Engine seat with novel cooling jacket

The utility model discloses an engine seat with a novel cooling jacket. The engine seat comprises an underframe for mounting and supporting, a circular outer cylinder mounted on the underframe, a circular middle cylinder in the outer cylinder and a circular inner cylinder in the middle cylinder and flush with two end surfaces of the middle cylinder; two end surfaces of the inner cylinder flush with the middle cylinder are sealed through circular sealing heads to form a first ring cavity, and the space between the outer cylinder and the middle cylinder serves as a second ring cavity; and a water inlet pipe and a water outlet pipe penetrate both the outer cylinder and the middle cylinder and are communicated with the first ring cavity, a spiral baffle plate is arranged in the first ring cavity and is in seal connection with the middle cylinder, the inner cylinder and the circular sealing heads on the two sides of the engine seat, in such a way a spiral passage is formed and connected with the water inlet/outlet pipe. Due to the adoption of the technical scheme provided by the utility model, the motor engine seat and a cooler are combined together to form a more compact structure, and due to the adoption of the spiral passage formed by arranging the spiral baffle plate in the first ring cavity, both the stability of the water side and the comprehensive heat exchange property of the water-cooling engine seat are improved.
