Detailed ways

The technical solutions of the present application are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

In order to dry towels and clothes, the most commonly used method at present is the water-injection heating tube, that is, a heat-conducting liquid (usually water) is passed into the metal coil for heat conduction, and liquid is used as the heat transfer medium, which not only has a slow heat conduction speed, And often there will be uneven heating and cooling. If the temperature is not well controlled, it will cause burns to the human body. In addition, due to the long-term contact between the heat transfer liquid and the metal coil, the metal coil will be oxidized and rusted, and there is a risk of heat transfer fluid leakage. Therefore adopt above-mentioned method, all there is very big deficiency no matter drying effect or safety.

Another heating method is carbon fiber heating. In the energized state, carbon fiber heating wires are used for drying, which overcomes the shortcomings of water injection heating and is easy to corrode, and improves the shortcomings of water injection heating unevenness to a certain extent. However, carbon fiber heating wire is a carbon fiber composite material combined with epoxy resin and carbon fiber. The resin matrix plays a decisive role in the heat resistance of the composite material. The stability of the composite material will decrease during the long-term humid heat aging process. That is to say, in a long-term humid and hot environment, the thermal fusion, density, thermal expansion coefficient, and electrical conductivity of the carbon fiber heating wire will change drastically. Therefore, the use of carbon fiber heating will face the problem of equipment heating power decline. On the other hand, the carbon fiber heating method is also based on the tubular shape. The carbon fiber heating wire is inserted into the tube. The temperature of the carbon fiber heating wire near the tube wall is high, and the temperature away from the tube wall is low, so there is also uneven heating and cooling. question.
