Efficient energy-saving electrical oil heater

Abstract

The invention provides an efficient energy-saving electrical oil heater. The efficient energy-saving electrical oil heater comprises a base, a pipeline unit, a plurality of heat sinks and a control unit, wherein the pipeline unit is arranged on the base, the pipeline unit forms a ring shape in a surrounding mode, the heat sinks are installed on the pipeline unit in a rotary mode along the ring shape, the control unit comprises a rotary rod, a control block and a plurality of connecting rods, the rotary rod is arranged on the base in a rotary mode, a rail is arranged on the side wall of the rotary rod, the rail extends upwards in a spiral mode along the side wall of the rotary rod, the control block is arranged on the rotary rod in a sleeving mode, and the control block extends towards the rail to form a clamping block so that the control block can move up and down when the rotary rod rotates; one end of each connecting rod is hinged to the control block, and the other end of each connecting rod is hinged to the corresponding heat sink; when the control block moves to the lowermost end of the rail, the heat sinks rotate outwards to be totally open; when the control block moves to the uppermost end of the rail, the heat sinks rotate inwards to be totally closed.

Description

technical field [0001] The invention relates to the field of electric heaters, in particular to a high-efficiency and energy-saving electric heating oil heater. Background technique [0002] Electric oil heater, also known as oil-filled heater, is a safe and reliable space heater that is currently popular. This kind of heater is generally equipped with a bimetal temperature control element. When the oil temperature reaches the set temperature, the temperature control element will automatically cut off the power supply. When the power is turned on, the heat transfer oil around the electric heating tube is heated and rises to the upper part of the cavity, convectively circulates along the heat dissipation tube or heat sink, and radiates heat through the cavity wall surface, thereby heating the space environment. The heat transfer oil cooled by the air descends to the electric heating tube and is heated again to start a new cycle. [0003] Traditional oil-filled heaters use s...

AI Technical Summary

Problems solved by technology

[0003] Traditional oil-filled heaters use side-by-side heat sinks as the main body of heat dissipation. Through the flow of heat transfer oil inside the heat sink, the heat from the heating pipe at the bottom is transferred to the entire heat dissipation body, and through natural convection heat exchange, the overall heating of the environment is realized. This type of oil-filled heater has a single appearance, slow heat dissipation effect, and low heating efficiency
