Abstract
The utility model discloses a fixed point heat exchange device, including thermostated container, heater, heat exchanger, forced draught blower and guide duct, the forced draught blower is connected with heat exchanger, and heat exchanger links to each other with the heater, guide duct one end and heater link to each other, in the thermostated container is stretched into to the other end, and stretch out thermostated container and heat exchanger intercommunication after the inner wall of thermostated container encircles, it has the air outlet to open on the guide duct. The utility model discloses a forced draught blower replenishes new air for the heater, and via heater heating back, the hot -air gets into to the thermostated container in along with the guide duct, the constancy of temperature of keep a constant temperature incasement, and still there is remaining heat in the hot -air of guide duct after flowing into the thermostated container in addition, and last remaining heat flows into the fresh air who sends into to the heat exchanger in with the forced draught blower and carries out the heat transfer, and in the fresh air entering heater after the heat transfer, the mode through the heat exchange has reduced thermal loss.
Description
Technical field
The utility model relates to a kind of thermostat, is a kind of fixed point heat-exchange device specifically.
Background technology
Common thermostat makes temperature constant by heater heating, but while carrying out heating, more heat can be wasted when being first heat conducting, secondly be that the tail gas after heating may also also exist more heat, after being discharged easily, also can waste more heat.
Utility model content
Utility model object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of fixed point heat-exchange device, comprises insulating box, heater, heat exchanger, pressure fan and guide duct.
Wherein, described pressure fan is connected with heat exchanger, and heat exchanger is connected with heater, and described guide duct one end is connected with heater, and the other end puts in insulating box, and after the inner wall surrounding of insulating box, stretches out insulating box be communicated with heat exchanger; Described guide duct has air outlet.
Wherein, be also provided with temperature measuring equipment in described insulating box, the tail end of guide duct is also provided with magnetic valve; Described temperature measuring equipment is also connected with control device, the controlled device gauge tap of described magnetic valve.
Wherein, the external diameter of pipeline that described pressure fan is connected with heater with heat exchanger and heat exchanger is 2 times of guide duct external diameter.
Wherein, also magnetic valve is provided with between described pressure fan and heat exchanger.
Beneficial effect: the utility model has the following advantages:
(1) the utility model supplements new air by pressure fan to heater, after heater heating, hot-air enters in insulating box with guide duct, keep the temperature constant in insulating box, and also there is amount of residual heat will in the hot-air of guide duct after inflow insulating box, last amount of residual heat will flows into the fresh air sent into pressure fan in heat exchanger and carries out heat exchange, and the fresh air after heat exchange enters in heater, is decreased the loss of heat by the mode of heat exchange;
(2) be provided with temperature measuring equipment in insulating box of the present utility model, the tail end of guide duct is also provided with magnetic valve; When the temperature that temperature measuring equipment measures in insulating box can not meet the requirements of time, control device can control the closed electromagnetic valve of guide duct afterbody, hot-air in such guide duct will all be filled in thermostat, ensure the temperature constant in thermostat, and when temperature is too high, opens solenoid valve the loss of heat will be reduced by the mode of heat exchange.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of fixed point heat-exchange device, comprises insulating box 1, heater 2, heat exchanger 3, pressure fan 4 and guide duct 5.
Wherein, described pressure fan 4 is connected with heat exchanger 3, and heat exchanger 3 is connected with heater 2, and described guide duct 5 one end is connected with heater 2, and the other end puts in insulating box 1, and after the inner wall surrounding of insulating box 1, stretches out insulating box 1 be communicated with heat exchanger 3; Described guide duct 5 has air outlet 6.
Wherein, be also provided with temperature measuring equipment 7 in described insulating box 1, the tail end of guide duct 5 is also provided with magnetic valve 8; Described temperature measuring equipment 7 is also connected with control device 9, described magnetic valve 8 controlled device 9 gauge tap.
Wherein, the external diameter of pipeline that described pressure fan 4 is connected with heater 2 with heat exchanger 3 and heat exchanger 3 is 2 times of guide duct 5 external diameter.
Wherein, magnetic valve 8 is also provided with between described pressure fan 4 and heat exchanger 3.
The utility model supplements new air by pressure fan to heater, after heater heating, hot-air enters in insulating box with guide duct, keep the temperature constant in insulating box, and also there is amount of residual heat will in the hot-air of guide duct after inflow insulating box, last amount of residual heat will flows into the fresh air sent into pressure fan in heat exchanger and carries out heat exchange, and the fresh air after heat exchange enters in heater, which reduces the loss of heat.
Be provided with temperature measuring equipment in insulating box of the present utility model, the tail end of guide duct is also provided with magnetic valve; When the temperature that temperature measuring equipment measures in insulating box can not meet the requirements of time, control device can control the closed electromagnetic valve of guide duct afterbody, and the hot-air in such guide duct will all be filled in thermostat, ensures the temperature constant in thermostat.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
