Abstract
The utility model discloses a water-cooled heat sink for enhancing heat dissipation. The water-cooled heat sink for enhancing heat dissipation is characterized by comprising a base board and a cover board, the base board is provided with protruding spiral blocking ribs comprising large ribs and small ribs, the cover board is provided with large grooves and small grooves into which the large ribs and the small ribs can be embedded, small convex strips are arranged between each large groove and the corresponding small groove of the cover board, the height of the small convex strips is 0.25mm, and the distance between every two adjacent small convex strips is 2.8mm. The water-cooled heat sink for enhancing heat dissipation has the advantages that the turbulence function of water is increased through the protruding convex strips, on the basis of not affecting water pressure largely, the turbulence effect can be played to the maximum extent, the heat dissipation performance of the heat sink is enhanced, the structure is simple and the heat dissipation effect is good.
Description
Technical field
The utility model relates to a kind of radiator, be specifically related to a kind of water-filled radiator that strengthens heat radiation.
Background technology
Existing water-filled radiator, upper and lower two cover plates weld and substrate junction integrator by agitating friction, and the inner screw type cavity forming becomes the runner of water, and heater element contacts with spreader surface, heat is passed to radiator, afterwards water in runner again the heat radiator take away.In existing water-filled radiator, runner is conventional runner, be that cross section of fluid channel is a rectangle, water can only be by four walls and the radiator generation heat convection of contact, heat exchange area is limited, and due to four wall comparison rule, water mobile more stable, heat transfer effect is general, and the heat dispersion of final existing water-filled radiator does not reach client's heat radiation requirement.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of water-filled radiator that strengthens heat radiation.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of water-filled radiator that strengthens heat radiation, it is characterized in that: comprise substrate and cover plate, described substrate is provided with protruding spirality barrier rib, described barrier rib comprises large muscle and little muscle, described cover plate is provided with large muscle, the embeddable big groove of little muscle and little groove, between the big groove of described cover plate and little groove, be provided with little raised line, the height of described little raised line is 0.25mm, and the spacing of adjacent two little raised lines is 2.8mm.
Described little raised line is perpendicular to big groove and little groove.
The length of described little raised line is 3mm, and width is 0.25mm.
The beneficial effects of the utility model: the utility model utilizes the raised line of projection to increase the flow-disturbing effect of water, can bring into play flow-disturbing effect on to the little basis of water pressure drop affects to greatest extent, strengthen the heat dispersion of radiator; Simple in structure, good heat dissipation effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail.
Fig. 1 is decomposition texture schematic diagram of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
The specific embodiment
