Thermal energy is conducted in the inside of the phase-change material 302, overcomes phase-change material because heat conductivility itself is poor to easily cause heat distribution uneven
Defect, the mesh section of the heat exchange grid 303C is cellular.As shown in figure 4, pipe wing 4 and belonging to each of one group of heat pipe
Heat pipe transverse tube 3A interfaces, and the longitudinal pitch of adjacent two heat pipe transverse tubes 3A of this group of heat pipe 3 is in region longitudinally in each
L；And in region longitudinally in each, the thickness of the intersection pipe wing of pipe wing 4 and every heat pipe transverse tube 3A is minimum；With pipe wing 4
By the spacing L's that centered on intersection with every heat pipe transverse tube, is extended respectively to upper and lower both sides in the longitudinal region
At 1/2, the thickness of pipe wing gradually increases.Every pipe wing 4 is integrally formed, and there are supply the heat pipe in the intersection
The through-hole H that transverse tube 3A is passed through, centered on H, the spacing L extended respectively to upper and lower both sides with pipe wing 4 1/2 at, pipe wing
Thickness gradually increase, for example, intersection pipe wing thickness be 0.1mm, and 1/2 spacing L at pipe wing thickness be 0.3mm, and
As section thickness increases, pipe wing outside wall surface is in cambered surface shown in Fig. 4.Since the heat conductivility of pipe wing itself is higher than the phase
Become material, therefore, can suitably be thickened in the thickness of the pipe wing far from the heat pipe position pair, to for far from the heat pipe
Phase-change material conduct more heats.In addition, it is to influence heat exchange efficiency that phase-change material condenses into dirty phenomenon in heat pipe outer wall
One big factor；By the non-homogeneous arc surfaced tube wing of above-mentioned progressive thickness, may be implemented it is non-homogeneous expand with heat and contract with cold, closer to heating pipe
The effect of expanding with heat and contract with cold of wing is more apparent, can play the role of stirring to condensation phase change material and be detached from；Under liquid phase state, phase transformation
Material carries out convection current between heat pipe and pipe wing, and the non-uniform shapes of tube wall are conducive to the convection current in intersection so that have tied
Brilliant phase-change material can be removed by convection current, avoid being bonded in heat pipe and fin surface for a long time and influencing to conduct heat.
