In air cooling, electronic chip radiator adopts metal material moulding, and by contacting with electronic chip heat conduction is carried out, Then using the cooling of the forced air convections such as fan, fan power consumption is not only increased, and noise is improved, and affects great-power electronic The use environment of device.Cooled down using air, it is desirable to which ambient temperature is reduced to 25 DEG C or so and just can guarantee that chip surface temperature exists In optimum range, air-conditioning power consumption is big, and energy-saving effect is poor.Placement environmental requirement additionally, due to electronic device is dustless, using fan Cooling is forced to require air cleanliness higher.

Liquid working substance is time of contact short with chip in liquid spraying cooling, and heat absorption is few, and liquid working substance service efficiency is low.

For disadvantage mentioned above, it is badly in need of a kind of radiator of the use of invention in liquid spraying cooling to extend liquid working substance With the time of contact of chip, fully radiating, improve chip and enter the fuel-displaced temperature difference, so as to improve the service efficiency of liquid working substance.

Utility model content

The purpose of this utility model is to provide a kind of liquid submersion chip radiator, in solving existing liquid spraying cooling Liquid working substance is time of contact short with chip, and heat absorption is few, the low problem of liquid working substance service efficiency.

To solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：

A kind of liquid submersion chip radiator of this utility model, including the housing being attached to above chip；The housing Oil trap of the inside with upper end open, the housing bottom is provided with multiple circulation grooves, the circulation groove and the oil trap Connected by opening；The open lower side of the circulation groove, under shed is contacted with chip；The housing the week side of boss offers multiple overflowing Chute, the inner port of the overflow launder and the oil sump, external port leads to the hull outside.

Further, the profile of the oil trap be shaped as it is bowl-shape.

Further, the profile of the oil trap is shaped as cylinder, square cylinder or polygon cylinder.

Further, the opening is vertical through hole, and upper end connects with the bottom of the oil trap, lower end with it is described Circulation groove is connected.

Further, multiple circulation grooves are circumferentially arranged, and multiple circulation grooves have a termination to converge to centre Connect with the opening.

Further, multiple overflow launder levels are circumferentially arranged.

Further, the overflow launder is located at the side wall middle part of the housing.

Further, the outline of the housing is shaped as cylindric, square cylinder or polygon cylinder.

Compared with prior art, Advantageous Effects of the present utility model are as follows：

This utility model compared with liquid working substance to be directly sprayed to the type of cooling of chip surface, by oil trap by liquid Body working medium is converged, and is finally contacted with chip via circulation groove, on the one hand the relative time of contact for extending liquid working substance and chip, Be conducive to chip surface samming, fully radiating, improve chip and enter the fuel-displaced temperature difference, so as to improve the service efficiency of liquid working substance； Another aspect liquid working substance stores a period of time in oil trap, can carry out part preheating, it is to avoid temperature drastically changes to core The impact of piece.

Specific embodiment

As Figure 1-3, a kind of one of which specific embodiment of liquid submersion chip radiator, including being attached to core The housing 1 of the top of piece 6, being shaped as the outline of housing is cylindric, square cylinder or polygon cylinder, in this specific embodiment Being shaped as the outline of housing is cylindric, and the oil trap 2 of upper end open, the profile of oil trap 2 are offered inside the housing 1 Shape can be bowl-shape, cylinder, square cylinder or polygon cylinder, the oil trap 2 opened up in housing 1 in this specific embodiment It is shaped as bowl-shape, for collecting the liquid working substance of top drippage, the upper end open of bowl-shape oil trap 2 is big, and smooth-sided is transitted to Bottom.Oil-collecting trench bottom offers vertical opening 4, and the lower end of opening 4 is communicated with 12 circulation grooves, 5,12 circulations Circumferentially shape dissipates the level of groove 5 to surrounding, and the open lower side of the circulation groove 5, under shed is contacted with chip 6, in oil trap 2 Cooling working medium circulates in groove 5 via opening 4, so as to contact with chip 6, by this kind of heat spreader structures liquid working substance is made With the directly contact of chip 6 and time enough can be kept, liquid working substance fully exchanges heat with chip 6, improves radiator turnover The temperature difference of liquid working substance, so as to improve the utilization ratio of liquid working substance.

In addition to above-mentioned technical characteristic, the side wall centre position the week side of boss of the housing 1 offers multiple overflow launders 3, overflow launder 3 By the side wall ring face of housing 1, uniformly arrangement is full, and the inner port of each overflow launder 3 is connected with the oil trap 2, and external port leads to institute The outside of housing 1 is stated, oil trap 2 is connected with the outside of housing 1, make the internal liquid working medium of oil trap 2 converge to the height of overflow launder 3 When, liquid working substance flows out from overflow launder 3.

The radiator of liquid submersion chip 6 of the present utility model can adopt the material of light weight, low cost to make, and existing Some metal alloy heat-sink devices are compared, and cost performance is high；The use of server internal fan is avoided simultaneously, power consumption is reduced, and reduction is made an uproar Sound.

When chip 6 is started working, outside spray system is opened, and the liquid working substance of upper end spray passes through bowl-shape oil trap 2 The bottom of housing 1 is converged to so as to liquid level is constantly raised；When liquid level is increased to 3 height of overflow launder, liquid working substance flows from overflow launder 3 Out keep liquid level；Simultaneously liquid working substance enters liquid flow groove 5 by the liquid flow through hole 4 of bottom, and by liquid The bottom opening of body circulation groove 5, with the following directly contact of chip 6, the heat that heater element is produced is taken to and is dissipated at a distance, then The liquid working substance of cooling is sprayed again on radiator, said process is circulated.

Embodiment described above is only that optimal way of the present utility model is described, not to of the present utility model Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are new to this practicality Various modifications and improvement that the technical scheme of type is made, all should fall into the protection domain of this utility model claims determination It is interior.
