Problems solved by technology

[0007] 1. Since the heater is set at the air outlet, the air flow from the acceleration air duct or the fan directly collides with the heater, and there is a great contradiction between the heating effect and the arrangement of the radiator fins of the heater: if the radiator fins are arranged relatively Close, the heat exchange effect is better, but the wind speed at the air outlet is low, and the effect of the air curtain cannot be achieved; on the contrary, if the heat sink is arranged sparsely, the wind speed effect is ideal, but the heat exchange effect is poor;
[0008] 2. Since the heater is set at the air outlet, the resistance of the heater to the airflow makes the distribu

Example Embodiment

[0032] Please refer to figure 1 , Is a schematic diagram of an embodiment of the heating structure disclosed in the present invention.

[0033] Specifically, the heating structure 100 of the present invention includes:

[0034] The housing 110 has an air inlet 111 on one side and an air outlet 112 on the other side;

[0035] The impeller 120 is arranged inside the casing 110, and brings the external airflow of the casing 110 in from the air inlet 111 and discharges from the air outlet 112;

[0036] The heating device 130, including heaters and radiating fins, is arranged in an arc shape along the flow direction of the air drawn by the impeller 120 in the housing 110 and arranged at the air inlet 111 inside the housing 110; the air sucked from the air inlet 111 by the impeller 120 The cold air flow flows through the heating device 130 and exchanges heat with the heat sink of the heating device 130 to absorb heat;

[0037] The airflow acceleration air duct 140 accelerates the airflow flowin

Abstract

The invention discloses an air curtain with multiple heating systems. A heating structure comprises a shell, an air inlet formed in one side face of the shell, impellers arranged in the shell, a motor for driving the impellers to rotate, a control device, an air flow accelerating air flue for accelerating the air flow brought in from the air inlet by the impellers, an air outlet formed in the other side face of the shell and used for discharging the air flow passing through the air flow accelerating air flue out of the shell and heating devices which are arranged in the air inlet in the inner side of the shell in the flowing direction of the air flow sucked in by the impellers in the shell in an arc-shaped manner. According to the air curtain, defects that the heating devices are limited by the size of the air inlet, air feeding is blocked, heating efficiency is not high, and the like are overcome, and good heating efficiency and air curtain discharging efficiency are achieved.
