix pattern is horizontally arranged by four alloy magnetic powder cores respectively with bottom to form；The left part of described iron core and right part
It is that matrix pattern is vertically arranged and forms by four alloy magnetic powder cores respectively；Two, the left and right unshakable in one's determination of described hollow
It is provided with air gap between vertical alloy magnetic powder core and the alloy magnetic powder core of bottom；It is placed with gas in described air gap
Gap plate.
Beneficial effects of the present invention: the heat dissipating structure of magnetic core of the reactor of the present invention, on the left side that hollow is unshakable in one's determination
Arranging air gap under right two vertical alloy magnetic powder cores, the heat that the magnetic core on air gap top produces more quickly passes
Distributing after being delivered to top, the heat that the magnetic core of air gap bottom produces distributes after being more quickly delivered to bottom
Go out；Obvious reduction effect is had than the temperature rise unshakable in one's determination of the scheme using air gap to be placed on top.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the heat dissipating structure of magnetic core of the reactor of embodiment.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is done the most in detail
Thin description, this embodiment is only used for explaining the present invention, constitutes protection scope of the present invention and limit.
Embodiment
As it is shown in figure 1, the heat dissipating structure of magnetic core of a kind of reactor, it includes unshakable in one's determination 1；Described unshakable in one's determination 1 by many
Individual alloy magnetic powder core 2 arranges in hollow and forms；The described top of unshakable in one's determination 1 and bottom are respectively by four alloys
Powder core 2 is horizontally arranged in matrix pattern to be formed；The described left part of unshakable in one's determination 1 and right part are respectively by four alloy magnetic
Powder core 2 is vertically arranged in matrix pattern and forms；The alloy magnetic that two, the left and right of the iron core 1 of described hollow is vertical
It is provided with air gap 3 between the alloy magnetic powder core 2 of powder core 2 and bottom；It is placed with air gap plate 4 in described air gap 3.
The heat dissipating structure of magnetic core of the reactor of the present embodiment, at the vertical alloy in two, left and right that hollow is unshakable in one's determination
Arranging air gap under powder core, the heat that the magnetic core on air gap top produces gives out after being more quickly delivered to top
Going, the heat that the magnetic core of air gap bottom produces distributes after being more quickly delivered to bottom；Than using air gap
The temperature rise unshakable in one's determination of the scheme being placed on top has obvious reduction effect.
Above-described embodiment should not in any way limit the present invention, all employing equivalents or the side of equivalency transform
The technical scheme that formula obtains all falls within protection scope of the present invention.
