The compact liquid heater for the vehicle is characterized in that a shell unit comprises a main shell and a lower cover, and the lower end portion of the peripheral vertical edge of the main shell and the upper end portion of the peripheral vertical edge of the lower cover are connected in a locking and bonding mode; one end of the terminal strip is electrically connected with the thick film heating part of the efficient heat exchange core body unit; the low-voltage connector and the high-voltage connector are fixedly arranged at the low-voltage connector mounting interface part and the high-voltage connector mounting interface part on the main shell respectively; the control unit and the efficient heat exchange core body unit are fixedly mounted on a control unit mounting interface part and an efficient heat exchange core body unit mounting interface part in the top surface of the main shell in an up-down overlapping manner; the water inlet pipe and the water outlet pipe respectively extend out of two through holes in the main shell; pins of the low-voltage connector and the high-voltage connector are respectively connected with pin holes of the low-voltage connector and the high-voltage connector on the PCB; the other end of the terminal strip is inserted into a terminal strip pin hole in the PCB; the two water temperature sensors are respectively inserted into the two water temperature sensor mounting holes in the flat pipe; and the IGBT is clamped and fixed between the main shell and the flat tube. The device is small in size, light in weight and good in sealing performance.

    本发明涉及一种紧凑型车用液体加热器,特点为:外壳单元包括主壳体和下盖,主壳体的外围竖边下端部及下盖的外围竖边上端部锁定粘合连接;端子排一端与高效换热芯体单元的厚膜加热部分电连接;低压、高压接插件分别固装于主壳体上的低压、高压接插件安装接口部处;控制单元及高效换热芯体单元上下叠置固装于主壳体顶面内的控制单元安装接口部和高效换热芯体单元安装接口部;进、出水管分别经主壳体上的两个通孔伸出;低压、高压接插件的插针分别与PCB板上的低压和高压接插件插针孔连接;端子排另一端插入PCB板上的端子排插针孔内;两个水温传感器分别插入扁管上两个水温传感器安装孔内;IGBT夹固于主壳体与扁管之间。本发明体积小、重量轻、密封性好。
