Direct current ventilation and heat dissipation type electric heater

Abstract

The invention discloses a direct current ventilation and heat dissipation electric heater, which comprises a hollow heat dissipation shell and a heating pipe located in the hollow heat dissipation shell. A plurality of heat dissipation fins uniformly arranged in the horizontal direction are arranged in the hollow heat dissipation shell, and the heat dissipation pipe runs through all heat dissipation The top surface and the bottom surface of the hollow heat dissipation shell are respectively provided with an upper ventilation grille window and a lower ventilation grille window, and the lower ventilation grille window is located directly below the upper ventilation grille window. The present invention adopts the direct current air inlet and outlet mode without changing the flow direction of the wind, and the wind force and wind speed have been significantly improved compared with the existing horizontal air inlet and outlet methods, and the ventilation and heat dissipation effect of the electric heater has been improved. Substantially improved.

Description

technical field [0001] The invention relates to an electric heater, in particular to a direct current ventilation and heat dissipation electric heater. Background technique [0002] An existing electric heater such as figure 1 As shown, the air inlet layer 101 and the air outlet layer 102 are all arranged on the front or back of the electric heater, and the wind enters the inside of the electric heater from the air inlet layer 101 and then comes out from the air outlet layer 102, thereby realizing the effect of ventilation and heat dissipation, but The structural design of this kind of ventilation has the following disadvantages: [0003] 1. Since the air inlet and outlet of the electric heater are horizontal, the wind will accumulate inside the electric heater, and the ventilation and heat dissipation effect is not very ideal; [0004] 2. In order to ensure the ventilation effect, there must be enough space inside the electric heater, so the height of the electric heater ...

[0003] 1. Since the air inlet and outlet of the electric heater are horizontal, the wind will accumulate inside the electric heater, and the ventilation and heat dissipation effect is not very ideal;

[0004] 2. In order to ensure the ventilation effect, there must be enough space inside the electric heater, so the height of the electric heater must be high, because once the height is low and the internal space is small, the
