The invention discloses an electric heater, a circulation cavity assembly thereof and an electric vehicle, the circulation cavity assembly (200) comprises a flow channel part, two main flow channels and a fin pressing plate (230), the flow channel part comprises a plurality of fluid channels which are horizontally arranged, the two main flow channels are arranged above the two ends of the flow channel part respectively, the fin pressing plate (230) is arranged above the flow channel part, and the two main flow channels are arranged in the flow channel part. The edges of the two sides of the fin pressing plate (230) extend into the main flow channel, so that fluid is allowed to bypass the edges of the two sides of the fin pressing plate (230) to flow between the main flow channel and the flow channel part. In the circulation cavity assembly, fluid bypasses the edge of the fin pressing plate to flow between the main flow channel and the flow channel part under the action of the fin pressing plate, so that the fluid can flow through the areas at the two ends of the flow channel part, the heat exchange area is increased, and the heat exchange efficiency is improved.
本申请公开了电加热器及其循环腔总成和电动车辆,所述循环腔总成(200)包括流道部、两个主流道、翅片压板(230),所述流道部包括水平排布的多个流体通道,两个所述主流道分别设置在所述流道部的两端上方,所述翅片压板(230)设置在所述流道部上方,所述翅片压板(230)的两侧边缘伸入所述主流道内,以允许流体绕过所述翅片压板(230)的两侧边缘在所述主流道与所述流道部之间流动。本申请的循环腔总成中,流体在翅片压板的作用下,绕过翅片压板的边缘在主流道与流道部之间流动,使流体能够流过流道部的两端区域,增加了换热面积,从而提高了换热效率。
