Abstract
The utility model discloses an explosion-proof frequency transformer. A heat pipe radiator is arranged at the back of an explosion-proof box body; through using the features of the heat pipe such as fast heat transfer and small temperature difference between two ends, heat inside an explosion-proof cavity is led out at first, and heat dissipation can be performed on the inner cavity of the box body through an externally-arranged fan and heat dissipation fins. The performance of the heat pipe radiator is 10 times higher than that of a solid radiator, and with the externally-arranged fan combined, external air cooling can be realized, such that cooling efficiency can be higher; and the heat pipe has high heat dissipation efficiency, and the temperature rise of a power module of the frequency transformer is small, and therefore, operational stability and reliability of the explosion-proof frequency transformer can be improved; and further, the heat pipe radiator and the fan are externally arranged, such that the magnitude of the heat pipe and the fan can be adjusted according to the power of the explosion-proof frequency transformer, and therefore, requirements of clients for various kinds of power levels can be satisfied, and the explosion-proof frequency transformer is convenient to maintain.
Description
Technical field
The utility model relates to a kind of explosion-proof frequency converter.
Background technology
Common frequency converter cannot use in deathtrap, because frequency converter can produce a large amount of heat in running, the main pyrotoxin of frequency converter is semiconductor element, the normal operating temperature range of device is generally-5～+ 65 ℃, surpass this scope, element function will significantly decline, can not steady operation, thus affect system reliability of operation.So the design explosion separation structure of explosion-proof frequency converter just seems particularly important.
All electronic devices of explosion-proof frequency converter are encapsulated in the main chamber of explosion-proof casing, air-cooled cannot realization; Water-cooled needs water circulation system and radiator, and the large installation and maintenance of volume is inconvenient, and especially to severe work condition environment condition, this kind of radiating mode also should not be used.
Traditional explosion-proof frequency converter adopts forced draft control cubicle, and operation needs instrument wind, and needs to purge before operation, increases operating cost.Adopt explosion-proof frequency conversion device heat dissipation problem urgently to be resolved hurrily, only depend on box house space heat elimination to can not meet heavy-duty motor work at all, the bad frequency converter temperature rise internal protection that affects that dispels the heat can not move.
Traditional explosion-proof frequency converter shortcoming:
1. operation needs distribution source;
2. before operation, need the purge time about 30 minutes;
3. casing heat-sinking capability is poor, cannot meet the heat radiation requirement of frequency converter.
Summary of the invention
The utility model object is to provide a kind of explosion-proof frequency converter, and the radiating efficiency that it improves explosion-proof frequency converter has improved the job stability of explosion-proof frequency converter, safe and reliable.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of explosion-proof frequency converter, explosion-proof frequency converter comprises flameproof cabinet and case lid two parts, flameproof cabinet is divided into explosion insulation main cavity body and is located at the explosion insulation connecting line cavity body of explosion insulation main cavity body below, explosion insulation main cavity body is comprised of heat-pipe radiator, explosion-proof fan, heat-pipe radiator is coordinated and is arranged on the back of flameproof cabinet and corresponding with explosion insulation main cavity body position by explosion suppresion surface, explosion-proof fan is arranged on the below of heat-pipe radiator, and the air outlet of described explosion-proof fan is connected with heat-pipe radiator.
For technique scheme, inventor also has further optimization embodiment.
As optimization, described explosion-proof frequency converter casing top is provided with protective cover, and for waterproof and the foreign matter of heat-pipe radiator, explosion-proof frequency converter box back surface arranges.
As optimization, the operating grip of described anti-explosion mechanism is located at the side of explosion-proof frequency converter casing.
Further, the case lid of explosion-proof frequency converter is provided with observation window, is installed on controller display screen on observation window, for showing the operational factor of frequency converter.
Than solution of the prior art, the utility model advantage is:
The described a kind of explosion-proof frequency converter of the utility model, it arranges heat-pipe radiator at the back of flameproof cabinet, utilize the heat transfer of heat pipe fast, the characteristics such as two ends have a narrow range of temperature, first by outside the temperature export cavity in flame proof cavity, by blower fan and the radiating fin of peripheral hardware, realize the heat radiation to box house cavity.Because heat-pipe radiator can improve more than 10 times than the performance of entity radiator, in conjunction with the blower fan of peripheral hardware, realize the additional air-cooled cooling performance that makes again higher, heat pipe heat radiation efficiency is high, and the temperature rise of transducer power module is little, and then improves job stability and the reliability of explosion-proof frequency converter.In addition, because heat-pipe radiator and blower fan are all peripheral hardwares, thereby can adjust according to explosion-proof frequency converter power the size of heat pipe and blower fan, thereby can meet client's various power grade requirements, easy to maintenance.
