Radiators are important, essential components in hot water (or steam) heating systems. The hot water is cooled in the radiator (or the steam is condensed in the radiator) to supply heat to the room for heating purposes. The metal consumption and cost of the radiator occupy a considerable proportion in the heating system. Therefore, the correct selection of the radiator involves the economic indicators and operating effects of the system.
The higher the heat transfer coefficient of the same material Heat Sink
, the better the thermal performance. It can increase the heat dissipation area of the outer wall (with wings (ribs)), increase the flow speed of the air around the radiator (such as steel string radiators), and strengthen the radiation intensity of the outer surface of the radiator (such as the outer surface with emissivity) High coatings) and measures to reduce the thermal resistance of the heat sink by measures such as contact heat resistance between the various parts of the heat sink (such as the steel tube and string of steel string radiators).
The lower the cost of the heat sink unit (yuan/W), the lower the installation cost and the longer the service life, the better the economy. The higher the metal heat strength of the material heat sink (the heat dissipation per unit mass of metal and the heat transfer temperature difference per unit (the unit is W/(kg·°C))), the better the economy.
Installation and process requirements
The radiator should have certain mechanical strength and pressure bearing capacity, and should be easy to install and combine into the required heat dissipation area; the size should be small, occupying less room area and space; the installation and use process is not easy to break; the manufacturing process is simple and suitable Mass production.
Hygienic and aesthetic requirements
The surface of the radiator should be smooth and easy to remove dust; the shape should be beautiful and coordinated with the decoration of the room.
