Hot Air Heating Device Saves Energy
Jun 14, 2017


The hot air heating device is characterized in that it comprises a box, the upper cover of the box has a hole, the box is provided with a heating device, and the heating device is provided with a blowing device, which blows the wind to the heating device , In the box with the heating device to form a round of hot air, the heat emitted by the box through the hole with the cover to the PCB to be printed. Hot Air Heating Device The invention has the advantages of simple structure and convenient use, and can guarantee the heating temperature of the PCB board to the appropriate temperature and improve the welding yield of the PCB board. As the insulation cotton is installed in the box, it can effectively prevent the loss of heat and save energy.

The hot air heating device is characterized in that it comprises a box, the upper cover of the box has a hole, the box is provided with a heating device, and the heating device is provided with a blowing device, which blows the wind to the heating device , In the box with the heating device to form a round of hot air, the heat emitted by the box through the hole with the cover to the PCB to be printed. The invention has the advantages of simple structure and convenient use, and can guarantee the heating temperature of the PCB board to the appropriate temperature and improve the welding yield of the PCB board. As the insulation cotton is installed in the box, Hot Air Heating Device it can effectively prevent the loss of heat and save energy. The temperature of the heating gas existing in the prior art is fluctuated, and the temperature can not be kept constant. The heating gas can be used for a long time to stabilize the supply, Hot Air Heating Device and the temperature is maintained within the specified temperature range, the supply of gas temperature, flow, pressure can be adjusted.

The technical scheme of the utility model is

Hot air heating device The device is provided with a closed cavity, a gas pipeline, a heater, a discharge pipe, a heater is arranged in the closed cavity, the airway is wound on the heater and the gas inlet of the air duct extends out of the closed cavity The outlet of the pilot line is provided in the closed chamber and the gas discharge port of the discharge line extends into the closed chamber.

The hot air heating device is provided outside the device, Hot Air Heating Device and the temperature sensor is provided with a temperature sensor connected with the temperature display.

The hot air heating device is provided with a temperature controller connected to the heater. The hot air heating device and the outer side of the closed cavity are provided with an external heat insulating layer. The hot air heating device is provided with a pressure regulating valve and a unidirectional conducting valve on the pipeline before the gas inlet. The hot air heating device and the discharge pipe are provided with a flow meter. The advantages and advantages of the utility model are

The utility model adopts a heat conduction fast gas pipeline closely wound on a heater and then installed in a sealed cavity, and the supplied gas is heated by a gas pipeline and discharged into a sealed cavity of constant temperature, The temperature is provided by the heating of the heater. The heating of the gas is carried out by heat conduction through the air ducts wound on the heater. The gas is heated by heating, circulated and closed. Hot Air Heating Device The temperature is set at a temperature, Pipeline to the need to supply the place, to ensure that the temperature is constant and accurate.

The temperature of the heating gas of the utility model device is directly detected by the temperature sensor at the gas outlet, and the temperature of the temperature is controlled by the temperature controller, and the temperature of the heated gas is through the closed chamber Body temperature regulation after discharge. When the temperature is above or below the set temperature range, the temperature sensor sends a signal to the temperature controller, the temperature controller drives the heater to work or stops working, and the heating frequency of the heat exchanger is controlled by the temperature controller, Heating the temperature of the gas, thus ensuring the temperature of the exhaust gas is constant, its operation is simple and flexible, easy to adjust the process.
