The invention discloses a heat-insulation cover, and belongs to the technical field of engines. The heat-insulation cover comprises a heat-insulation cover body and a nozzle; the outside of a heat source part is sleeved with the heat-insulation cover body; the area between the heat-insulation cover body and the heat source part is the air area; one end of the air area is an air inlet, and the other end is an air outlet; the nozzle is fixed to the heat-insulation cover body, is used for guiding outside gas into the air area and comprises a gas inlet end and a gas outlet end; the gas outlet endcommunicates with the air area; the gas outlet end faces the air outlet; the nozzle is of a necked structure; and the diameter of the gas outlet end is smaller than that of the gas inlet end. According to the heat-insulation cover, outward transfer of heat produced by the heat source part can be reduced through passive heat insulation; and active directed heat dissipation can be realized, so thathot-dipping working condit
