Abstract

An instant heating electric heater includes a heat sink, the heat sink includes a plurality of heat sinks connected in sequence, the heat sinks include a first heat sink single piece and a second heat sink single piece that are buckled and connected together, and the third heat sink single piece An insulated electric heating cord is disposed between one heat dissipation single piece and the second heat dissipation single piece, and an insulated electric heating cord is disposed between the first heat dissipation single piece and the second heat dissipation single piece, which is opposite to the layout track of the insulated electric heating cord. The matched flexible wire channel is provided with heat-insulating hollow ribs and heat-insulating holes near the edge of the heat sink. Compared with the existing technology, the instant electric heater provided by the present invention has the following advantages: the arrangement of the heat-insulating hollow ribs and heat-insulating holes can prevent the temperature of the outer surface that can be contacted by the human body from rising beyond the national standard of 85K, and prevent the human body from touching the Be burned; so that the insulated electric heating cord in the heat sink can be heated at the nominal power for a long time without worrying about the temperature at the edge of the heat sink being too high; it can maximize the nominal power of the insulated electric heating cord.

Description

technical field

[0001] The invention relates to an electric heater, in particular to a fast heating electric heater. Background technique

[0002] The current electric heaters are roughly divided into the following types: 1. Electric heating oil heaters are generally assembled from multiple heat sinks. At the same time, a cavity is formed in each heat sink, and the heat conduction oil is filled in it. The electric heating element is soaked in heat transfer oil, and the heat is transferred by heating the heat transfer oil. 2. PTC heater It uses the fan to agitate air to flow through the PTC heating element to force convection, which is the main heat exchange method. 3. Convection heater The upper part of the electric heater shell is the air outlet, and the lower part is the air inlet. After the power is turned on, the air around the electric heating tube is heated up and flows out from the air outlet, while the surrounding cold air enters from the air inlet. Supplement, so...
