Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of to exist in the prior art, there is provided a kind of high new of heat dispersion Type water-cooling type radiator.
To achieve these goals, the utility model uses following technical scheme:
A kind of novel water-cooled radiator, including main body and cover plate, described main body are provided with some water stream channel loops, The distribution in the water stream channel loop uses parallel-connection structure, and the one side of the main body is provided with water stream channel entrance and current are logical Road is exported, described water stream channel loop respectively with water stream channel entrance and water stream channel outlet, described main body and lid Solder plate is provided between plate, described cover plate is provided with some heating blocks.
The utility model uses the work being designed to for multiple heating blocks in multiple water stream channel loops, so that significantly Degree reduces temperature and thermal resistance, while using solder plate come the connection between realization body and cover plate so that between main body and cover plate Connection it is even closer so that on cover plate generate heat block produce heat sufficiently can be inhaled by water stream channel loop in main body Receive, so as to effectively improve heat dispersion.
Preferably, described cover plate is integrally welded with main body using vacuum brazing technique by solder plate.Using true Empty soldering processes come welded cover plate, solder plate and main body, enable to the heat-conductive characteristic between cover plate and main body more prominent, The heat of heating block on cover plate is conducive to conduct, so as to improve heat dispersion indirectly.
Preferably, being provided with two guiding gutters in described main body, described water stream channel loop is placed in two guiding gutters Between and connect with guiding gutter, two of which guiding gutter respectively with water stream channel entrance and water stream channel outlet, it is described Water stream channel entrance and water stream channel outlet include pod apertures and water nozzle, and described water nozzle is arranged in pod apertures, described Pod apertures are connected with guiding gutter.By the design of said structure, it is easily installed and maintenance.
Preferably, being provided with some S-shaped fin notches in described water stream channel loop, described S-shaped fin notches are in Symmetrical point of row are arranged in water stream channel loop.It has been designed to using the water stream channel loop of S-shaped fin notches structure Effect enhancing area of dissipation and forced refluence effect, so as to thermal resistance is greatly lowered, meet high power device cooling requirements;Meanwhile, The inside in water stream channel loop is provided with some S-shaped fin notches point row arrangement and can effectively support pressure-bearing solder plate and cover plate, and Bonding area is increased, reliability is high, improve the security of overall assembling.
Preferably, the shape of cross section of the S-shaped fin notches is circular or polygon.
Preferably, the heating block on the cover plate is corresponding with the water stream channel loop upper-lower position in main body.It is many Individual heating block and multiple water stream channel loops up and down to should be able to for the work of high performance components in multiple heating blocks, So as to temperature rise and thermal resistance is greatly lowered.
The beneficial effects of the utility model are:Improve heat dispersion;Effectively strengthen area of dissipation and forced refluence effect, greatly Amplitude reduction thermal resistance meets high power device cooling requirements;Effectively support pressure-bearing, and increasing bonding area, reliability is high, improves The security of overall assembling;Temperature rise and thermal resistance can be greatly lowered for multiple heating block work.
