The invention discloses a water-cooling type measurement rake which is capable of achieving measurement of pressure and temperature of wake flow under the high-temperature condition of the wake flow of an engine. According to the technical scheme, a rake arm is fixed on a ground support through a rake base, a water inlet is formed in the bottom of the rake base, the water inlet is connected with a spray header with nozzles in lateral walls, the spray header stretches into a rake body frame of the rake arm, the outer surface of the rake body frame is coated with skin, the surface of the skin is coated with high-temperature coating, a temperature measure point protruding out of the skin and a total pressure measure point attached to the skin are arranged on the windward side of the rake arm, a static pressure measure point is arranged on a lateral side, close to the total pressure measure point, of the rake arm, the static pressure measure point is attached to the skin, and a water outlet is formed in the leewa
