Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical technology, specifically to a fixing device for an electric heating unit in a solar water heating system. Background Technology
[0002] The existing fixing device for the electric heating unit of the solar water heating system has a plate-shaped fixing plate with holes. When water passes through the fixing plate, it will stagnate at this point, and scale will form on the fixing plate over time, which will burn out the electric heating unit. To solve the above problems, we have designed a fixing device for the electric heating unit of the solar water heating system. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fixing device for the electric heating unit of a solar water heating system. The technical solution adopted by this utility model to solve its technical problem is: a fixing device for the electric heating unit of a solar water heating system, including an electric heating unit, a heating resistance rod, and a fixing plate, characterized in that the heating resistance rod passes through the electric heating unit, and a fixing plate is provided inside the heating resistance rod.
[0004] Preferably, the fixing plate is made of stainless steel wire, and the fixing plate is formed by cross-winding stainless steel wire around a heating resistance rod.
[0005] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0006] The fixing device of the electric heating unit of the solar water heating system of this utility model uses stainless steel wire to cross-wrap the heating resistor rod multiple times. While fixing the heating resistor rod, it increases the water flow. When the water passes through the fixing plate, it will not stagnate at this point, and scale will not form on the fixing plate, thus extending the service life of the electric heating.
