The utility model is realized by following measure:
A kind of air heat unit of the present utility model, comprise shell, the air heater that is positioned at shell air outlet place that is provided with air inlet and air outlet, the blower fan that is positioned at air heater offside air inlet place and the controller of housing exterior, described air heater is provided with heating agent import and heating agent outlet, the heating agent outlet of described air heater is provided with temperature sensor and frost valve, the switching of control frost valve is provided with the heat pipe heater that is connected with the heating agent import behind the transducing signal of described controller reception temperature sensor in the described shell.
Air heat unit of the present utility model, described side wall of outer shell for the sealing and sidewall be provided with access door.
Air heat unit of the present utility model, the sidewall of described air inlet place shell are provided with some blast and regulate mouth.
Air heat unit of the present utility model, heat pipe heater is made up of one group of heat pipe and is arranged between air heater and the blower fan.
Air heat unit of the present utility model, the outside of described air inlet, air outlet and shell is provided with the temperature sensor that is connected with controller.
Air heat unit of the present utility model, described frost valve are magnetic valve.
Air heat unit of the present utility model, described air inlet and air outlet place are provided with screen pack.
The beneficial effects of the utility model are: heat pipe heater increase to be installed, to be improved approximately 10% ~ 15% than the conventional air firing equipment thermal efficiency, it is about 10% ~ 15% that heat transfer coefficient improves, energy savings about 15% ~ 30%; Frost valve is installed in air heater heating agent outlet, can discharge the heating agent that remains in the air heater when certain low temperature, avoids the heating agent freezing air heater that freezes; At side wall of outer shell access door is installed, is made things convenient for the repair and maintenance of blower fan, heat pipe heater and air heater; On the sidewall of air inlet place shell, pressure modulating opening is installed, is realized that the air feed blast is adjustable, changed the single of blast.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 base, 2 intake air temperature sensors, 3 blower fans, 4 air inlets, 5 blast are regulated mouth, 6 shells, 7 heat medium enter hoses, 8 electric control valves, 9 heat pipe heaters, 10 air heaters, 11 air outlet temperature sensors, 12 air outlets, 13 mix wind-warm syndrome degree sensor, 14 heat medium outlet temperature sensors, 15 frost valves, the outlet of 16 heating agents, 17 access doors, 18 switch boards, 19 variable-frequency governors.
The specific embodiment
As shown in Figure 1, the unit of this air heat shown in the figure, comprise base 1, shell 6 is installed on the base 1, air inlet 4 and air outlet 12 are set on the shell 6, air heater 10 is installed at air outlet 12 places in the shell 6, blower fan 3 is installed at air heater 10 offside air inlets 4 places, air heater 10 is provided with heating agent import that is communicated with heat medium enter hose 7 and the heating agent that is communicated with heat medium produce hose outlet 16 with heat pipe heater 9, electric control valve 8 is installed on heat medium enter hose 7, and electric control valve 8 is connected with switch board 18 by circuit.The heat pipe heater of being made up of one group of heat pipe of combining 9 is installed between air heater 10 and blower fan, and heat medium enter hose 7 and heating agent import also are connected with heat pipe heater 9 simultaneously.Shell 6 outer setting controllers 18, electric elements and the variable-frequency governor 19 installed in the controller 18 are known technology.The heating agent outlet 16 of air heater 10 is provided with heat medium outlet temperature sensor 14 and the frost valve 15 that is connected with controller 18, frost valve 15 adopts magnetic valve, controller 18 receives the switching of control frost valve 15 behind the transducing signal of heat medium outlet temperature sensor 14, and then realizes the switching of control heating agent opening.On sealing of shell 6 sidewalls and the sidewall access door 17 is set, devices such as convenient maintenance air heater 10, heat pipe heater 9, blower fan 3.Some blast are set on the sidewall of air inlet 4 place shells 6 regulate mouth 5.EAT sensor 2 is installed at air inlet 4 places, leaving air temp inductor 11 is installed at air outlet 12 places, mix wind-warm syndrome degree sensor 13 shell 6 outside installations, EAT sensor 2, leaving air temp inductor 11, mixing wind-warm syndrome degree sensor 13 go out temperature sensor 14 with heating agent and all link to each other with controller 18.The safety filtering net is installed at air inlet 4 and air outlet 12 places at shell 6.
