Description
Technical field
It the utility model is related to field of circuit breakers, more particularly to a kind of breaker of good heat dissipation effect.
Background technology
Breaker is to refer to close, carry and cut-off the electric current under normal loop condition, and can be closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition (including short circuit condition).Breaker can be used to distribute electricity
Can, infrequently start asynchronous motor, the implementations such as power circuit and motor protected, when they occur serious overloads or
During the failures such as person is short-circuit and under-voltage can automatic shutdown circuit, its function is equivalent to Fuse switch with crossing underheat relay etc.
Combination.And it is latter in disjunction fault current as need not change parts.Breaker typically by contact system, arc quenching system,
Operating mechanism, electrical apparatus release, shell etc. are formed.In use, when running into line short, circuit breaker internal can produce breaker
Raw substantial amounts of heat, because each breaker monomer is fixed side by side, the contact surface of adjacent breaker monomer is plane, therefore disconnected
Amount of heat inside the device monomer of road can not distribute from both sides in time, potential safety hazard be present, meanwhile, it can also shorten making for breaker
Use the life-span.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of breaker of good heat dissipation effect, there is good thermal diffusivity
Can, so as to solve the problems, such as to be pointed out in background technology.
The technical solution adopted in the utility model is：
A kind of breaker of good heat dissipation effect, including at least two breaker monomers fixed side by side, the breaker list
Two middle side parts of body vertically offer a radiating groove above and below breaker monomer, the open top of the radiating groove
In up big and down small horn-like, be fixed with multiple radiating fins at the top of the radiating groove, between adjacent radiating fin between
Away from gradually increase, the side bottom of radiating fin two from lower to upper heat-conducting glue, the radiating groove are scribbled with radiating groove connecting position
Bottom opening in up-small and down-big horn-like, the central region of the radiating groove is fixed with multiple vertical wind guide strips, described
Wind guide strip and radiating groove side wall it is contour.
Preferably, the height of the radiating fin is less than the height of radiating groove sidewall, described wind guide strip equidistantly divides
Cloth, open top and the bottom opening of the radiating groove are symmetrical arranged.
The beneficial effects of the utility model：Quick heat radiating is carried out to heat caused by breaker monomer, so as to eliminate safety
Hidden danger, extend the service life of breaker, when multiple breaker monomers are fixed together side by side, due to radiating fin thermal conductivity
Can preferably, the transmission that heat caused by inside breaker monomer first passes around breaker monomer is absorbed by radiating fin, radiating fin
Piece is realized heat exchange with outside air and cooled, so as to realize the Quick diffusing to breaker monomer internal heat, radiating groove
The contact area of breaker monomer shell and air is increased, so as to realize that breaker monomer shell and air directly produce heat
Exchange and realize radiating, due to quick absorption of the radiating fin to heat, heat is largely focused on radiating fin upwards, hot gas
Move upwards, thus the heat at the top of radiating groove upwards motion with air carry out heat exchange, without with radiating groove
The air of side carries out heat exchange.
Brief description of the drawings
Fig. 1 is the structural representation that two breaker monomers are fixed together side by side；
Fig. 2 is the side structure schematic diagram of breaker monomer；
In figure：1. breaker monomer, 2. radiating grooves, 3. radiating fins, 4. wind guide strips.
Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Embodiment 1
As shown in Figure 1-2, a kind of breaker of good heat dissipation effect, including at least two breaker monomers 1 fixed side by side,
Two middle side parts of the breaker monomer 1 vertically offer one and run through radiating groove 2 of the breaker monomer about 1, described
In up big and down small horn-like, the top of the radiating groove 2 is fixed with multiple radiating fins 3, adjacent for the open top of radiating groove 2
Radiating fin 3 between spacing gradually increase from lower to upper, described 3 liang of side bottoms of radiating fin and the connecting position of radiating groove 2
Heat-conducting glue is scribbled, the heat on breaker monomer 1 can be rapidly transferred on radiating fin 3 by heat-conducting glue, the radiating groove 2
For bottom opening in up-small and down-big horn-like, the central region of the radiating groove 2 is fixed with multiple vertical wind guide strips 4, described
Wind guide strip 4 and radiating groove 2 side wall it is contour, wind guide strip 4, which not only has, leads wind action, and in adjacent breaker monomer
1 it is arranged side by side when, there is certain supporting role, by increasing capacitance it is possible to increase the intensity of breaker monomer 1.
The height of the radiating fin 3 is less than the height of the side wall of radiating groove 2, and adjacent breaker monomer 1 is in juxtaposition
When, the radiating fin 3 on circuit breakers monomer 1 is separated from each other, and which increases contact of the radiating fin 3 with outside air
Area, the heat exchange of radiating fin 3 and outside air, the described equidistantly distributed of wind guide strip 4, the radiating groove can be accelerated
2 open top is symmetrical arranged with bottom opening.
