Abstract

The invention discloses a preparation method of a heating pipe for a water radiating pipe detection device. The preparation method comprises the following steps of uniformly spraying acid fluid on theinner surface of a metal steel pipe, washing and drying to obtain a roughened steel pipe; adding phenolic resin into absolute ethyl alcohol, and uniformly stirring to form viscous fluid, so as to obtain phenolic resin viscous fluid; uniformly coating the rough surface of the steel pipe with the phenolic resin viscous liquid, and then extruding and flatly paving a phenolic foam board on the roughsurface at constant temperature to obtain a heat-insulating coated steel pipe; adding aluminum oxide into the phenolic resin viscous liquid in the step 2, and carrying out ultrasonic dispersion to obtain suspended viscous liquid; and flatly paving a graphene fiber net on the inner surface of the steel pipe, and then coating the surface of the graphene fiber net with the suspension viscous liquid to obtain heating pipe through constant-temperature extrusion reaction for 2 to 4h. According to the preparation method of the heating pipe for the water radiating pipe detection device, the problem ofnon-uniform local temperature is solved, the graphene is used as a heating layer to form a uniform discharge net, and meanwhile, the temperature uniformity is realized by using the high heat conductivity coefficient of the graphene.

Description

technical field [0001] The invention belongs to the field of heat dissipation of solar backboards, and in particular relates to a method for preparing a heating pipe used in a water heat dissipation pipe detection device. Background technique [0002] At present, the commonly used solar cell backsheet is mainly TPT backsheet. On the one hand, the price is relatively high. In addition, it uses a large amount of polymer resin with very poor thermal conductivity, which cannot effectively export the heat generated by the solar cell. It is used in photovoltaic modules. The limitations of the performance are becoming more and more prominent. In order to timely and effectively export the heat in the solar cell module, the main way at present is to select a metal material with high thermal conductivity as the solar cell backsheet. However, due to the strong absorption capacity of metal materials for near-infrared spectrum, the temperature rises faster after metal materials with low...
