Radiating fin, heating body and electric heater

Abstract

The invention provides a radiating fin, a heating body and an electric heater. The radiating fin comprises an upper oil bag, a lower oil bag, at least one first pipeline and heat dissipation pipelines, wherein the first pipelines are used for containing heat conduction media and divide the radiating fin into at least two radiating areas with different horizontal heights in the vertical direction;and the heat dissipation pipelines are distributed in the radiating areas, the heat dissipation pipelines communicate with the first pipelines, the numbers of the heat dissipation pipelines in the adjacent radiating areas are different, and the number of the heat dissipation pipelines is relatively small in the radiating area with relatively high horizontal position. From the view point of the whole radiating fin, the temperature of the upper part of the radiating fin becomes relatively low, and the temperature difference between the upper part and the lower part of the radiating fin becomes smaller. At the moment, the heating power is continuously increased, a certain heating space is still arranged above the radiating fin, so that the temperature of the lower part of the radiating fin can be further increased, and the overall heating effect of the radiating fin is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a heat sink, a heating element, and an electric heater. Background technique [0002] Oil heaters are commonly used household heating equipment, such as figure 1 As shown, the existing electric heater usually includes a heat sink 1 and oil passages distributed on the heat sink 1 . The oil passage connects the upper oil bag 11 and the lower oil bag 12, wherein the horizontal position of the upper oil bag 11 is relatively high. There is a heat-conducting medium in the oil circuit, and the heating device is located in the lower oil bag 12 . [0003] When the electric heater is started, the heating device in the lower oil bag 12 heats the heat-conducting medium, and under the action of the density difference, the relatively high-temperature hot oil flows upward from the middle oil path, and the heat is transferred to the entire cooling system during the flow process. ...
