Embodiment 1
[0043] See attached Figure 1-5 , 7-9, and 12-14, a round tube-fin heat exchanger includes: a first clamping base 10, a third clamping base 12 corresponding to it is provided below the first clamping base 10, The first clamping base 10 and the third clamping base 12 are connected by two vertically arranged second clamping side plates 11, the second clamping side plates 11 are arranged oppositely with a distance between them, and the second clamping side plates 11 are arranged oppositely with a distance between them. The first heat transfer fin group 31 and the second heat transfer fin group 32 arranged adjacently and spaced apart between the sandwich side plates 11, the first heat transfer fin group 31 and the second heat transfer fin group 32 They are all composed of first fins 30 arranged vertically and at intervals. The first fins 30 of the first heat transfer fin group 31 and the second heat transfer fin group 32 are arranged alternately. The first heat transfer fin group ...
Embodiment 2
[0058] The heat exchange method using a round tube fin heat exchanger is as follows:
[0059] -Convey the heat exchange medium to the second heat transfer pipe body 21, the heat exchange medium flows in the second heat transfer pipe body 21, the heat is transferred to the first fins 31 through the second heat transfer pipe body 21, the air and the first heat transfer pipe body The first fins 31 of the heat fin group 31 and the second heat transfer fin group 32 and the second tube body 21 perform primary and secondary heat exchange;
[0060] -The heat exchange medium is delivered to the first heat transfer pipe body 20, the heat exchange medium flows in the first heat transfer pipe body 20 and flows through the second medium flow hole 42 in the second fin 40, and the heat is transferred to the second With the fins 40 , the air that undergoes primary heat exchange and secondary heat exchange performs tertiary heat exchange with the second fins 40 and the first heat transfer tube...
Embodiment 3
[0063]The further optimization scheme of present embodiment on the basis of embodiment 1 is: see appendix Figure 6 As shown, a round tube fin heat exchanger also includes: a fixed plate body 15, and the fixed plate body 15 is respectively provided with assembly through holes 16 that can be plugged and matched with the first fin 30 and the second fin 40 , the assembly through hole 16 can be coated with heat conduction oil or heat conduction grease in the gap space between the first fin 30 and the second fin 40, and the outside of the fixed plate body 15 can be surrounded by a rubber strip 14, of course the rubber strip 14 can be tear down.
[0064] The first fin 30 and the second fin 40 of the heat exchanger are reinforced in the transverse direction by designing the fixed plate body 15. Although the upper and lower ends of the first fin 30 and the second fin 40 are connected with the first clamping base 10, The three clamping bases 13 are assembled and connected, but it may ...
