Abstract
The invention discloses a fixed point heat exchange device which comprises a constant temperature box, a heater, a heat exchanger, an air feeder and an air guide guide, wherein the air feeder is connected with the heat exchanger; the heat exchanger is connected with the heater; one end of the air guide pipe is connected with the heater; the other end of the air guide pipe stretches into the constant temperature box, surrounds the inner wall of the constant temperature box and then stretches out of the constant temperature box to be communicated with the heat exchanger; an air outlet is formed in the air guide pipe. New air is supplemented to the heater through the air feeder, and after new air is heated by the heater, hot air enters the constant temperature box along with the air guide pipe, so that the temperature in the constant temperature box keeps stable; in addition, the hot air of the air guide pipe has residual heat after flowing into the constant temperature box, the final residual heat flows into the heat exchanger to exchange heat with fresh air fed by the air feeder, and fresh air subjected to heat exchange enters the heater, so that hot loss is reduced through a heat exchange mode.
Description
Technical field
The present invention 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.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention 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 present invention has the following advantages:
(1) the present invention 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 invention, 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 structure chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention 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 present invention 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 invention, 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
