Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein
Same or similar label represents same or similar element or has the function of same or like element from beginning to end.Lead to below
Cross the embodiment being described with reference to the drawings to be exemplary, be only used for explaining the utility model, and cannot be construed to this practicality
New limitation.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein（Including technology art
Language and scientific terminology）With the identical meaning of the general understanding with the those of ordinary skill in the utility model fields.Also
It should be understood that those terms such as defined in the general dictionary should be understood that with the context of the prior art
The consistent meaning of meaning, and unless defined as here, will not be explained with the implication of idealization or overly formal.
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of cold plate heat exchanger to liquidate based on the temperature difference, includes
Heat-conducting substrate 2, flows through or places the manufacturing process such as heat dissipation heat source 5, substrate side is by extruding, cutting, die casting, formed and cut thereon
Face is large semi-circular（Arc chord angle is not less than 180 degree）Open channel or passage of remaining silent.Passage is embedded in heat-transfer pipe 1, heat-transfer pipe 1
Interference fit is formed between opening or passage of remaining silent, wherein, arrangement and its quantity, channel sized, the length foundation of heat-transfer pipe
The bulk of heat source 5 that radiates and size determine.1 two-way of heat-transfer pipe arranges that working medium inversely goes with each other all the time, two-way heat-transfer pipe 1 according to
Minor tick is arranged symmetrically, liquidate due to the temperature rise of diabatic process intraductal working medium and caused by the substrate temperature difference, smooth out cold plate temperature field.It is cold
After plate intraductal heat transfer working medium 6 is entered in heat-transfer pipe 1 heat for absorbing heat dissipation heat source 5 by double feed inlet collector 3, temperature rise is produced, by
Double outlet headers 4 flow out cold plate, are cooled down after outflow cold plate by external source heat exchange and return to inlet condition, then sequentially enter biography
Heat pipe 1 forms a circulation, and so on endlessly.
In the utility model, the heat-exchanging tube bundle can be gas, the single-phase temperature of liquid for the heat-transfer working medium described in multithread
Difference heat exchange.The heat-transfer working medium can be liquid phase-change heat exchange.It can be multipaths that the heat-transfer pipe, which is,.The heat transfer
Pipe and substrate are metal or non-metallic material.
Temperature liquidate intraductal heat transfer working medium 6 heat transfer process it is as follows：6 symmetrical double route double feed inlet of cold plate intraductal heat transfer working medium
Collector 3 enters heat-transfer pipe, and the heat conduction or convection current by heat convection in pipe, the heat conduction of heat-transfer pipe and substrate, substrate and heat source are complete
Into diabatic process, due to cold plate micro-element structure and the symmetry of heat source, the two-way temperature of a certain infinitesimal of reverse flow intraductal working medium
（Rise）Difference is asymmetric in addition to midpoint, it is assumed that midpoint infinitesimal two-way is temperature difference t, and mean temperature difference is also Δ t, arbitrary point
Two-way temperature difference t+d, Δ t-d then mean temperature difference（（Δt+d）+（Δt-d））/ 2, also it is Δ t, the so asymmetric temperature difference is right
Punching, is generalized to cold plate universe, it is believed that whole cold plate temperature field is smoothed out by liquidating.
