Please refer to Fig. 1 to Fig. 5, the utility model provides a kind of liquid-cooled heat exchange module (being designated hereinafter simply as heat exchange module 1) with even runner.as shown in Figure 1, heat exchange module 1 of the present utility model uses cooling fluid that the electronic heating component 200 on circuit board 100 is dispelled the heat, heat exchange module 1 has for the entrance 111 of cooling fluid turnover and exports 112, entrance 111 is connected with water inlet pipe 310, outlet 112 is connected with outlet pipe 320, the other end of outlet pipe 320 is connected to circulating pump 300, the other end of circulating pump 300 is connected with conduit 330, the other end of conduit 330 is connected to radiating module 400, the other end of radiating module 400 is connected to this water inlet pipe 310, so consist of the loop of a cooling Fluid Circulation of confession.After the electronic heating component 200 on heat exchange module 1 and circuit board 100 carries out heat exchange, the heat that electronic heating component 200 produces can be absorbed by heat exchange module 1, further taken away by the cooling fluid in heat exchange module 1, so the cooling fluid temperature in outlet pipe 320 is higher.Circulating pump 300 is drawn back the cooling fluid of outlet pipe 320, and the cooling fluid that this temperature is higher squeezes in conduit 330, and then is transported in radiating module 400; After cooling fluid enters radiating module 400, in cooling fluid, contained heat can be absorbed by radiating module 400 and temperature decline, the cooling fluid that this temperature descends just leaves radiating module 400 via water inlet pipe 310 and enters heat exchange module 1, prepares this electronic heating component 200 is carried out heat exchange.In this way, repeatedly this electronic heating component 200 is continued to dispel the heat, the temperature of electronic heating component 200 is remained in normal working range.Because cooling fluid commonly used is the water of clear, colorless, so can't indicate in the accompanying drawings, only represent its flow direction with dotted arrow in Fig. 6 to Fig. 9, in this explanation.
Below, structure that will explanation heat exchange module 1 of the present utility model forms, and heat exchange module 1 comprises: housing 10, heat radiation group 20, and baffle 30.
As shown in Figures 2 and 3, housing 10 is made for metal material and is comprised upper cover 11 and base plate 12, base plate 12 directly is attached at electronic heating component 200, upper cover 11 is in order to cover cap and seal base 12, and makes and have between upper cover 11 and base plate 12 for heat radiation group 20, baffle 30 and cooling fluid accommodating space.The upper cover 11 of housing 10 has for the entrance 111 of cooling fluid turnover and exports 112, entrance 111 is arranged near the corner of upper cover 11, as can be seen from Figure 2, entrance 111 is positioned on one of them side surfaces of 11 4 side surfaces of upper cover and contiguous corner, and entrance 111 is flat rectangle to coordinate the profile (this point can remark additionally after a while) of the baffle 30 in housing 10.Outlet 112 be positioned at upper cover 11 top surface the center and protrude out into tube up, be beneficial to outlet pipe 320 and peg graft.In addition, entrance 111 and export 112 setting position and also can change mutually.
Baffle 30 is provided with the first guiding gutter 31 of communicating with entrance 111, with outlet 112 the second guiding gutters 32 that communicate, be communicated with the first guiding gutter 31 and the second guiding gutter 32 storage tank 33 that also cover cap should heat radiation group 20; More particularly, in Fig. 2, near corresponding to upper cover 11 corner on baffle 30 right sides entrance 111 offers the first guiding gutter 31, so the shape of the starting point of the first guiding gutter 31 is flat rectangle corresponding to the shape of the entrance 111 of upper cover 11, the terminal point of the first guiding gutter 31 enlarges and contains the influent side L of whole heat radiation group 20
in, therefore, the first guiding gutter 31 is 33 expansions gradually from entrance 111 towards storage tank.With reference to figure 6, because the starting point of the first guiding gutter 31 is flat rectangle, be conducive to accelerate to inject in the first guiding gutter 31 by the cooling fluid of entrance 111, the first guiding gutter 31 enlarges and its terminal point is contained the influent side L of whole heat radiation group 20 gradually simultaneously
inSo enter the cool stream physical efficiency of the first guiding gutter 31 is diffused rapidly in each fluid channel 211 that reaches heat radiation group 20 from entrance 111, can not be blocked near the starting point of the first guiding gutter 31, can not produce between the terminal point of the first guiding gutter 31 and heat radiation group 20 yet and rebound and produce flow-disturbing.
As can be seen from Figure 6, the profile of the second guiding gutter 32 is the phase antisymmetry with the profile of the first guiding gutter 31, and the starting point of the second guiding gutter 32 contains the water outlet side L of whole heat radiation group 20
out, in order to collect the interior cooling fluid of each fluid channel 211 of all heat radiation groups 20; Then the second guiding gutter 32 draws in gradually and dwindles near another corner that converges in baffle 30, namely the second guiding gutter 32 dwindles towards corner gradually from storage tank 33, and the diminishing design of the second guiding gutter 32 can help to leave the acceleration of the cooling fluid of heat radiation group 20 and collect; Thus, the first guiding gutter 31 is diagonal configuration with this second guiding gutter 32 with respect to housing 10 and heat radiation group 20, tiltedly advance through so the diagonal configuration mode that tiltedly goes out, can make cooling fluid produce maximum flow path in the baffle 30 (also can say the housing 10 of identical floor space) of identical floor space, allow whereby more cooling fluids to flow through baffle 30 and heat radiation group 20, reach better heat exchange effect.
Can find out from Fig. 4, Fig. 5 and Fig. 7, the first guiding gutter 31, storage tank 33 and the second guiding gutter 32 are positioned at the bottom of whole baffle 30 and are in same plane with heat radiation group 20 in fact, cushion afflux groove 34 and be provided with above the second guiding gutter 32, this buffering afflux groove 34 is communicated with the second guiding gutter 32 and outlet 112, the starting point of buffering afflux groove 34 is provided with the breach 341 that communicates with the second guiding gutter 32, and the terminal point of buffering afflux groove 34 is provided with and exports 112 osculums that communicate 342.As shown in Figure 8, the cool stream cognition of leaving the second guiding gutter 32 flows in buffering afflux grooves 34 from breach 341 up, and utilizes this buffering afflux groove 34 as supplying the buffering area on a large scale of gathering; Then, as shown in Figure 9, the cooling fluid in buffering afflux groove 34 leaves whole heat exchange module 1 via osculum 342 from exporting 112.
Refer again to Fig. 6, the characteristics in the geometry design with explanation the first guiding gutter 31 of the present utility model and the second guiding gutter 32.Suppose that housing 10 and baffle 30 are square, heat radiation group 20 is also for square and be positioned at the center of baffle 30, and the first guiding gutter 31 and the second guiding gutter 32 are the phase antisymmetry with respect to the center of heat radiation group 20.As can be seen from Figure 6, a part of cooling fluid at first guiding gutter 31 edges, the leftmost side (minor face) of flowing through will enter the fluid channel 211 of below of heat radiation group 20, then flows out along the second guiding gutter 32 edges, the leftmost side (longest edge); Similarly, then the fluid channel 211 that a part of cooling fluid at first guiding gutter 31 edges, the rightmost side (longest edge) of flowing through will enter heat radiation group 20 the tops flows out along the second guiding gutter 32 edges, the rightmost side (minor face).therefore, due to the whole mutually antisymmetric cause of square and left and right that is shaped as, although the path that above-mentioned two-part cooling fluid is walked is different, but total length is identical, thus, can not only fully use each fluid channel 211 of heat radiation group 20, and the path of walking by this part cooling fluid of each fluid channel 211 is all identical, therefore the utility model can be reached the effect of even runner really, and prevent that cooling fluid is in the crowded and flow-disturbing phenomenon of entrance 111 ends, more fully guide cooling fluid to enter each fluid channel 211, thereby produce best heat exchange effect.
The above is only illustrating of preferred embodiment of the present utility model, is not to limit to protection range of the present utility model, and other any equivalent transformation all should belong to the application's claim scope.
