These the 1st cut out rising portions 4a～4c and the 2nd and cut out rising portions 4d～4f and be configured to tilt with respect to the flow direction of air-flow, so that near the air-flows the heat-transfer pipe 3 are directed to the flow direction rear side of the air-flow of heat-transfer pipe 3.More specifically, cut out rising portions 4a～4c about the 1st, the 1st cut out rising portions 4a～4c with respect to the angle of attack α 1 of the flow direction of air-flow on the occasion of, the 1st cuts out rising portions 4a～4c configuration side by side as the crow flies on straight line M1.And, cut out rising portions 4d～4f about the 2nd, the 2nd cut out rising portions 4d～4f with respect to the angle of attack α 2 of the flow direction of air-flow on the occasion of, the 2nd cuts out rising portions 4d～4f configuration side by side as the crow flies on straight line M2.Here, angle of attack α 1, α 2 cut out under rising portions 4a～4f inclination situation as follows on the occasion of: compare with the flow direction rear end 6a～6f of the air-flow that respectively cuts out rising portions 4a～4f, the flow direction front end 5a～5f that respectively cuts out the air-flow of rising portions 4a～4f is positioned at from heat-transfer pipe 3 side far away.
And in the present embodiment, towards the flow direction downstream of air-flow, the height from thermofin surface 2b that respectively cuts out rising portions 4a～4f increases gradually.More specifically, cut out rising portions 4a about the 1st, the height height of rear end 6a from the aspect ratio front end 5a of thermofin surface 2b from thermofin surface 2b, cut out rising portions 4b about the 1st, the height height of rear end 6b from the aspect ratio front end 5b of thermofin surface 2b from thermofin surface 2b, cut out rising portions 4c about the 1st, the height height of rear end 6c from the aspect ratio front end 5c of thermofin surface 2b from thermofin surface 2b, cut out rising portions 4d about the 2nd, the height height of rear end 6d from the aspect ratio front end 5d of thermofin surface 2b from thermofin surface 2b, cut out rising portions 4e about the 2nd, the height height of rear end 6e from the aspect ratio front end 5e of thermofin surface 2b from thermofin surface 2b, cut out rising portions 4f about the 2nd, the height height of rear end 6f from the aspect ratio front end 5f of thermofin surface 2b from thermofin surface 2b.And, if the mean value (i.e. (a+b)/2) that the height from thermofin surface 2b that establishing the height from thermofin surface 2b of the flow direction front end of the air-flow that respectively cuts out rising portions 4a～4f is front end height a, establish the flow direction rear end of air-flow is rear end height b, establish front end height a and rear end height b is average height H (with reference to Fig. 5), then (promptly { (a+b)/2}/FP) be set at except that the value that this average height H obtains greater than 0.3 and less than 0.6 with spacing of fin FP.In fin tube heat exchanger, a plurality of rising portions that cut out of arranging towards the downstream from the flow direction upstream side of air-flow are configured to tilt with respect to the flow direction of air-flow, so that near the air-flow the heat-transfer pipe is directed to the flow direction rear side of the air-flow of heat-transfer pipe, in this fin tube heat exchanger, the present application people cuts out the heat transfer property of rising portions with the form evaluation that flowing resistance add is considered and finds aforesaid average height H among rising portions 4a～4f and the relation of spacing of fin FP of respectively cutting out.Particularly, the present application people finds: be configured to tilt with respect to the flow direction of air-flow at a plurality of rising portions that cut out of arranging towards the downstream from the flow direction upstream side of air-flow, so that near the air-flow the heat-transfer pipe is directed in the fin tube heat exchanger of flow direction rear side of air-flow of heat-transfer pipe, when cutting out the heat transfer property of rising portions with the form evaluation that flowing resistance is added consideration, remove the increment rate Δ Pa that has added the flowing resistance when cutting out rising portions with the increment rate Δ ha that has added the heet transfer rate when cutting out rising portions the value (Δ Pa/ Δ ha) that obtains and above-mentioned (a+b)/2}/FP between, have relation shown in Figure 6, according to this relation derived that the promotion rate of the heat transfer property under the per unit flowing resistance improves (a+b)/scope of 2}/FP is for greater than 0.3 and less than 0.6 scope.
And, in the fin tube heat exchanger 1 of present embodiment, be configured to tilt at each with respect to the flow direction of air-flow, so that near the air-flows the heat-transfer pipe 3 are directed to a plurality of rising portions 4a～4f that cut out of flow direction rear side of the air-flow of heat-transfer pipe 3, is prerequisite with rear end height b than front end height a height, use the relation of above-mentioned average height H and spacing of fin FP, so, about the flow direction upstream side of air-flow cut out rising portions (for example be configured in air-flow flow direction upstream side cut out rising portions 4a, 4d), can not make the height that cuts out rising portions of the flow direction upstream side of air-flow spend low from thermofin surface 2b, thus, increased the effect that produces longitudinal turbulence in the behind that cuts out rising portions, can improve under the per unit flowing resistance heat transfer property (promptly, suppress the increase of flowing resistance as much as possible, can improve heat transfer property simultaneously).And, about the flow direction downstream of air-flow cut out rising portions (for example be configured in air-flow flow direction downstream cut out rising portions 4c, 4f), can not make the excessive height that cuts out rising portions owing to the guide effect of flow direction rear side that hope easily obtains near the air-flows the heat-transfer pipe 3 are directed to the air-flow of heat-transfer pipe 3 from thermofin surface 2b, thus, can improve under the per unit flowing resistance heat transfer property (promptly, obtain guide effect as much as possible, can suppress the increase of flowing resistance simultaneously).
Like this, in the fin tube heat exchanger 1 of present embodiment, can realize simultaneously can realizing high performance based on heat transfer property that cuts out rising portions 4a～4f and performance of ventilating.
But, in the fin tube heat exchanger 1 of present embodiment, is prerequisite with rear end height b than front end height a height, use the relation of above-mentioned average height H and spacing of fin FP, so, for example, must increase the rear end height b that cuts out rising portions cutting out under the low-down situation of front end height a of rising portions, thus, cutting out the ridge of rising portions and thermofin surface 2b angulation is that tiltangle (with reference to Fig. 5) increases.Here, the ridge that respectively cuts out rising portions 4a～4f is meant, connect front end 5a～5f of respectively cutting out rising portions 4a～4f apart from the end of thermofin surface 2b farthest side and respectively cut out the line of rear end 6a～6f of rising portions 4a～4f apart from the end of the surperficial 2b farthest side of thermofin.And tiltangle is respectively to cut out the ridge of rising portions 4a～4f and the angle of thermofin surface 2b.
But, when this tiltangle is excessive, heat transfer property under the per unit flowing resistance reduces (with reference to Fig. 7), obstruction by with rear end height b than front end height a height be prerequisite, the relation of using above-mentioned average height H and spacing of fin FP improves the heat transfer property under the per unit flowing resistance, so, preferably tiltangle is provided with restriction, keeps heat transfer property under the per unit flowing resistance than the highland.
Therefore, the present application people estimates the relation of the heat transfer property under tiltangle and the per unit flowing resistance, discovery is removing the increment rate Δ Pa that has added the flowing resistance when cutting out rising portions between the value (Δ Pa/ Δ ha) and tiltangle that obtains with the increment rate Δ ha that has added the heet transfer rate when cutting out rising portions, have relation shown in Figure 7, and derived and to be scopes than the tiltangle that heat transfer property under the per unit flowing resistance is kept on the highland less than 30 degree according to this relation.
And, in the fin tube heat exchanger 1 of present embodiment, be configured to tilt so that near the air-flows the heat-transfer pipe 3 are directed to a plurality of rising portions 4a～4f that cut out of flow direction rear side of the air-flow of heat-transfer pipe 3 at each with respect to the flow direction of air-flow, further use the condition of above-mentioned tiltangle, so, can obtain improving the effect of the heat transfer property under the per unit flowing resistance reliably by the relation of using above-mentioned average height H and spacing of fin FP.
And, in the present embodiment, suppose only stipulating each shape that cuts out rising portions 4a～4f (promptly, only use the relation of above-mentioned average height H and spacing of fin FP, perhaps only use the relation of above-mentioned average height H and spacing of fin FP and the condition of above-mentioned tiltangle) situation under, for example, may produce the 1st the high situation of height that cuts out rising portions that cuts out rising portions that cuts out the flow direction upstream side of air-flow among rising portions 4a～4c from thermofin surface 2b from the flow direction downstream of the aspect ratio air-flow of thermofin surface 2b, perhaps the 2nd cut out the high situation of the height that cuts out rising portions that cuts out rising portions of flow direction upstream side of air-flow among rising portions 4d～4f etc. from thermofin surface 2b from the flow direction downstream of the aspect ratio air-flow of thermofin surface 2b, thus, the situation that forms the structure that cuts out rising portions with employing as follows in thermofin is compared, that is: a plurality of height integral body from the thermofin surface that cut out rising portions of arranging towards the downstream from the flow direction upstream side of air-flow increase gradually towards the flow direction downstream of air-flow, may be difficult to obtain near heat-transfer pipe 3 air-flows are directed to the guide effect of flow direction rear side of the air-flow of heat-transfer pipe 3.
Therefore, in the fin tube heat exchanger 1 of present embodiment, cutting out rising portions 4a～4c with the 1st is configured to, the 1st average height H that cuts out rising portions that cuts out the flow direction downstream of air-flow among rising portions 4a～4c compares with the average height H that cuts out rising portions of the flow direction upstream side of air-flow successively and increases, cutting out rising portions 4d～4f with the 2nd is configured to, the 2nd average height H that cuts out rising portions that cuts out the flow direction downstream of air-flow among rising portions 4d～4f compares with the average height H that cuts out rising portions of the flow direction upstream side of air-flow successively and increases, thus, obtain near the air-flows the heat-transfer pipe 3 are directed to the guide effect of flow direction rear side of the air-flow of heat-transfer pipe 3 easily, so, can realize the minimizing of dead water region.
