Description
(1) technical field
The utility model relates to a kind of air themperature cooling device.Be to be used for explosion-proof cooler that explosion-proof tank is cooled specifically, be applicable to that the explosion-proof tank to various heaters (heater element) such as frequency converter, soft initiator, power model, thyristor, capacitor and resistor are installed cools.
(2) background technology
As everybody knows, all be provided with the explosion-proof tank that is used for installing heaters (heater element) such as frequency converter, soft initiator, power model, thyristor, capacitor and resistor on some electric equipments of dangerous situation such as inflammable, explosive, this explosion-proof tank is a hermetic type.Because explosion-proof tank is hermetic type, is hedged off from the outer world, the heater (heater element) in it its temperature in the course of the work can raise, thereby the air themperature in the Flameproof box is raise.When the air themperature in the Flameproof box surpassed the working temperature of heater (heater element), not only heater (heater element) easily shortened in aged deterioration, useful life, and electric equipment can't normally move.Therefore, must reduce the interior air themperature of explosion-proof tank.
At present, the air themperature that reduces in the explosion-proof tank mainly contains following two kinds of methods: the one, on the box outer surface of Flameproof box, fin is set, increase the area of dissipation of casing, heat radiation is dried, forced to casing, reduce the air themperature in the casing by blower fan.This method can only solve the heat dissipation problem of casing, the atmosphere temperature rising speed in the reduction casing, can not realize the air in the casing is directly lowered the temperature; The 2nd, on the tank wall of Flameproof box, heat pipe is installed, and is made the heater (heater element) in the casing be close to that tank wall that heat pipe is installed, utilize the medium in the heat pipe that the heat on the casing is distributed.
Above dual mode all is to adopt radiating principle to reduce the temperature of casing.Though can reduce atmosphere temperature rising speed in the casing by the radiating treatment to casing, the time one is long, and the temperature in the casing still can raise gradually.When the air themperature in the casing was elevated to working temperature above heater (heater element), electric equipment still can't normally move.
(3) utility model content
Problem to be solved in the utility model provides a kind of explosion-proof cooler.Adopt this explosion-proof cooler, can realize the thermostatic control of air themperature in the explosion-proof tank, the heater of electric equipment (heater element) is difficult for aged deterioration, long service life, guarantees the normal operation of electric equipment.
For addressing the above problem, the utility model is taked following scheme:
The characteristics of explosion-proof cooler of the present utility model are to contain casing, evaporator, compressor and condenser, and evaporator is in the casing, and compressor and condenser are in outside the casing.Air inlet, air outlet and interface installing hole are arranged on the casing, blower fan is arranged in the air outlet, in the interface installing hole explosion suppression interface is arranged.The import of evaporator is connected with the outlet of condenser by an expenditure and pressure element, explosion suppression interface and pipeline, its outlet links to each other with the import of compressor by another explosion suppression interface and pipeline, and the outlet of compressor is then joined by the import of pipeline and condenser.
Take such scheme, have the following advantages:
Because explosion-proof cooler of the present utility model contains casing, evaporator, compressor and condenser, evaporator is in the casing, and compressor and condenser are in outside the casing.Air inlet, air outlet and interface installing hole are arranged on the casing, in the interface installing hole explosion suppression interface is arranged.The import of evaporator is connected with the outlet of condenser by an expenditure and pressure element, explosion suppression interface and pipeline, its outlet links to each other with the import of compressor by another explosion suppression interface and pipeline, and the outlet of compressor is then joined by the import of pipeline and condenser.During work, the air that enters casing from air inlet can become cold air and discharge from air outlet after evaporator cools.When being used for explosion-proof tank lowered the temperature, as long as on explosion-proof tank, also process into and out of the air port, should into and out of the air port respectively with the utility model casing on into and out of the air port corresponding and the connection, under the effect of blower fan, hot-air in the explosion-proof tank will enter from the air inlet of its air outlet and the utility model casing in the casing of the present utility model, send in the explosion-proof tank again through after the evaporator cools, thereby make the air in the explosion-proof tank keep constant temperature.
Because the temperature in the explosion-proof tank can keep constant temperature, the heaters (heater element) such as frequency converter, soft initiator, power model, thyristor, capacitor and resistor in it can be in the constant temperature operational environment all the time.So, not only heater (heater element) is difficult for aged deterioration, uses the longevity to prolong, and can also guarantee the normal operation of electric equipment.
