Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating wires, in particular to a segmented anti-condensation heating wire. Background Art
[0002] As an innovative technical solution, the anti-condensation heating wire is designed specifically to address the condensation problems prone to occur in humid environments. It is made of special conductive materials to form a heating wire, which is ingeniously embedded in an insulating layer, a grounding layer, a shielding layer and an outer sheath to ensure safety while efficiently transferring heat energy. This kind of heating wire can be installed in areas vulnerable to condensation, such as inside cooling equipment, electronic equipment or optical instruments. By generating heat after being powered on, it can effectively maintain the surface temperature of these areas higher than the ambient dew point, thereby preventing water vapor from condensing, protecting the equipment from damage, and improving the operation stability and service life.
[0003] The heating principle of the heating wire is based on the thermal effect generated when current passes through a resistor. When current flows through the conductive material inside the anti-condensation heating wire, due to the resistance characteristics of the material itself, electrical energy is converted into heat energy, causing the temperature of the heating wire to rise. This process not only involves heat conduction, that is, directly transferring heat to the contacted surface through the heating wire, but may also be accompanied by far-infrared radiation, which can penetrate deep into the object to heat, further improving the anti-condensation effect. By precisely controlling the current magnitude and the power-on time, the heating wire can continuously and stably provide appropriate heat to ensure that the target area remains in a condensation-free state, providing a reliable guarantee for the stable operation of various equipment in humid environments.
[0004] The sealing ring of the cold cabinet door body is prone to aging in a continuous low-temperature environment, which will affect the sealing performance of the door body and cause frosting problems at the inner edge of the cold cabinet door body. In order to delay the aging process of the sealing ring, the main measure taken currently is to embed a heating wire in the cold cabinet door frame. When the cold cabinet is powered on and operates in the refrigeration mode, the heat generated by the heating wire can keep the environment around the sealing ring slightly warm, thus effectively slowing down its aging speed. However, within the framework of the existing technology, the design of the cold cabinet door frame usually involves filling foaming substances inside the door base frame. During this process, the heating wire and the foaming substances are often placed together inside the door base frame. As the foaming substances expand, they will fill the internal space of the door base frame, thereby fastening the heating wire to achieve its fixation.
[0005] However, this configuration method of the heating wire has a significant defect: once the heating wire fails, it will be difficult to disassemble, replace or repair it. Since the heating wire is tightly bonded to the foaming substances, if the heating wire is forcibly replaced, it will not only damage the structural integrity of the foaming filler, but may also cause deformation of the door base frame or make the heating wire unable to be effectively fixed.
