Integral Internal Grooved Low Finned Tubes for Condenser

Application of Integral Internal Grooved Low Finned Tubes in Condensers

Integral finned tubes, also known as low-finned tubes or internally grooved tubes, are reinforced tubes. Fins are typically added to the surface of the heat exchange tube to increase its external (or internal) surface area, thereby improving heat transfer efficiency.

A condenser is a component of an air conditioning system that quickly transfers heat from the tubes to the surrounding air. Most cars have condensers located in front of the radiator. It is a device that converts gas or vapor into liquid.

Power plants use numerous condensers to condense turbine exhaust steam; refrigeration plants use condensers to condense refrigerant vapors such as ammonia and Freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation, the device that converts vapor into liquid is called a condenser. All condensers operate by removing heat from gas or steam.

Commonly used heat transfer finned tubes in condensers

The heat transfer process is the process of heat being transferred from one fluid to another through a solid wall. The heat transfer performance of the heat exchanger is mainly enhanced by enhancing the convective heat transfer process between the media on both sides and the inner and outer walls of the heat exchange tube.

Commonly used heat transfer enhancement technologies include:

(1) surface coating;

(2) rough surface;

(3) extended surface;

(4) various internal and external threaded tubes;

(5) turbulent elements;

(6) additives;

(7) impact heat transfer.

Application of Integral Internal Grooved Low Finned Tubes

Among various heat transfer enhancement technologies, adding fins to the wall is a major means of enhancing heat transfer and is widely used in engineering. Finned tube heat exchangers have the characteristics of high efficiency heat transfer and compact structure. They have been widely used in various fields such as refrigeration and air conditioning equipment, aerospace equipment, solar collectors and electronic equipment. Their application in condensers is particularly common.

Integral Internal Grooved Low Finned Tubes for Condenser

The turbulence caused by the rough surface of Integral Internal Grooved Low Finned Tubes destroys the static boundary layer, making it difficult for dirt to adhere;

If dirt adheres, it will also appear in the form of discrete scales. The temperature change during equipment operation causes the tube to expand and contract, which will cause peeling due to the huge expansion difference between the dirt and the tube wall material, and will fall off by itself under the impact of the medium.

The scale layer of smooth tubes is cylindrical and has no self-detachment force. The fouling of Integral Internal Grooved Low Finned Tubes is not much more serious than that of smooth tubes.
