The invention discloses a hydroelectric heater. The hydroelectric heater comprises: a water jacket assembly, wherein an inner cavity of the water jacket assembly is a water chamber, a water inlet and a water outlet are led out of the water chamber, a circulating water pump is arranged on the water inlet, and a water temperature control switch is arranged on the water outlet; an end cover which is fixed at one end of the water jacket assembly, wherein an inner cavity of the end cover is a high-voltage electrical chamber separated from the water chamber, a wiring terminal disc and a contact relay are arranged in the high-voltage electrical chamber, and the circulating water pump and the water temperature control switch are electrically connected in a low-voltage loop of the contact relay; and electric heating pipes, wherein the pipe bodies of the plurality of electric heating pipes are distributed in the water chamber, the head ends of the electric heating pipes are fixed on the end cover, each head end lead is connected to the wiring terminal disc, each electric heating pipe is electrically connected in a high-voltage loop of the contact relay in series and/or in parallel, and the high-voltage loop is controlled to be closed and opened by the low-voltage loop. The hydroelectric heater improves the environmental protection property, is low in noise, high in heat efficiency and low in heat loss, does not need to start heating frequently, and reduces the influence on the endurance of an electric vehicle.
本发明公开了一种水电加热器,包括:水套总成,其内腔为水室,水室中引出有进水口和出水口,进水口上设置有循环水泵,出水口上设置有水温温控开关;端盖,固定于水套总成的一端,端盖的内腔为与水室隔开的高压电气室,高压电气室中设置有接线端子盘和接触式继电器,循环水泵与水温温控开关电连接于接触式继电器的低压回路中;电加热管,若干个电加热管的管体分布于水室中,头端固定于端盖上,且各头端引线连接于接线端子盘,各个电加热管串联和/或并联地电连接于接触式继电器的高压回路中,高压回路由低压回路控制闭合与断开。上述水电加热器提高了环保性,低噪音,热效率高,热散失低,无需频繁启动加热,减小了对电车续航影响。
