Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model are within the protection scope of the present utility model.
Referring to fig. 1 to 4, an outdoor installation type intermittent air heater comprises a shell 11, and a combustion fan 13, a heat exchange fan 12, a combustor 14 and a heat exchange tube 15 which are arranged in the shell 11, wherein one end of the heat exchange tube 15 is connected with the combustor 14, the other end of the heat exchange tube is connected with the combustion fan 13, the shell 11 is also provided with a smoke exhaust tube 2, the smoke exhaust tube 2 is communicated with the combustion fan 13, the heat exchange fan 12 faces the heat exchange tube 15, one side of the shell 11 is provided with an air return opening 3, the other side of the shell 11 is provided with an air outlet 4, and the heat exchange fan 12 blows air entering from the air return opening 3 to the heat exchange tube 15 and then discharges the air from the air outlet 4.
Preferably, the heat exchange tube 15 is arranged in a serpentine shape.
Further, return air inlet 3 is connected with return air pipe 5, air outlet 4 is connected with out tuber pipe 6, return air pipe 5, play tuber pipe 6 all communicate with outside wall body.
The system (roof installation is exemplified) consists of an outdoor-installed indirect-combustion warm air blower device, an installation bracket 7, a return air pipe 5, an air outlet pipe 6, a single-layer shutter return air inlet 3, an injection type air outlet 4 and the like. The system is installed on an outdoor roof of a building, and can also be installed around the outside of the building, and the system is installed on the outdoor roof for example: because the density of the hot air is smaller, the hot air finally runs to the indoor upper side, the air return opening 3 shutter is positioned on the roof, and the hot air is pumped into the equipment through the air return pipe 5 under the action of the heat exchange fan 12 on the intermittent combustion fan heater equipment. The heat exchange fan 12 blows the air to the serpentine heat exchange tube 15 for heat exchange, and finally hot air is generated, and the hot air is blown to the ground through the air pipe and the jet nozzle of the air outlet 4. Through the continuous circulation heating of indoor air, the hot air above the indoor is blown out after being heated, so that the upper temperature and the lower temperature in the building are more uniform, the heat above the indoor is further utilized, and the energy is saved.
In addition, the intermittent combustion fan heater equipment is arranged outdoors, so that the related cost for installing a fuel gas leakage alarm is saved, the safety accidents caused by fuel gas leakage are eliminated from the source, and meanwhile, the flue gas of the intermittent combustion fan heater is discharged outdoors, so that the safety accidents caused by carbon monoxide in the flue gas indoors are avoided.
The working principle of the utility model is that the ignition is carried out under the action of the control system, the valve 8 of the gas valve is opened, and the gas enters the burner 14 through the gas pipe to ignite the fire. The serpentine heat exchange tube 15 is heated by flame and high-temperature flue gas, and the flue gas is discharged outdoors through the combustion fan 13 and the smoke exhaust tube 2. The heat exchange fan 12 blows air to the surface of the serpentine heat exchange tube 15, and blows out the generated heat in a warm air manner. Compared with the traditional combustion water heat exchange, the heat loss of water heat exchange is saved, a water circulation system such as a water pump is not needed, and later scale maintenance is also carried out.
The serpentine heat exchange tube 15 is used for flushing high-temperature flue gas in the tube to heat the tube. The heat exchange tube is made into a snake shape, mainly for increasing the heat exchange area and increasing the resistance, so that the temperature of the tube is raised faster, and the heat exchange efficiency is improved.
The heat exchange fan 12 adopts a positive pressure air supply mode, so that the heat exchange fan 12 operates at normal temperature, and the influence of high temperature on the performance and the service life of the fan is avoided. In the figure, the fan is an axial flow fan, and in addition, a centrifugal fan with larger wind pressure can be adopted by considering the air supply distance.
Depending on the thermal power of the device, 1 or 2 or more combustion fans 13 and heat exchange fans 12 may be used.
The air outlet pipe 6 and the return air pipe 5 are respectively connected with the air outlet 4 and the return air inlet 3 of the intermittent air heater. The indoor shutter return air inlet 3 is used for preventing foreign matters from entering the equipment. The air outlet 4 adopts a jet nozzle to blow the heat to the ground as far as possible.
The above description is only of the preferred embodiments of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
