New energy automobile controller heat dissipation case

The invention provides a new energy automobile controller heat dissipation case which comprises a case body, the case body comprises a bearing plate and a side plate arranged on the periphery of the bearing plate, the front face of the bearing plate is combined with the side plate to form a containing cavity in a surrounding mode, the back face of the bearing plate is sunken to form a cooling flow channel, the front face of the bearing plate is provided with an IGBT installation area, and the IGBT installation area is provided with a heat dissipation groove. The IGBT mounting area sinks to form a water tank, the water tank and the cooling flow channel are communicated with each other, and one side, facing the accommodating cavity, of the water tank is detachably connected with a heat dissipation plate for isolating the water tank from the accommodating cavity. The water tank is arranged in the IGBT mounting area of the bearing plate, and the detachable heat dissipation plate is arranged on the water tank, so
