Embodiment 1

[0039] Such as figure 1 - figure 2 As shown, this embodiment provides a heat sink, which includes an oil pocket structure 2 and a heat conduction oil passage 3 communicating with the oil pocket structure 2 , and also includes a through hole 4 and a heat insulation cavity 5 .

[0040] The heat sink is in the shape of a rectangular sheet with rounded corners, including a cavity 1. The cavity 1 is respectively provided with an upper cavity 11 and a lower cavity 12 along the height direction. The lower cavity 12 is connected with the heating rod for heat dissipation. The slices provide heat. An upper oil bag 21 is arranged along the peripheral side of the upper chamber part 11, and a lower oil bag 22 is arranged along the peripheral side of the lower chamber part 12. The heat conduction oil passage 3 communicates with the upper oil bag 21 and the lower oil bag 22. Heat transfer oil is provided in the oil bag 22 and the heat transfer oil passage 3 .

[0041] In this embodiment,...

Embodiment 2

[0053] This embodiment provides a heating element, including the heat sink and the heating rod provided in Embodiment 1. Several above-mentioned heat sinks are arranged side by side with each other, and the heating rod is penetrated at the position of the hole-shaped lower cavity portion 12 of each heat sink at the same time.

Embodiment 3

[0055] This embodiment provides an electric heater, including the heating element, temperature control element, indicator light, auxiliary device and other structures provided in Embodiment 2. Both the temperature control element and the indicator light are arranged on the heating body, and the indicator light is electrically connected with the temperature control element.

[0056] The auxiliary device includes but is not limited to: a clothes hanger, which is set above the heating body, and is suitable for drying clothes, etc.; it can also be a mobile bracket, which is set at the bottom of the heating body, and is used to support the heating body or drive the heating body to move. The mobile bracket itself can be a folding structure or an integrally formed structure. When the folding structure is used, it is convenient to reduce the space occupation when it is idle and improve the storage efficiency of the electric heater.

[0057] The electric heater is provided with a conv...

Abstract

The invention provides a radiating fin, a heating body and an electric heater. The radiating fin comprise an oil pocket structure and a heat conduction oil way communicating with the oil pocket structure, and further comprise through holes and a heat insulation cavity, wherein the through holes are arranged in an area between the heat conduction oil way and the edge of the radiating fin; and the heat insulation cavity is annularly arranged on the outer sides of the oil pocket structure and the heat conduction oil way in a surrounding manner. A heating rod heats the oil pocket structure, heat conduction oil in an oil pocket generates convection circulation along the heat conduction oil way, heat is radiated out through the radiating fin, the through holes are formed between the heat conduction oil way and the edge of the radiating fin, and the heat insulation cavity is formed between the oil pocket structure and the heat conduction oil way, so that the heat conduction coefficient from acenter high-temperature area of the heat conduction oil way position to the edge of the radiating fin can be changed, part of temperature transfer media are changed into air or other heat insulationmedia from metal, the heat conductivity is reduced, a heat insulation purpose is achieved, the temperature of the edge of the radiating fin is reduced, and a user is prevented from being scalded.

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] Electric heating oil heater is a safe and reliable space heater popular in recent years. This kind of heater usually installs the heating rod inside the cavity of the heat sink, and injects heat-conducting oil into the heat-conducting oil circuit around the cavity. When the power is turned on, the heat conduction oil around the heating rod is heated, rises to the upper part of the cavity, convects and circulates along the heat conduction oil circuit, and radiates heat through the surface of the heat sink, thereby heating the space environment. The air-cooled heat transfer oil descends along the heat transfer oil path to around the heating rod and is heated again, starting a new cycle. [0003] According to the current national standard, there are regulations on the temperature rise ...
