the machined water cooling plate is generally made of metal materials (such as aluminum alloy), has large mass, is not beneficial to light weight and is inconvenient to install and carry;
the machined water cooling plate generally performs single-sided heat exchange, and the other side is directly exposed in the air, so that the heat conduction performance of the metal material is good, and the other side can arbitrarily cause the loss of cold energy, thereby reducing the cooling performance of the power element;
the traditional machine water cooling plate needs a machine water inlet and a water outlet after brazing, part of aluminum scraps can be remained in the water cooling plate in the process, the water cooling plate is excessively large in flow resistance, and the running cost of the water pump is increased.

The utility model aims to overcome the defects, and provides the water-cooling plate made of the composite material, so that the heat exchange performance of the water-cooling plate is improved, the service life of a power element is prolonged, the cost and the gravity of the water-cooling plate are reduced, and the running power consumption of a water pump is reduced.
According to the technical scheme provided by the utility model, the water cooling plate of the composite material comprises:
the device comprises a base plate, wherein a water cooling groove is formed in the middle of the base plate, a water inlet and a water outlet are formed in two ends of the water cooling groove, and a circle of elastic sealing gasket is arranged on the outer ring of the water cooling groove;
the cover plate is fixed on the base plate and used for sealing the water cooling groove, and the cover plate is provided with a mounting hole for fixing the heating element.
As a further improvement of the utility model, the water cooling tank comprises a fin in the middle part and flow channels arranged on two sides of the fin, the flow channels are connected with the water inlet and the water outlet, the plurality of fins are arranged side by side, and cooling water flow channels are reserved between the adjacent fins.
As a further improvement of the utility model, the outer ring of the elastic sealing gasket is also provided with structural sealant.

Detailed Description
The utility model will be further described with reference to examples of embodiments in the accompanying drawings, in which:
as shown, a composite water cooled panel comprising:
the water cooling device comprises a base plate 1, wherein a water cooling groove 3 is formed in the middle of the base plate 1, a water inlet 4 and a water outlet 5 are formed in two ends of the water cooling groove 3, and a circle of elastic sealing gasket 6 is arranged on the outer ring of the water cooling groove 3;
the cover plate 2 is fixed on the base plate 1 and used for sealing the water cooling tank 3, and the cover plate 2 is provided with a mounting hole 10 for fixing a heating element.
The water cooling tank 3 comprises a fin 9 in the middle and flow channels 8 arranged on two sides of the fin 9, the flow channels 8 are connected with the water inlet 4 and the water outlet 5, the plurality of fins 9 are arranged side by side, and cooling water flow channels are reserved between the adjacent fins 9.
The outer ring of the elastic sealing gasket 6 is also provided with structural sealant 7, so that double sealing is realized.
The cover plate 2 is fixed to the base plate 1 by fasteners 11.
The substrate 1 is made of hard plastic.
The cover plate 2 is made of an aluminum material, and is in direct contact with the heating element to form a main heat exchange surface, so that the cover plate is made of a metal material (such as aluminum alloy, copper and the like) with a relatively large heat conductivity coefficient. The base plate and the heating element are not in direct contact, and the main function of the base plate is to reasonably distribute the flow distribution of the cooling liquid through the flow channel, so that the base plate adopts engineering plastics with smaller heat conductivity coefficient and density, thereby not only reducing the heat loss on the base plate, but also reducing the weight of the water cooling plate.
The traditional machine adds the water-cooling board and welds base plate and apron together through brazing earlier, then machine adds water inlet and delivery port of water-cooling board, and in the machine process of adding, part drilling aluminium bits and tapping aluminium bits can fall into the water-cooling board inside, lead to the water-cooling board runner to block up, finally cause the water-cooling board to flow and hinder too big, and water pump running cost improves. The water cooling plate is fastened and sealed through the external fastener and the double sealing structure, and can be conveniently detached and cleaned (such as aluminum scraps and dirt) and replaced and maintained by spare parts in the manufacturing and assembling processes or the using process, so that the heat exchange performance and the service life of the water cooling plate are improved, and the running cost of the water pump is reduced.
The working process of the utility model is as follows:
the heating element transmits heat to the cover plate, and cooling water in the water cooling tank takes away the heat and circulates through the water inlet and the water outlet; the elastic sealing gasket 6 of the structural sealant 7 realizes double sealing and prevents the leakage of cooling water.
