Embodiment 30:

Another embodiment of the invention proposes a kind of 104 pipe heat exchanger of fin, including any of the above-described embodiment Fins set 10, further include the heat exchanger tube being sheathed in the pore of fins set 10.It is multiple when the quantity of pore group 102 is multiple Pore group 102 is along perpendicular to fluid flow direction array；Every two adjacent pore group 102 along perpendicular to fluid flow direction it Between distance P_tFor 12~25mm, the range of the internal diameter D of heat exchanger tube is 5~9mm.

When 104 pipe heat exchanger of fin is exchanged heat, heat carrier flows in heat exchanger tube, and fluid flows between fin 104 It is dynamic.Heat carrier transfers heat in heat exchanger tube, and heat exchanger tube transfers heat on fin 104, subsequent fin 104 and pore with Fluid between fin 104 carries out fluid interchange.When fluid carries out fluid interchange between fin 104, the first 1042 energy of concave-convex ripple Enough reduce the characteristic dimension of fluid interchange between fluid and fin 104, thus enhanced heat exchange, the second concave-convex ripple 1056 to flow Body constantly changes the direction of motion under the action of fin 104 during the motion, and fluid is on the one hand made constantly to destroy and develop New boundary layer, so that enhanced heat exchange, improves the coefficient of heat transfer on 104 surface of fin；Another aspect fluid constantly impacts fin 104 Surface, a possibility that 104 surface scale of fin can be reduced, so that the heat exchange property of fins set 10 is more stable.First is recessed The wave amplitude of convex ripple 1042 and the second concave-convex ripple 1056 needs to be set as optimum value, and two all in accordance with the design of fins set 10 The wave amplitude of person is different so that the first concave-convex ripple 1042 and the second concave-convex ripple 1056 can maximumlly enhanced heat exchange, from And the heat exchange property of fins set 10 is enable to be promoted to the maximum extent.First concave-convex ripple 1042 and the second concave-convex ripple simultaneously 1056 can increase the heat exchange area of fin 104, to improve the heat exchange property of fins set 10.Two adjacent simultaneously fins 104 Between spacing F_pIdentical, so that the fluid flowing between fin 104 is steady, the heat exchange of 104 various pieces of fin is uniform.Simultaneously Bending side structure is set in pore group 102 by actual condition, exchanges heat the heat exchange of weak side to strengthen pore, improves fin The heat exchange property of 104 pipe heat exchangers.

When the quantity of pore group 102 is multiple, multiple pore groups 102 are along perpendicular to fluid flow direction array, often at this time Two adjacent pore groups 102 are along perpendicular to the distance between fluid flow direction P_tFor 12~25mm, when every two adjacent Pore group 102 is along perpendicular to the distance between fluid flow direction P_tWhen for 12mm, the spacing of pore group 102 is smaller at this time, Under identical fluid flow rate, fluid can more fully be disturbed, so that the heat exchange of fluid is more abundant in heat exchanger, simultaneously 102 spacing of pore group is smaller, and the quantity of pore is also more in the fin 104 of same size, in order to enable in pipe heat pipe Heat carrier be able to carry out sufficient heat exchange, the flow velocity of the heat carrier in pipe heat pipe should be reduced at this time；It is every two adjacent Pore group 102 is along perpendicular to the distance between fluid flow direction P_tWhen for 25mm, the spacing of pore group 102 is larger at this time, fits For the higher situation of heat carrier flow velocity in heat exchanger tube, according to the flow velocity and actual condition every two phase of fluid in practical application Adjacent pore group 102 is along perpendicular to the distance between fluid flow direction P_tSelect any number within the scope of 12~25mm.

The range of the internal diameter D of heat exchanger tube is 5~9mm, and when the internal diameter D of heat exchanger tube is 5mm, pipe heat pipe internal diameter D is smaller at this time, The small volume of the heat carrier flowed through in the identical flow velocity lower unit time, therefore in the case where guaranteeing heat transfer effect, Ke Yiti The flow velocity of heat carrier in high heat exchanger tube is suitable for the higher situation of heat carrier flow velocity；When the internal diameter D of heat exchanger tube is 9mm, manage at this time Heat pipe internal diameter D is larger, and the volume of the heat carrier flowed through in the identical flow velocity lower unit time is more, therefore, in order to ensure that heat transfer effect, The flow velocity for needing to reduce heat carrier in heat exchanger tube flows slower situation suitable for heat carrier, according to stream in practical application The flow velocity of body and the internal diameter D of actual condition heat exchanger tube select any number in 5~9mm.

The technical scheme of the present invention has been explained in detail above with reference to the attached drawings, and the invention proposes a kind of fins set and finned tubes Formula heat exchanger, reduces heat exchange characteristic dimension using the first concave-convex ripple, so that fluid is constantly destroyed and is sent out using the second concave-convex ripple The boundary layer of Zhan Xin, the first concave-convex ripple and the second concave-convex ripple increase the heat exchange area of fins set, to improve fin The heat exchange property of group.
