The invention relates to a new energy automobile PTC water heating water tank. The new energy automobile PTC water heating water tank comprises an upper cover plate, a water tank shell and a rubber gasket arranged on the inner surface of the water tank shell, wherein the water tank shell is further provided with a screw hole used for fixing a PTC heating body, a groove and an extension device used for fixing the water tank; the left and right sides of the water tank are separately provided with a water inlet and a water outlet, and the front and back sides of the water tank are provided with insertion ports of a PTC heater in a staggered manner. Through the structure, the water flow direction in the water tank is perpendicular to the placement direction of the PTC heater, so that water resistance is reduced, and heat exchange efficiency is improved; meanwhile, as the PTC heater is in direct contact with a silica gel gasket, sealing performance of a system is guaranteed firstly, and then if a device works in an oscillation environment, a rubber gasket has a buffering effect.
本发明涉及一种新能源汽车PTC水暖加热水箱,包括上盖板、水箱外壳和设置在水箱外壳内表面的橡胶垫片,水箱外壳上还设有用于固定PTC发热体的螺孔、凹槽和用于固定水箱的外延装置;水箱的左右两侧分别设置有进水口和出水口,其前后两侧交错设置有PTC加热器的插入口。通过上述结构,水箱内的水流方向垂直于PTC加热器的放置方向,这样既减小了水阻,又提高了热量交换的效率。同时由于PTC加热器直接与硅胶垫片接触,首先保证了系统的密封性,其次,若装置工作在震荡环境下,橡胶垫片还具有缓冲的作用。
