The invention relates to an electric heating device (2) comprising an electronics housing (9) with a partition wall (8) separating a connection chamber (6) from a heating chamber (4) for emitting heat to a medium to be heated, and a fluid housing (38) delimiting the heating chamber (4), in which at least one PTC heating device (14) is formed, a control device (20) having at least one circuit breaker (22) is formed in the connection chamber (6), and is characterized in that the circuit breaker (22) bears against a channel base (32) which is formed outside the heating chamber (4) by a partition wall (8), which channel base forms a channel (34) together with a channel top (36), a medium can flow through the channel. This eliminates the need for a complex heat sink or the like, and waste heat from the circuit breaker (22) may be used to heat the medium.

    本发明涉及一种电加热装置(2),其包括电子设备壳体(9)和流体壳体(38),电子设备壳体带有分隔壁(8),分隔壁将连接室(6)与用于向待加热介质发出热的加热室(4)分隔开,流体壳体界定加热室(4),其中形成至少一个PTC加热装置(14),其以导热的方式连接到加热室(4)并且在连接室(6)中被电连接,其中在连接室(6)中形成具有至少一个断路器(22)的控制装置(20),并且其特征在于,断路器(22)抵靠由分隔壁(8)形成在加热室(4)外部的通道基部(32),通道基部与通道顶部(36)一起形成通道(34),介质能够流动通过所述通道。这消除了对复杂散热器等的需要,并且来自断路器(22)的废热可以被用于加热介质。
