Super-conductive conduit road 3, wherein, a Super-conductive conduit road 3 corresponds in the middle part of the region of the Super-conductive conduit road (i.e. described thermal source patch
Close region 5) position be provided with two parallel hot superconduction branch roads, the heat provided with described two parallel hot superconduction branch roads is super
Rodding 3 can suppress the edge of heat sink close to the flat phase transformation of the one side, as shown in figure 1, provided with the two parallel heat
The Super-conductive conduit road 3 of superconduction branch road can also be located at the inner side that the flat phase transformation of the one side suppresses heat sink, that is, be not provided with heat
The Super-conductive conduit road 3 of superconduction branch road suppresses the edge of heat sink close to the flat phase transformation of the one side, as shown in Figure 3.
In another example, Super-conductive conduit road area distribution has the institute that two both ends are connected to form arc circulation line
State Super-conductive conduit road 3, two Super-conductive conduit roads 3 (i.e. described thermal source fit area in the middle part of the region of the Super-conductive conduit road
5) position is connected by a hot superconduction branch road, as shown in Figure 4.
As an example, the Super-conductive conduit direction density in the middle part of the region of the Super-conductive conduit road is also less than the Super-conductive conduit
The Super-conductive conduit direction density of road region other parts.
In one example, Super-conductive conduit road area distribution has two both ends to be connected to form the described of arc circulation line
A Super-conductive conduit is merged on Super-conductive conduit road 3, two Super-conductive conduit roads 3 in the middle part of the region of the Super-conductive conduit road
Road 3, as shown in Figures 5 and 6.
Super-conductive conduit direction density and Super-conductive conduit road region other parts in the middle part of the region of the Super-conductive conduit road
Super-conductive conduit direction density is different, and the big region heat dissipation capacity of Super-conductive conduit direction density is more, the small region radiating of Super-conductive conduit direction density
Measure small so that the pressure imbalance of the heat-transfer working medium of Super-conductive conduit road diverse location, promote the heat-transfer working medium by pressure
High part is to the low partial offset of pressure so that the flat phase transformation of one side suppresses heat sink can be from the thermal source conformable region
Domain 5 is conducted heat upwards, and gravity can be overcome to be conducted heat downwards from the thermal source fit area 5 again.
As an example, the Super-conductive conduit direction density of each several part can also be identical in the region of the Super-conductive conduit road, institute
Two both ends can be distributed with by stating in the region of Super-conductive conduit road is connected to form the Super-conductive conduit road 3 of arc circulation line,
As shown in fig. 7, three Super-conductive conduit roads 3 can also be distributed with, three Super-conductive conduit roads 3 can be connected to form with both ends
Arc circulation line, as shown in figure 8, can also first two both ends of Super-conductive conduit road 3 be connected after, then with another heat
The both ends of superconduction pipeline 3 are connected, as shown in FIG. 9 and 10.
It should be noted that the shape on the Super-conductive conduit road 3 and distribution are only in the region of Super-conductive conduit road described above
Example, it is not limited successively in practical structures.
It should be noted that need to be filled with institute into the Super-conductive conduit road 3 after being formed by the Super-conductive conduit road 3
Heat-transfer working medium is stated, so after the Super-conductive conduit road 3 is formed, can suppress to form filling on heat sink in the flat phase transformation of the one side
Fill mouth 7.The filling exit 7 can be formed on first sheet material 1, can also be formed on second sheet material 2, can be with
Formed on first sheet material 1 and second sheet material 2, in the present embodiment, formed with the filling exit 7 described the simultaneously
Example is used as on two sheet materials 2.The filling exit 7 is after the shape on the Super-conductive conduit road 3 preliminarily forms, the filling exit 7
Sealed by welding manner, and the Super-conductive conduit road 3 near the filling exit is carried out by press seal by techniques such as roll-ins, with
Press seal position 6 is formed, to realize the sealing on the Super-conductive conduit road 3 so that the Super-conductive conduit road 3 does not turn on the external world.Institute
The shape for stating the Super-conductive conduit road 3 at press seal position 6 can be able to be linear according to setting is actually needed, or
Shaped form.

State.
In summary, the present invention provides a kind of flat phase transformation suppression heat sink of one side and mobile terminal device, the one side are put down
The surface that phase transformation suppresses heat sink is plane；The flat phase transformation of one side suppresses to be provided with arc Super-conductive conduit road area in heat sink
Domain, formed with arc circulating thermal superconducting pipeline in the region of the Super-conductive conduit road；The Super-conductive conduit road is closing pipe line,
Heat-transfer working medium is filled with the Super-conductive conduit road；The flat phase transformation of one side suppresses radiating plate surface and is provided with thermal source fit area,
The thermal source fit area is located at the middle part in Super-conductive conduit road region.The flat phase transformation of one side of the present invention suppresses inside heat sink
Formed with Super-conductive conduit road, heat-transfer working medium is filled with Super-conductive conduit road and is closed, with heat conduction rate is fast, samming is good, hot superconduction
The characteristics of thermal resistance is small between pipeline and sheet material；It is one side flat structure that phase transformation, which suppresses heat transfer plate, is easy to the flat phase transformation of the one side to suppress
Heat sink is fixedly connected with miscellaneous part；Super-conductive conduit road region and Super-conductive conduit road are disposed as arc, can be fully sharp
With the space in mobile terminal device；Super-conductive conduit road is arc circulating thermal superconducting pipeline, and thermal source fit area is super positioned at heat
The middle part in rodding region, thermal source fit area fitting thermal source caused by heat can self-heat power conduct heat upwards, can also
Self-heat power conducts heat downwards；Super-conductive conduit direction density and Super-conductive conduit road region other parts in the middle part of the region of Super-conductive conduit road
Super-conductive conduit direction density it is different, the big region heat dissipation capacity of Super-conductive conduit direction density is more, and the small region of Super-conductive conduit direction density dissipates
Heat is small so that the pressure imbalance of the heat-transfer working medium of Super-conductive conduit road diverse location, promotes heat-transfer working medium by the high portion of pressure
Divide to the low partial offset of pressure so that the flat phase transformation of one side, which suppresses heat sink, to conduct heat upwards, can overcome weight again
Power is conducted heat downwards；The flat phase transformation of one side of the present invention suppresses heat sink gross thickness and is less than 1mm, and internal Super-conductive conduit road size is small, nothing
Capillary structure, manufacture craft is simple, is advantageous to scale production in enormous quantities.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
