A high-efficiency heat exchanger with shy airfoil fins

Abstract

The invention discloses a sensitive type airfoil fin efficient heat exchanger, and belongs to the field of heat exchangers. The sensitive type airfoil fin efficient heat exchanger can change the angleof an airfoil fin of the heat exchanger according to the change of the temperature, the higher the heat exchanger temperature, the greater the degree of opening of the airfoil fin, the higher the heat exchange efficiency with another fluid, and the greater the degree of closure of the airfoil fin when the heat exchanger temperature is low or the heat exchanger is not in operation, so that the heat exchanger maintains the temperature of the surface of the heat exchanger for a certain period of time; the heat exchanger has a certain heat preservation effect, the temperature dissipation speed ofthe heat exchanger is slowed down, and heat exchanging of the heat exchanger is prolonged; and when the heat exchanger is in a stopped state, the airfoil fin is automatically adjusted to a closed state, an airfoil fin in the prior art maintains an opened state all the time, so that the possibility of scratching a user exists, and outside small objects are prone to attach to the space between thefins, and compared with the prior art, the airfoil fin of the heat exchanger has higher safety.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a shy airfoil-fin high-efficiency heat exchanger. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. In order to increase the heat exchange efficiency of the heat exchanger, circular airfoil fins are added to the outer ends of the heat exchange tubes of the heat exchanger in the prior art. The structural principle of the circular airfoil fins is: in order to improve the heat exchange efficiency, usually Fins are added to the surface of the heat pipe to increase the outer surface area (or i...

AI Technical Summary

Problems solved by technology

In the prior art, circular airfoil fins are added to the outer surface of the heat exchange tube to achieve the purpose of increasing the heat exchange efficiency of the heat exchanger. However, the circular airfoil fins in the prior art are welded and fixed during the production process. Therefore, the heat exchange efficiency of the heat exchanger cannot be adjusted by changing the circular airfoil fins. Therefore, if the heat exchange efficiency of the heat exchanger is improved, the production efficiency of more than 30 industries involved can be effectively improved, which has huge potential Economic benefits, and the airfoil fins of the heat exchanger in the prior art are always kept perpendicular to the heat exchange tubes, external dust or fine object particles are easy to adhere or get stuck on the airfoil fins, which will cause uneven heat transfer of the airfoil fins , prone to explosion
