Abstract
The invention relates to a cold plate radiator, including an installation base at a front end for installation of a corresponding device to be radiated. The installation base is internally provided with a vaporization cavity and a cold medium channel, a peripheral jet orifice communicated with the cold medium channel and used for jetting an atomized cold medium towards an edge of the vaporization cavity, and a central jet orifice arranged at a rear side of the vaporization cavity, communicated with the cold medium channel and used for jetting the atomized cold medium from back to front towards a central position of the vaporization cavity. The cold plate radiator provided by the invention solves the problem in the prior art that since the center of the vaporization cavity is far away from a channel exit, a radiating effect of the central position of the vaporization cavity is not good.
Description
Technical field
The present invention relates to the cold plate radiator in field of radiating.
Background technology
The use procedure of common cold plate radiator is, to treat that radiating element is installed in the cold plate base of cold plate radiator, then in cold plate base, coolant media is passed into realize the cooling heat dissipation to cold plate base, can not there is phase-state change in the coolant media in this traditional cold plate radiator, therefore its cooling heat dissipation effect is not fine.
Chinese patent CN101625179A discloses one " vacuum spraying cooler ", this cooler comprises the heat-radiating substrate that thickness of slab extends along the longitudinal direction, the rear plate face of heat-radiating substrate is provided with vaporization chamber and coolant media passage, coolant media passage is a circulating line, coolant media passage is located on the periphery of vaporization chamber, the channel outlet of coolant media passage and feeder connection are arranged in the two lateral walls of vaporization chamber respectively, such vaporization chamber is just gone here and there on coolant media passage, wherein the feeder connection place of coolant media passage is provided with vacuum pump, the channel exit of coolant media passage is provided with sprayer, position opposing with vaporization chamber on the front face of heat-radiating substrate is used for treating that radiating element is installed.During use, vacuum pump provides power for the coolant media in coolant media passage circulates, coolant media sprays vaporific coolant media by sprayer in vaporization chamber, vaporific coolant media contacts rear vaporization and takes away rapidly on heat-radiating substrate heat with vaporization chamber, to realize the thermolysis treating radiating element, the coolant media after vaporization again becomes liquid condition again through liquefaction in cyclic process.Existing this cooler Problems existing is: the front face of heat-radiating substrate only has the corresponding position opposing with vaporization chamber could install and treat radiating element, because coolant media passage is positioned at the equal periphery of vaporization chamber and coolant media and vaporization chamber are in same plane, therefore coolant media passage can take most space of heat-radiating substrate, so just limit the size of vaporization chamber, in order to supply to treat that radiating element is installed, heat-radiating substrate is compulsory very large, in addition because pipe outlet and vaporization chamber are in same plane, therefore the coolant media be atomized can only blow along perpendicular to the edge of fore-and-aft direction by vaporization chamber towards the center of vaporization chamber, the center position of the atomization coolant media distance vaporization chamber sprayed by pipe outlet is far away, cause the radiating effect of vaporization chamber center position not good.
