Description

A phase change radiator

technical field

The utility model belongs to the technology of heating equipment, in particular to a phase change radiator.

Background technique

At present, most heating equipment uses traditional water heating radiators, with hot water or steam as the heat transfer medium. Hot water or steam flows through the radiator, and then the radiator dissipates heat into the air to achieve the purpose of heating. This method not only has low heat transfer efficiency, but also consumes a lot of energy and water resources, and the life of the radiator is short. .

At present, there are many kinds of vacuum phase change radiators used for heating on the market. The structural principle is to set the heat dissipation working medium in the vacuum chamber, and set the heat source tube in the heat dissipation working medium. When the heat source working medium enters the heat source tube from the inlet, The heat dissipation working medium is heated and vaporized to fill the entire vacuum cavity, making the radiator shell heat up, thereby achieving the purpose of heat dissipation and heating. This kind of radiator is characterized by high thermal efficiency, material saving, and long service life, but its disadvantage is that the heat medium pipe is a straight pipe, and when the heat source working fluid flows in the pipe, a typical laminar flow boundary layer is formed, which affects the heat source work. Heat exchange between fluid and cooling fluid.

The cast iron radiator is bulky and consumes a lot of energy, which does not meet the purpose of energy saving. The oxygen corrosion problem of steel radiators is serious, and the alkali corrosion problem of aluminum radiators cannot be solved. Both radiators need to improve internal anti-corrosion technology. The copper-aluminum composite radiator uses copper tubes as the water-holding parts to solve the corrosion problem; uses aluminum profiles as the heat-dissipating parts to solve the bulky problem. It is a new product suitable for residential use requirements.
