Plastic radiating and ventilating water heater and making method thereof

Abstract

The invention relates to a plastic radiating and ventilating water heater used in the field of heating and bath radiating and ventilating water heaters adopting hot water as a heat medium and relates to a method for making the radiating and ventilating water heater and a material thereof. The plastic radiating and ventilating water heater comprises an injection-molded structure or a molded sectional material and is characterized in that a coaxial heat exchanger is provided with heating medium channels and heated medium channels; a plurality of heat exchange pipes and a plurality of heated medium pipes are axially arranged in a sleeving way, the pipes with a bigger diameter are arranged outside the pipes with a smaller diameter in a sleeving way, and the heated medium pipes are arranged on the outermost layer; lock catch grooves of the heated medium channels and the heat exchange pipes, which are connected in series and communicated are fixedly connected with heat exchange abnormal pipes in a way of directly plugging in built-in lock catches and bonding under a heated condition, or in a way of directly plugging in the built-in lock catches and bonding with a glue solution, or in a way of direct-plug-in heated bonding and glue solution bonding; or the lock catch grooves and the abnormal heat exchange pipes are injection-molded into a whole by a die. The plastic radiating and ventilating water heater belongs to a novel radiating and ventilating water heater which can avoid oxidation or alkali corrosion problems, has excellent heat radiation and conduction properties and long service life, and can overcome the defect that the environment is worsened by the water quality of the heat medium.

Description

technical field [0001] The invention relates to a plastic radiator water heater, its material and a method for preparing the radiator water heater, which are applied in the field of radiator and water heaters for heating and bathing with hot water as the heat medium. Background technique [0002] The existing radiator water heaters for heating are mostly made of various metal materials, which have high energy consumption, high construction cost, complicated preparation process, easy to be corroded, poor pipeline integrity, and easy leakage. Copper and steel radiator water heaters are used in Most of the heating systems in northern my country currently have a service life of about 3-5 years under the conditions of use, which does not meet the requirements of the 15-year service life required by the Radiator Industry Committee of the Ministry of Housing and Urban-Rural Development. Since the mid-20th century, countries around the world, especially developed countries, have been...
