Copper indium gallium selenide (CIGS) thin film solar cell air heater

Abstract

The invention discloses a copper indium gallium selenide (CIGS) thin film solar cell air heater. An inclining cold air inlet is formed in one corner of the top end of a cylinder type metal shell drum, and an extending or metal-flexible-pipe-structure heated air connecting pipe is arranged in one corner of the bottom end of the metal shell drum; heat insulating bricks are arranged on the inner side of the metal shell drum in an arrangement distribution mode, a heating element is vertically arranged in a cavity formed in the inner side walls of the heating insulating bricks, the outer sides of the two ends of the heating element are connected with a power source connecting wire, and the shape of the heating element is of a spiral inner hollow structure; a filling type structure in a gap of the periphery of the heating element is provided with a ceramic fiber heat insulating layer; and a layer of CIGS thin film solar cell covers the outer side of the metal shell drum. The CIGS thin film solar cell air heater is novel in structure, reliable in principle, safe in using operation, saving in electricity energy, good in construction environment and high in heating efficiency.

Description

technical field [0001] The invention relates to an air heater, in particular to a CIGS thin film solar cell air heater. Background technique [0002] At present, the air heater is an important part of the cold spray equipment, which determines the performance and processing capacity of the equipment. Usually, for cold spray equipment with a heater that can reach 300 degrees Celsius, the materials that can be processed are mainly limited to aluminum and lead; when it reaches 500 degrees Celsius, it can process copper, titanium, stainless steel and other materials; when it reaches 800 degrees Celsius, it can process MCrAls, Co- WC and other high hardness materials. However, the high temperature means higher requirements on the service life and protection measures of the equipment, resulting in bulky heaters or inconvenient installation and operation. The electric heater produced by CGT Company, whether it is to heat the gas temperature to 500 degrees Celsius or above 800 deg...

AI Technical Summary

Problems solved by technology

For portable heaters, the weight of the spray gun is more than 20kg, which cannot be hand-held, and the temperature of the outer surface of the spray gun is at least 100 degrees Celsius, which requires high protection. The utilization efficiency of heat is low, and for the air heater, because it needs to be heated to a high temperature, the problem of high energy consumption is also another problem restricting its development.
