This fan 5 is pump main body 331 end faces that are connected to this pump 33, and can produce the air-flow in the space of flow through 45 of heating panel 41 ~ 44 and radiating fins.
Shown in Fig. 3,6,7, this flow passage unit 6 is that middle vacant lot is formed in the heating panel 41 ~ 44 and in order to for coolant flow, comprise a plurality ofly, reach a plurality of flow-disturbing sections 66 that lay respectively at diversion section 61,62 upper and lower sides between the upper and lower every symmetry and level first diversion section 61 that is the C font respectively and level second diversion section 62, a plurality of respectively in order to upright first section of linking 63 that is communicated with neighbouring diversion section 61,62 and upright second section of linking 64, the uprightly section of confluxing 65 of down extending from first diversion section 61 of the top.
First to be connected section 63 be up to extend through adjacent two butt projections 412,422 from the outlet side 611 of first diversion section 61 respectively, and the injection end 622 of second adjacent with the top respectively diversion section 61 is communicated with.Second to be connected section 64 be up to extend from the outlet side 621 of second diversion section 62 respectively, and run through adjacent the 3rd butt projection 432 and the first butt projection 412, the second butt projection 422 and the first butt projection 412 respectively, and the second butt projection 422 and the 4th butt projection 442, and the injection end 612 of first adjacent with the top respectively diversion section 61 is communicated with.
The cross section of this section of confluxing 65 is oval in shape, its top is to be communicated with the outlet side 611 of first diversion section 61 that is positioned at the top, and down extend through the projection 443,413,423,433 that confluxes of upper and lower butt, and have one and be formed in the opening the most outwardly 650 of the 3rd plate body 431 bottom surfaces of below.
Flow-disturbing section 66 is to constitute the butt projection 412,422,432,442 that is arranged on reference line 102,103 bearing of trends respectively, and respectively with the diversion section 61,62 of 411,421,431,441 of corresponding two plate bodys be communicated with and depth of section corresponding diversion section 61,62 height all.
Shown in Fig. 4,6,7, during this water-cooled power converter assembling, be pump main body 331 end faces that the heating panel 41 ~ 44 of this heat-sink unit 4, radiating fin 45 and this fan 5 are spliced respectively and be fixed in this pump 33, making, the 3rd plate body 431 windings of below are covered in water pipe 332,333 tops, and make the opening 650 of the section of confluxing 65 that is formed in the 3rd plate body 431 bottom surfaces and the opening 620 of second diversion section 62, reach with these drainage pipe 332 openings respectively and dock, constitute a closed circulation loop that can supply coolant flow and match with these water injection pipe 333 open communication.
When this water-cooled power converter when reducing the temperature of a heater element, be directly the winding board 312 of the heat-conducting plate 31 of this water-cooled seat 3 to be attached to be fixed in this heater element outer surface, start pump main body 331 and fan 5 then.After this pump main body 331 begins action, just can constantly the cooling fluid of this accommodation space 30 will be positioned at, push outward via this drainage pipe 332 and to enter in second diversion section 62 that is connected, the cooling fluid that will be installed in simultaneously in this section of confluxing 65 sucks in this accommodation space 30 via water injection pipe 333.This fan 5 can be constantly, and generation outbound flows through the air-flow of this heat-sink unit 4.
Therefore, the heat that heater element produces can directly conduct to the heat conduction fin 32 in the accommodation space 30 via this heat-conducting plate 31, and the coolant temperature in the accommodation space 30 is risen, when this high temperature coolant is drained in the flow passage unit 6, can be from lower to upper in regular turn via second diversion section 62, second is connected section 64, first diversion section 61, first mode that is connected section 63 and second diversion section 62 flows, and up bending in the process of flowing, constantly heat is conducted in the heating panel 41 ~ 44 of heat-sink unit 4, and conduct to radiating fin 45, heating panel 41 ~ 44 and radiating fin 45 can conduct to heat in the mode of thermal convection arround in the air, and force to loose by the air-flow that fan 5 produces and remove.Can reduce gradually in flow process so discharge the coolant temperature of accommodation space 30, make to flow into coolant temperature in the accommodation space 30 again via the section of confluxing 65, understanding constant proportion, to be positioned at the cooling fluid of accommodation space 30 originally low.Take away by the heat that constantly will conduct to heat conduction fin 32, just can reduce the temperature of heat conduction fin 32 apace, and then can reduce the temperature of heater element fast with the cooling fluid of lower temperature.
What deserves to be mentioned is, when cooling fluid circulates in diversion section 61,62 and flow through the space flow-disturbing section 66 that change is big suddenly, cooling fluid can produce the flow-disturbing stirring action in flow-disturbing section 66, after making that the temperature that flows into the cooling fluid in each flow-disturbing section 66 mixes homogeneous, continue again to flow, thereby can promote the radiating efficiency of unit interval toward next flow-disturbing section 66.
During enforcement, the 3rd and of this heat-sink unit 4 hot plate 43 that scatters, 44 and inessential, can be directly first heating panel 41 of below splices on this pump main body 331 with being positioned at, and the corresponding structural design of adjusting this flow passage unit 6, the injection end 612 of first diversion section 61 that is arranged in this first heating panel 42 is docked with discharge pipe 332 open communication, and this section of confluxing 65 tops are to be communicated with the outlet side 621 of second diversion section 62 of the top, but when implementing, the profile of this heat-sink unit 4, and the quantity of heating panel 41 ~ 44 and assembling mode is neither exceeds with above-mentioned kenel, can allocate according to actual needs.
In addition, this flow passage unit 6 can not be provided with second and be connected section 64, and the first linking section, 63 quantity only are one, and extension is communicated with the outlet side 611 of first diversion section 61 and the injection end 622 of second diversion section 62 from lower to upper, make cooling fluid directly be connected the diversion section 61,62 that section 63 flow to upper and lower interval apace, and compile in this pump main body 331 of inflow in this section of confluxing 65 via first.Flow-disturbing section 66 is also inessential, and the structure of this flow passage unit 6 also can cooperate heat-sink unit 4 external form adjustment.
Take a broad view of above-mentionedly, by the connecting structure design of this water-cooled seat 3, and the design of the distributed architecture of this flow passage unit 6, but can in this water-cooled seat 3 and heat-sink unit 4, constitute the but moving bending loop of liquid recycle stream of a cooling with heat-sink unit 4.The heat that can constantly utilize the lower temperature cooling fluid of injecting this accommodation space 30 will conduct to heat conduction fin 32 is taken away, and is distributed to context in the heating panel 41 ~ 44 of this heat-sink unit 4 and radiating fin 45.The air-flow that this fan 5 produces can quicken diffusing the removing of pressure of the heat of heating panel 41 ~ 44, and significantly promote radiating efficiency, and then can reduce the temperature of heater element fast.So it is very practical really and progressive.
