A radiant fin tube is a key conduit in a radiator system used for heat transfer. Its core function is to achieve the efficient transfer of heat energy from the heat source to the environment (or cooling medium), thereby maintaining the temperature stability of the equipment or space.

Types and Functions of Radiant Fin Tubes in Different Scenarios

The form, material, and function of radiant fin tubes vary depending on the application scenario (e.g., industrial, residential, automotive, refrigeration equipment, etc.).

1. Automotive Radiant Fin Tube

Automotive radiator tubes generally use copper finned tubes and are the core heat exchange component of the engine cooling system, consisting of “tubes + fins”:

Tubes: Responsible for transporting coolant (such as antifreeze), transferring the heat generated by the engine to the fins;

Fins: Significantly increase the heat dissipation surface area, allowing the heat from the coolant to be efficiently transferred to the flowing air, achieving engine cooling.

These types of pipes must meet requirements such as high temperature resistance, corrosion resistance, and vibration resistance to adapt to the automotive operating environment.

2. Radiant Fin Tube

Radiator pipes, typically spiral-finned, are the heat transfer medium in indoor heating systems, commonly found in cast iron and steel radiators:

Pipes: Transport hot water or steam, transferring heat from a heat source (such as a boiler) to the radiator;

Radiator (including pipes): Through the connection between the pipes and the radiator, heat is released into the indoor air, raising the ambient temperature.

These pipes must be pressure-resistant and corrosion-resistant to withstand the high temperature and high pressure conditions of hot water/steam.

3. Radiant Fin Tubes for Refrigeration Equipment (e.g., freezers)

Radiant fin tubes for refrigeration equipment typically use low-finned tubes and serve as the channel for heat transfer in the refrigeration system. They are commonly found in freezers, refrigerators, etc.:

Pipes: Transport refrigerant (e.g., Freon), transferring the heat generated by the refrigerant during compressor compression to the radiator;

Radiator (including pipes): Through the cooperation of the pipes and the radiator, release heat to the external environment, maintaining the low temperature inside the refrigeration equipment.

These pipes must possess characteristics such as low-temperature resistance, hydrolysis resistance, and aging resistance to adapt to the special operating conditions of the refrigeration system.

4. Radiant Fin Tube (Special Heat Exchange Technology)

Heat pipe radiators are high-efficiency heat exchange components based on heat pipe technology:

Heat pipe structure: Generally made of carbon steel and stainless steel, it achieves long-distance heat transfer through a cycle of liquid evaporation absorbing heat and gas condensation releasing heat.

Working principle: One end connects to a heat-generating element (such as a chip in an electronic device), and the other end connects to a radiator. Heat is efficiently transferred to the radiator through the heat pipe, and then released to the environment by the radiator.

This type of pipe utilizes the high thermal conductivity of heat pipes to achieve the goal of “small volume, high heat dissipation” in heat exchange.

The Radiant Fin Tube is the core carrier of heat transfer in a radiator system. Its type, structure, and function vary depending on the application scenario (automotive, heating, refrigeration, heat pipes, etc.), but the core logic always revolves around “efficiently transferring heat energy from the heat source to the environment.”
