Energy-saving radiator with good dust filtering effect and based on thermal expansion and cold contraction principle

Abstract

The invention relates to the technical field of energy-saving radiators, and discloses an energy-saving radiator with a good dust filtering effect and based on a thermal expansion and cold contraction principle. The energy-saving radiator comprises a rack; the interior of the rack is movably connected with a ventilation turbine; the inner wall of the ventilation turbine is fixedly connected with a conical booster pipe; the right wall of the conical booster pipe is inserted with a cold air outlet pipe; the opposite end of the cold air outlet pipe is fixedly connected with a ventilation pipe; and the inner wall of the ventilation pipe is movably connected with a driving shaft. According to the energy-saving radiator with the good dust filtering effect and based on the thermal expansion and cold contraction principle, hot air in the radiator to be cooled is pumped out through the ventilation turbine, the hot air rotates at a high speed in the conical booster pipe and continuously expands after being preliminarily accelerated by the ventilation turbine, and cold air is exhausted from the cold air outlet pipe; and under the action of a cooling turbine, the air is blown to the surface of a to-be-radiated tool through the ventilation pipe, so that the convection speed of the air is increased, the heat exchange efficiency of internal hot air and external cold air is improved, and the radiating effect is better.

Description

technical field [0001] The invention relates to the technical field of energy-saving radiators, in particular to an energy-saving radiator with good dust filtering effect based on the principle of thermal expansion and cold contraction. Background technique [0002] Radiator refers to the device or instrument that transfers the heat generated by machinery or other appliances in the working process in time to avoid affecting its normal operation. Common radiators can be divided into air cooling, heat pipe radiators, liquid cooling, and semiconductor radiators according to the cooling method. Refrigeration, compressor refrigeration and other types. [0003] Traditional air-cooled radiators mostly use a motor-driven cooling fan to blow the equipment that needs to be cooled to dissipate heat. Due to the low efficiency of heat exchange, the heat dissipation effect is poor, and the traditional air-cooled radiator sucks the cold air from the outside into the equipment. A large amo...
