Abstract
The utility model relates to a composite type reinforced heat transfer fin, comprising a substrate and a bridge-shaped slot on the substrate, a heat-exchange spout opened on the substrate, one raised triangle winglet respectively arranged at the two sides of the heat-exchange spouts in the front line, wherein the slots between the two adjacent heat-exchange spouts in the back line are arranged in X shape and the adjacent bridge-shaped slots are respectively arranged at the two sides of the substrate. The composite type reinforced heat transfer fin effectively increases the heat transfer efficiency of the finned tube heat exchanger, reduces the resistance and simultaneously reduces the heat-exchange device volume of an air conditioner, a refrigeration display case and an evaporator or a condenser of a heat pump system and a middle cooler of an air compressor.
Description
Technical field
The utility model relates to a kind of thermofin, and particularly a kind of upwind and following wind direction with fin treated the thermofin of strengthening respectively with a certain discrimination, is applied to the finned tube exchanger in HVAC, air-conditioning and refrigerator display case field.
Background technology
Fin-tube heat exchanger is common a kind of heat transmission equipment in refrigeration and the HVAC industry, and cold-producing medium and cooling medium flow in pipe, and air flows outside pipe.Because the physical property of air itself, the thermal resistance in the diabatic process all concentrates on air side, is to strengthen the air side heat exchange so improve the key of heat exchange efficiency.Present main way is in air side fin to be installed, increase the heat exchange area of air, but in the plain fin pipe, because along the mobile direction of air, air is at the boundary layer of fin surface formation meeting progressive additive, the heat exchange of feasible ventilation side is at the dirty variation that flows, the heat exchange efficiency step-down of fin.For the heat exchange property of the air side of strengthening finned tube exchanger, cracking on fin is a kind of more effective means, and it has strengthened the fin heat exchange property, and the resistance of fluid increases fairly obvious simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of composite intensified thermofin that can solve problem in the background technology.
For achieving the above object by the following technical solutions: a kind of composite intensified thermofin, comprise substrate and be arranged on on-chip bridge shape and crack, offer the heat exchange mouth of pipe on the substrate, front-seat heat exchange mouth of pipe both sides respectively are provided with the triangle winglet of a projection, cracking between adjacent two the heat exchange mouths of pipe of back row is the X type and arranges that adjacent bridge shape is cracked and laid respectively at the both sides of substrate.
Described bridge shape is cracked and is cracked for substrate is provided with, bridge shape silver by supporting rack be located at crack on.
Described two triangle winglets are with respect to front-seat heat exchange mouth of pipe center line symmetric arrangement.
What described X type was arranged cracks with respect to the center line symmetry of adjacent two the heat exchange mouths of pipe of back row.
Cracking that triangle winglet of the present utility model and X-shaped are arranged is symmetrical by the center line of the heat exchange mouth of pipe along air-flow direction, front-seat heat exchange mouth of pipe both sides at thermofin, air-flow produces vertical whirlpool when flowing through, between thermofin, heat exchange tube wall and triangle winglet, form an accelerated passage simultaneously, strengthen the mixing of cold fluid and hot fluid, thus enhanced heat exchange; In back row's heat exchange mouth of pipe both sides of thermofin, the slitted fin of projection is staggered to X-shaped up and down, makes that the boundary layer of flowing is constantly destroyed, and the disturbance of the convection cell that cracks simultaneously increases, thereby has strengthened the heat exchange of heat exchanger tube.In addition, crack by rational layout, it is less that its resistance is increased, good effect of heat exchange.The utility model can effectively increase finned tube exchanger heat transfer efficiency, reduce resistance, simultaneously can reduce the evaporimeter of air-conditioning, refrigerator display case and heat pump or the heat transmission equipment volumes such as intercooler of condenser and air compressor.

Fig. 2 is a front view of the present utility model;
Fig. 3 is that the A-A of Fig. 2 is to profile.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of composite intensified thermofin comprises substrate 2 and is arranged on on-chip bridge shape and cracks 4, also offer the heat exchange mouth of pipe on the substrate 2, among the figure wind direction from left to right, the front-seat heat exchange mouth of pipe 1 is in upwind, back row's heat exchange mouth of pipe 1 ' at a disadvantage to; 1 mouthful of both sides of front-seat heat exchanger tube respectively are provided with the center line M symmetric arrangement of little 3 wings of 3, two triangles of a triangle winglet that raises up with respect to the front-seat heat exchange mouth of pipe 1, and it is 10 °～50 ° that triangle winglet 3 comes the angle of flow path direction with air-flow; , center line N is the center of circle connecting line of adjacent two the heat exchange mouths of pipe 1 ' of back row, bridge shape is cracked and 4 is the symmetric arrangement of X type with respect to center line N and center line M, adjacent bridge shape 4 both sides that lay respectively at substrate 2 of cracking.
Described bridge shape is cracked and is cracked for substrate is provided with, bridge shape silver by supporting rack be located at crack on; The heat exchange mouth of pipe can be processed into shapes such as circle, ellipse as required; Can be that a unit makes product or the cubic extension product that two sides are extended with the enhanced heat transfer fin of present embodiment; Also can make the enhanced heat transfer fin of some present embodiments, be used in combination.
The course of work: in when work, heat exchanger tube vertically passes the heat exchange mouth of pipe on the thermofin, the heat exchanger tube inside refrigerant liquid of flowing through, and air dielectric is walked outside the pipe.Air-flow produces vertical whirlpool when flowing through both sides triangle winglet, form an accelerated passage simultaneously between heat exchange fin, heat exchange tube wall and triangle winglet, postpones boundary layer separation, strengthens the mixing of cold fluid and hot fluid, thus enhanced heat exchange.When the bridge shape of air-flow wind direction under flowing through is cracked, because bridge shape is cracked and is staggered to X-shaped up and down, the concertedness of fluid velocity and thermograde is improved, resistance increase simultaneously is less, thereby has strengthened the heat exchange of finned tube.
