2K)
δ
1: the surface roughness (μ m) of a side's of formation contact-making surface member
δ
2: the surface roughness (μ m) of the opposing party's of formation contact-making surface member
δ
0: contact equivalent length (=23 μ m)
λ
1: the thermal conductivity (W/mK) of a side's of formation contact-making surface member
λ
2: the thermal conductivity (W/mK) of the opposing party's of formation contact-making surface member
P: contact (MPa)
H a: side's of the softness in the member of formation contact-making surface hardness (Hb)
λ

In addition, use the thermal contact conductance K that obtains by above-mentioned formula 1, find the solution thermal contact resistance Rc according to following formula 2.
Rc=1/ (K * S) ... (formula 2)
Rc: thermal contact resistance (K/W)
S: contact area (m

2Method, reduce a side's of the softness in heat-transfer pipe 110 or the thermofin 120 the method etc. of hardness H.The utility model is conceived to the method for enlarge active surface S.
By increasing the contact area of heat-transfer pipe 110 and thermofin 120, can not reduce thermal contact resistance Rc even do not change thus thermal contact conductance K yet, can improve from heat-transfer pipe 110 to thermofin 120 conductivity of heat.
As mentioned above, in the heat exchanger 1 of present embodiment, not only the wall section 52 between ring portion 5 extensions 51 also contacts with heat-transfer pipe 2, therefore compares with existing heat exchanger, can improve the conductivity of heat from heat-transfer pipe 2 to thermofin 3A.Thus, can improve the heat exchanger effectiveness of heat exchanger 1.In addition, owing to unlike prior art, needing filler, therefore when heat exchanger is discarded, easily carry out Sorting Materials, can not make the deterioration of recirculation property.
