Fluid state energy-saving heater

Abstract

The invention discloses a fluid-state energy-saving heater which comprises a case, a ring-shaped radiator, an air-guide spiral case, a rotating frame, a magnetic guide wheel, a low-speed motor, a blower motor, a centrifugal wind wheel, an oil-heating electric heater and a bearing. The heat-transfer oil pipe of the ring-shaped radiator is filled inside with heat-transfer oil. Fins are arranged outside the heat-transfer oil pipe to enhance heat dissipation. The heat-transfer oil pipe communicates with the oil-heating electric heater. Under the condition that the ring-shaped radiator rotates, the heat-transfer oil is in fluid state. The temperature difference between the fluid-state heat-transfer oil and the surface of electrically-heating tube of the oil-heating electric heater is large. Therefore, the fluid-state energy-saving heater has good heat-transfer property and realizes heat dissipation and heat supply under the condition of forced air convection of the centrifugal wind wheel.

[0002] Existing electric heating equipment mainly includes (heat transfer oil heat transfer) electric heating oil heater, halogen lamp, carbon fiber heater, resistance wire heater, quartz lamp tube, etc., carbon fiber heater, quartz lamp tube, halogen lamp directly Radiation can cause discomfort to the human body, and it can also accelerate the aging of items around the heat radiation. A heater that overcomes radiation defects - an electric oil heater (heat transfer oil heat transfer) heater, uses the inner surface of the metal plate type oil tank An electric heating tube is installed at its low position, and the electric heating tube is used to transfer heat to the heat transfer oil. When the oil temperature rises to a certain level (usually 120°C), it boils, and the boiling oil expands the heat transfer area in the plate-type oil tank, making it more efficient. Many heat transfer surfaces dissipate heat to the surroundings, and the heat dissipation method mainly relies on natural convection heat transfer. When in use, the temperature near the electric heater is high, and the farther away from the electric heater, the worse the heating effect. This natural convection heating cannot make the indoor temperature uniform , in order to effectively make the entire room meet the heating requirements, consumers will choose higher power specifications, but this will increase the electrical load and waste energy

Electric heating oil also has vapor pressure formed after the oil temperature is too high. When the steam pressure exceeds the welding strength of the metal plate, there may be a danger of bursting. The surface temperature of the electric heating oil plate is usually 90 ° C ~ 120 ° C. It is used as a household It is not very safe, and it is easy to burn if you use it carelessly
