Description
Technical field
The present invention relates to fin tube heat exchanger, particularly have the thermofin that is configured in the air-flow, and insert thermofin and be configured in and the flow direction of the air-flow fin tube heat exchanger of a plurality of heat-transfer pipes on the direction of quadrature roughly.
Background technology
In the past, in aircondition etc., be extensive use of and have the thermofin that is configured in the air stream, and insert thermofin and be configured in and the flow direction of the air stream fin tube heat exchanger of a plurality of heat-transfer pipes on the direction of quadrature (that is, intersect fin tube heat exchanger) roughly.
In this fin tube heat exchanger, as dead water region that forms with the part of minimizing in the flow direction downstream of the air stream of the heat-transfer pipe of thermofin and the boundary layer of upgrading thermofin is the heat transfer promotion method of purpose, sometimes adopt following technology: on the position of the heat-transfer pipe both sides on thermofin surface, erect the flow direction upstream side that forms towards air stream and expand the guide fins of opening (with reference to patent documentation 1) by cutting out.
Patent documentation 1: Japanese kokai publication sho 61-110889 communique
But, the fin tube heat exchanger that will adopt above-mentioned the sort of guide fins as with aircondition etc. be representative with the situation of air as the evaporimeter of the thermophores such as cold-producing medium of thermal source under, can produce following problem: guide fins is interior to make the flowing resistance increase because the discharge water that the heat exchange of air and thermophore produces is trapped in.And, under the situation of the fin tube heat exchanger that will adopt above-mentioned the sort of guide fins as the outdoor heat converter of the outdoor unit that constitutes aircondition, sometimes remove the frost that produces on the thermofin surface by the defrosting running, but can produce the problem that drainage reduces this moment.
Summary of the invention
Problem of the present invention is, in fin tube heat exchanger, realizes heat transfer facilitation effect and drainage based on guide fins simultaneously.
The fin tube heat exchanger of the 1st aspect has: thermofin, and it is configured in the air-flow; And a plurality of heat-transfer pipes, it inserts thermofin, and is configured in and the flow direction of air-flow roughly on the direction of quadrature.On thermofin,, erect and be formed with on the thermofin surface from the flow direction upstream side of air-flow a plurality of guide fins towards the straight arrangement in downstream by cutting out in the both sides of heat-transfer pipe.The straight line that a plurality of guide fins are coupled together imaginaryly is to tilt near the side directed mode behind the flow direction of the air-flow of heat-transfer pipe of the air-flow the heat-transfer pipe with respect to the flow direction of air-flow.
In this fin tube heat exchanger, guide fins is split into a plurality of from the flow direction upstream side of air-flow towards the downstream, and, a plurality of guide fins are to tilt near the side directed mode behind the flow direction of the air-flow of heat-transfer pipe of the air-flow the heat-transfer pipe with respect to the flow direction of air-flow, therefore, mainly can obtain following effect reliably: the guide fins of the flow direction front side by the air-flow that is configured in thermofin in a plurality of guide fins is upgraded the boundary layer, and can obtain following effect: the guide fins of the flow direction rear side of the air-flow by being configured in thermofin reduces the dead water region that the part at the flow direction rear side of the air-flow of heat-transfer pipe forms, simultaneously, can easily discharge the discharge water that produces on the thermofin surface from the gap between the guide fins.Thus, can not be subjected to influence, and obtain heat transfer facilitation effect based on guide fins at the discharge water of thermofin surface generation.
And, a plurality of guide fins are arranged towards the downstream as the crow flies from the flow direction upstream side of air-flow, thus, the guide fins of flow direction rear side that is configured in the air-flow of thermofin in a plurality of guide fins has the identical inclination of guide fins with the flow direction front side that is configured in air-flow, therefore, not only can reduce the dead water region that the part at the flow direction rear side of the air-flow of heat-transfer pipe forms, and can prevent to form new dead water region in the behind of guide fins.
As mentioned above, in fin tube heat exchanger of the present invention, can not be subjected to influence at the discharge water of thermofin surface generation, and acquisition is based on the heat transfer facilitation effect of guide fins, and, can prevent to form new dead water region, therefore can realize heat transfer facilitation effect and drainage simultaneously based on guide fins in the behind of guide fins.
The fin tube heat exchanger of the 2nd aspect forms, and in the fin tube heat exchanger aspect the 1st, the height of each guide fins increases gradually towards the flow direction downstream of air-flow.
In this fin tube heat exchanger, form the shape that height increases gradually towards the flow direction downstream of air-flow by the shape that makes each guide fins, thereby can produce vertical vortex in the behind of each guide fins, therefore, can further improve heat transfer facilitation effect based on guide fins.
The fin tube heat exchanger of the 3rd aspect forms, in the fin tube heat exchanger aspect the 1st or the 2nd, be formed with draining promotion portion on thermofin, this draining promotion portion is used to make and is stranded in below the water between the guide fins mutually adjacent on the straight line flows to.
In this fin tube heat exchanger, owing between guide fins, be formed with draining promotion portion, so can further improve the drainage of thermofin.
The fin tube heat exchanger of the 4th aspect forms, and in the fin tube heat exchanger aspect the 3rd, draining promotion portion is the slit that is formed between guide fins adjacent mutually on the straight line.
