Embodiment 1:
As shown in figures 1-4, a kind of New-type phase change radiator that the utility model embodiment 1 provides, including several heat dissipations are logical
Road 1 and several with the spaced phase variable conduit 2 of heat dissipation channel 1, which is characterized in that phase variable conduit 2 includes two and is spaced apart from each other
Two partitions 21 of partition 21 and sealing form the sealing element 22 of space surrounding；Heat dissipation channel 1 includes being close to what partition 21 was arranged
Radiating fin 11 and the novel strip of paper used for sealing 12 for being set to 11 bottom of radiating fin；Novel strip of paper used for sealing 12 includes integrally formed baseplate part
121, lattice 122 and sealing 123；Baseplate part 121 is set to the bottom of lattice 122；Sealing 123 is set to lattice
122 top；Baseplate part 121, sealing 123 are identical along the length of fluid flow direction in heat dissipation channel 1；With heat dissipation channel
A 1 vertical face is front；The width of facing of lattice 122 is facing width and sealing 123 just less than baseplate part 121
Depending on width；The left side of the bottom surface of sealing 123, the top surface of baseplate part 121 and lattice 122 surrounds to form one and radiate logical
The bottom surface of the identical left groove 124 of fluid flow direction and sealing 123, the top surface of baseplate part 121 and lattice 122 in road 1
Right side surround to form a right groove 125 identical with fluid flow direction in heat dissipation channel 1；It is close to 124 He of left groove
Several flow orifices 211 are offered on the partition 21 of right groove 125；The front/rear end of left groove 124 and right groove 125 passes through welding
Sealing.
After 125 welded seal of left groove 124 and right groove, left groove 124 and right groove 125 be respectively formed one it is closed
Cavity；Due to being provided with flow orifice 211, the right groove 124 of adjacent novel strip of paper used for sealing 12 and adjacent novel strip of paper used for sealing 12 on partition
Left groove constitutes an evaporation cavity being connected to phase variable conduit 2, and evaporation cavity can accommodate liquefied working medium, so as to form having
The phase-change heat sink of several disconnected multiphase variable conduits.When the New-type phase change heat dissipation passed through using the utility model embodiment 1
When device, New-type phase change radiator is fixed on to the top for needing radiator, is needed in the heat transfer to evaporation cavity of radiator, work
The heated vaporization of matter rises along phase variable conduit, and the heat dissipating fluid in heat dissipation channel 1 flows through, and takes away the heat of working medium, working medium liquefaction
Flow into evaporation cavity, by working medium liquefaction, vaporization circulation continuous to needing radiator to radiate.
Since sealing 123, baseplate part 121 and lattice 122 are an integral molding structure, the inside that can be carried is pressed
Power, which is far longer than, is welded together to form evaporation cavity by upper and lower substrates in the prior art, simultaneously because multiphase variable conduit is not
The structure setting of connection, under the same conditions, the internal pressure of the evaporation cavity carrying of the utility model embodiment are also less than existing
There is the pressure of the evaporation cavity carrying of the multiphase variable conduit parallel connection in technology, so the utility model embodiment 1 is relative to existing skill
Evaporation cavity in art can bearing capacity it is stronger, radiating efficiency is also just more preferable；Novel strip of paper used for sealing 12 in the utility model embodiment 1
Not only for the strip of paper used for sealing as heat dissipation channel 1, but also it to be used for the evaporation cavity of phase variable conduit 2, envelope should be welded in the prior art by eliminating
Item, the trouble of welding substrate, improves production efficiency again；The surface that multiple baseplate parts 121 form forms cooling surface can be straight
It connects and is fixed on workpiece to be cooled, eliminate the trouble for also needing welding substrate in the prior art；Phase-change heat in the prior art
When device run-off the straight, phase-change working substance can be stacked into the side of evaporation cavity, and the other side of no working medium or less working medium is caused to be radiated
Effect reduces, and gently then heat dissipation is uneven, heavy then burning apparatus, and the multiphase variable conduit that the utility model embodiment 1 uses is not connected to
Structure, efficiently solve this problem, the flowing space of the working medium in evaporation cavity is smaller, can only gather when tilting
To the side of each evaporation cavity, guarantee there is working medium in each evaporation cavity, when tilting forward and back, since multiphase variable conduit is not connected to,
Under space inside each evaporation cavity is compared, it can also guarantee that working medium will not gather side completely when tilting forward and back；It is existing
Due to being the concatenated radiator of multichannel in technology, once leakage occurs for phase-change working substance can not working medium, and the utility model is real
The not concatenated structure of multiphase variable conduit for applying the use of example 1 will not influence entire radiator even if single-phase variable conduit leaks
Use.
More specifically, baseplate part 121 faces sectional plane in rectangle；The height of baseplate part 121 is 6~18mm.
