Example Embodiment

[0012] The present invention will be further described below in conjunction with the drawings.

[0013] As shown in the figure, an air duct heating device includes a heater 1, the heater 1 is fixed on the heating device bracket 2, wherein a waterproof junction box 3 is installed at both ends of the heater, and the back of the junction box 3 There is an outlet 31, the bracket is provided with a connection cavity 4, the junction box 3 is fixedly installed on the outer wall of the connection cavity 4, and the line exits the outlet 31 through the connection cavity 4, and then from the connection cavity 4 leads 41. Except for the lead 41, all the lines are hidden inside the frame to ensure electrical safety.

[0014] At the same time, the heater uses PCT thermistor as the material, which has fast heating speed, large heat dissipation area, and high conversion efficiency. With the increase of the use environment temperature, the energy consumption is automatically reduced, which improves...

Abstract

The invention relates to an efficient, energy-saving, safe and reliable air channel heating device which comprises heaters. The heaters are fixed onto a heating device support, waterproof junction boxes are mounted at two ends of each heater, a wire outlet is arranged on the back of each junction box, wiring cavities are arranged on the support, the junction boxes are fixedly mounted on the outer walls of the wiring cavities, and lines extend out of the wire outlets, pass through the wiring cavities and then are guided out of the wiring cavities. The air channel heating device has the advantage that except for parts which are guided out of the wiring cavities, all remaining portions of the lines are concealed inside a frame, so that the electric safety performance is guaranteed.

Description

technical field [0001] The invention relates to an air duct heating device, in particular to an auxiliary air duct heating device for air conditioning. Background technique [0002] Air duct electric heaters are used in industrial air ducts, air conditioning ducts and various industries to heat the air to increase the temperature of the output air. Generally, they are inserted into the transverse openings of the air ducts. The common feature in structure is that the electric heating tubes are supported by steel plates. In order to reduce the vibration of the electric heating tube, an over-temperature control device is installed in the junction box. In addition to the over-temperature protection, an intermodal device must be added between the fan and the heater to ensure that the electric heater starts. After the fan is started, a differential pressure device must be added before and after the heater to prevent the fan from malfunctioning. As a result, the structure of the a...
