Abstract
The utility model discloses a kind of chopper that reduces and the structure of bottom surface temperature rise is installed, it includes installing bottom surface and cover plate, it is arranged at intervals with several heater members on described installation bottom surface, wherein, on described installation bottom surface, the periphery in described heater members is provided with some convex tendons, and described cover plate is installed on described installation bottom surface and by having heat emission space between convex tendon and described installation bottom surface.Above-mentioned reduction chopper is installed the structure of bottom surface temperature rise and is had additional some convex tendons on chopper installation bottom surface, outside described cover plate is arranged at convex tendon and with convex tendon, there is heat emission space, thus strengthen chopper and the cross-ventilation of bottom surface is installed, dispelled the heat by cross-ventilation.It is not only simple in structure, it is easy to accomplish；And significantly reduce chopper and the temperature rise of bottom surface is installed.
Description
Technical field
This utility model relates to a kind of chopper, especially relates to a kind of chopper that reduces and installs bottom surface temperature rise
Structure.
Background technology
Chopper refers to close, carry and cut-off the electric current under normal loop condition and can close, on rule
The switching device of the electric current carried in the fixed time and cut-off under abnormal loop condition.Chopper uses model by it
Enclosing and be divided into primary cut-out and low-voltage circuit breaker, high-low pressure identification of boundaries is fuzzyyer, typically by more than 3kV
Be referred to as High-Voltage Electrical Appliances.
Chopper can be used to distribute electric energy, infrequently starts asynchronous motor, to power circuit and motor
Deng carrying out protection, when there are serious overloads or the fault such as short-circuit and under-voltage in them can automatic shutdown circuit,
Its function is equivalent to Fuse switch and crosses the combination of underheat relay etc..And after disjunction fault current
Typically need not change parts.At present, obtain a wide range of applications.
The temperature rise installing bottom surface of chopper, as its current-carrying electric conductor, all should comply with wanting of relevant criterion
Ask.But, along with chopper volume is towards the development of trend toward miniaturization, meet the temperature increase requirement installing bottom surface
Become a difficult problem.
Utility model content
The purpose of this utility model is to provide a kind of chopper that reduces to install the structure of bottom surface temperature rise, and it has
Simple in construction and effectively reduce chopper and install the feature of bottom surface temperature rise, deposits solving chopper in prior art
The problems referred to above.
For reaching this purpose, this utility model by the following technical solutions:
A kind of chopper that reduces installs the structure of bottom surface temperature rise, and it includes installing bottom surface and cover plate, described installation
Several heater members it are arranged at intervals with, wherein, in described heater members on described installation bottom surface on bottom surface
Periphery is provided with some convex tendons, and described cover plate is installed on described installation bottom surface and by convex tendon and described peace
Dress has heat emission space between bottom surface.
Especially, described installation bottom surface being arranged at intervals with three heater members side by side, described convex tendon is provided with
Article four, including a upper convex tendon, a lower convex tendon and two side convex tendons, two of which side convex tendon is symmetrical arranged
In the outside of two heater members of outermost, described upper convex tendon and lower convex tendon are symmetricly set in of centre
The upper and lower of thermal device.
Especially, the inwall of described cover plate is close on the bottom surface of described convex tendon.
Especially, described upper convex tendon is identical with the length of lower convex tendon, and described upper convex tendon and the length of lower convex tendon
More than the length of described side convex tendon, and described upper convex tendon, lower convex tendon are identical with the height of side convex tendon.
The beneficial effects of the utility model are, the most described reduction chopper installs bottom surface temperature rise
Structure install on bottom surface in chopper and have additional some convex tendons, outside described cover plate is arranged at convex tendon and with
Convex tendon has heat emission space, thus strengthens chopper and install the cross-ventilation of bottom surface, is entered by cross-ventilation
Row heat radiation.It is not only simple in structure, it is easy to accomplish；And significantly reduce chopper and the temperature rise of bottom surface is installed.

Profile.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Referring to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of chopper that reduces installs the knot of bottom surface temperature rise
Structure includes installing bottom surface 1 and cover plate 2, and described installation bottom surface 1 is arranged at intervals with three heater members 3 side by side,
On described installation bottom surface 1, the periphery in described heater members 3 is provided with four convex tendons, and these four convex tendons include
Article one, the upper lower convex tendon 5 of convex tendon 4, and two side convex tendons 6, two of which side convex tendon 6 is symmetricly set in
The outside of two heater members 3 in outside, described upper convex tendon 4 and lower convex tendon 5 are symmetricly set in of centre
The upper and lower of heater members, described upper convex tendon 4 is identical with the length of lower convex tendon 5, and described upper convex tendon 4
Length with lower convex tendon 5 is more than the length of described side convex tendon 6, and described upper convex tendon 4, lower convex tendon 5 and side are convex
The height of muscle 6 is identical.
Described cover plate 2 is installed on described installation bottom surface 1 and by having between convex tendon and described installation bottom surface 1
Having heat emission space, the spacing between the most described installation bottom surface 1 and described cover plate 2 is H, thus strengthens open circuit
The cross-ventilation of bottom surface installed by device, is dispelled the heat by cross-ventilation.
The inwall of described cover plate 2 is close on the bottom surface of described convex tendon, to be divided into some by installation bottom surface 1
Individual heat dissipation channel, two that three heater members of both sides formation 3 of a heater members in centre share dissipate
The passage of heat, it is simple to air circulates.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by upper
Stating example to limit, on the premise of without departing from this utility model spirit and scope, this utility model is the most various
Change and change, in the range of these changes and change both fall within claimed this utility model.This practicality is new
Type claims scope and is defined by appending claims and equivalent thereof.
