Abstract
The utility model relates to the field of water cooling plates for heat radiation of power electronic products. Disclosed is a composite water cooling plate based on porous flat tubes. The water cooling plate comprises a plate bottom, a plate cover, a plate core and heat conduction silica gel. The plate core is formed by combination and welding of porous flat tubes to be used as a water channel. The plate core is fixed between the plate bottom and the plate cover. The surface of the plate core is coated by a heat conduction silica gel film or heat conduction silica gel paste. The plate core comprises porous flat tubes, a water chamber bottom plate, a water chamber baffle plate, a water chamber cover plate and water inlet-outlet holes. The water chamber bottom plate and the water chamber cover plate form a water chamber. The water chamber baffle plate divides the water chamber into a plurality of small water chamber units. The porous flat tubes pass through the water chamber bottom plate to communicate the small water chambers with the water inlet-outlet holes to form the water channel. The beneficial effects are that the technical scheme of the water cooling plate allows the water channel and the water cooling plate to be separately machined. The water channel is formed by welding of the porous flat tubes, so that the machining process of the water channel is simpler, small welding area is achieved, large area cover plate welding is prevented, and the water cooling plate is higher in intensity.
