Heat pipe is a kind of efficient heat transfer element, and heat transfer efficiency and heat flow density are very high.Currently, pipe type micro heat pipe is being set
Be widely used in standby heat management system, but its based on one dimensional heat transfer, there are the limitations of heat transfer area and structure.Phase transformation
Temperature-uniforming plate makes the phase transition process of working fluid become two dimension even Three-dimensional Heat-transfer, and heat source can also directly contact with heat pipe, can be compared with
The temperature of discrete local heat source hot-zone is controlled by force.
Phase transformation temperature-uniforming plate is the plank frame for having hollow cavity, by shell, the capillary structure of enclosure interior and phase
Matter of exchanging work composition, cavity is interior to be filled phase-change working substance and is in negative pressure state.When phase transformation temperature-uniforming plate works, plate absorbs heat, makes to steam
The liquid refrigerant of hair section expands rapidly vaporization, after moving to condensation segment cooling liquid, flows back into evaporator section under capillary action.
There are problems:
As shown in Figure 1, the processing technology of existing phase transformation temperature-uniforming plate 3, main by squeezing flat tube or hollow thin plate, phase is filled
The manufacture of matter of exchanging work post package.Under some application environments phase transformation temperature-uniforming plate 3 needs be arranged vertically with heat source, phase transformation temperature-uniforming plate 3 and
The connection type for contacting the pedestal 4 of heat source is restricted.Typically, groove, the edge of phase transformation temperature-uniforming plate 3 are equipped in pedestal 4
After folding by inserted tooth technique be embedded in 4 groove of pedestal in, wherein after the edge fold of phase transformation temperature-uniforming plate 3 with this consideration of temperature-uniforming plate
It closes.The problem of this inserted tooth connection type, is that 3 bottom of temperature-uniforming plate is assembled to form interference fit by inserted tooth with 4 groove of pedestal,
Magnitude of interference is difficult to control, and assembles if magnitude of interference is larger extremely difficult, and unreliable easy pine is assembled if magnitude of interference is smaller
It is de-, therefore inserted tooth process is poor, production efficiency is low, assembly precision cannot get effective guarantee.In addition, if magnitude of interference compared with
Small, 3 bottom of phase transformation temperature-uniforming plate contacts not close with 4 groove of pedestal, therefore thermal resistance is larger, reduces the heat dissipation of phase transformation temperature-uniforming plate 3
Effect.

Further, the flanging section has one or two layers.
A kind of radiator, including pedestal and above-mentioned temperature-uniforming plate, the temperature-uniforming plate is connected on pedestal by flanging section.
Preferably, mounting groove is offered on the pedestal, the flanging section and mounting groove interference grafting.By flanging section with
When mounting groove is assembled, flanging section can be pressed into mounting groove from top to bottom, it can also be by flanging section from the one of mounting groove
Side insertion, then lateral push are configured, and are laterally inserted into mounting groove because not having flanging section under the certain structures of constructive interference
Condition can be assembled using being longitudinally inserted into from up to down, be conducive to radiator overall construction design, eliminate assembling structure
The limitation interfered and avoided.
Further, the maximum gauge of the flanging section be d, when flanging section is fully pressed its compress with a thickness of
The width of dmin, the mounting groove are W, and W is between dmin~(dmin+0.5mm), and (d-W) is between 0.5~1.5mm.Just
It is inserted into mounting groove in flanging section, and flanging section and mounting groove are combined with suitable magnitude of interference, guarantees that flanging section is pressed on installation
In slot, it is completely embedded reliably, the thermal resistance of temperature-uniforming plate is smaller.
Further, the height of the flanging section is h, and the depth of the mounting groove is H, H≤h.
Further, the mounting groove inner wall offers limiting groove, the board-like knot along the length direction of plank frame
With several retention beads with limiting groove cooperation on the side of structure.Because flanging section and mounting groove are interference fitted, and often exist
There are other structures part, flanging sections laterally to skid off at the both ends of pedestal, and retention bead is inserted into limiting groove, effectively prevent rolling over
Section up and down direction out of mounting groove in side is deviate from, and the structural strength and stability in use of the radiator are improved.
Further, the temperature-uniforming plate is vertical with pedestal.
The utility model has the advantages that the inclined-plane inserted tooth phase transformation temperature-uniforming plate and radiator of the utility model, flanging section and pedestal are processed and are filled
With simple process, production and assembly efficiency are improved；There is angle a, so that flanging section inserted tooth between flanging section and plank frame
When with certain deflection, convenient for assembly, and flanging section connect reliably with mounting groove after assembling, and is contacted closely, and thermal resistance is smaller,
Improve the heat dissipation effect of temperature-uniforming plate；When flanging section and mounting groove are assembled, flanging section can be pressed into peace from top to bottom
In tankage, flanging section can also be inserted into from the side of mounting groove, then lateral push is configured, because of the certain structures of constructive interference
Under do not have the condition that flanging section is laterally inserted into mounting groove, can be assembled using being longitudinally inserted into from up to down, be conducive to
Radiator overall construction design eliminates the limitation that assembling structure is interfered and to be avoided.
