Electrical oil heater

Abstract

The invention provides an electrical oil heater. The heater comprises a plurality of heater body pieces and oil way channels, wherein the heater body pieces comprise an upper oil bag and a lower oil bag, and a heating part is arranged in the lower oil bag; the oil way channels are distributed on the heater body pieces and are used for communication between the upper oil bag and the lower oil bag,the number of the oil way channels varies, and the number of the oil way channels corresponding to the part close to the upper oil bag in the height direction is small; and / or, in the height directionof the heater body pieces, values of the distance M from the oil way channels close to the edges of the heater body pieces to the edges vary, and the values of the M corresponding to the oil way channels close to the upper oil bag is large. Heat is transferred through the upper oil bag and the oil way channels to the entire heater body piece range. When the M values are increased, the distance between the oil way channels and the edges is increased, and the efficiency of heat transfer to the edges is low. When the number of the oil way channels is reduced, the heat transferred by the oil waychannels to the heater body pieces in unit time in the same environment becomes less, the heat transfer efficiency is low, so that temperatures of the edges during are lowered.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric heating oil heater. Background technique [0002] Electric heaters have been widely used in homes, hotels and other places due to their advantages of portability and ease of use, especially in places where the south is humid and cold in winter and there is no heating, and they are used in a wide range of places. [0003] Electric oil heaters, also known as oil heater electric heaters, are common electric heaters. Oil heater electric heaters include multiple heater body structures, which include upper and lower oil bags, and oil distributed on the heater sheets. There is heat transfer oil in the upper and lower oil bags and the oil circuit. After electrification, the heating body heats the heat transfer oil, so that the heat transfer oil transfers heat to the body structure, and then transfers the heat to the surrounding environment. [0004] However, wh...
