Abstract
The utility model discloses a heat exchanger, solving the problem of low heat exchange efficiency in the case of too small holes in conventional fins and the problem of high manufacture cost in the case of too large holes. The heat exchanger of the utility model comprises elliptical pipes and fins. The fins are provided with elliptical holes which are mated with the elliptical pipes. The fins sleeve on the elliptical pipes. The heat exchanger is characterized in that the long axis of the elliptical holes of the fins is 9.72-10.72 mm and the short axis is 4.72-5.72 mm. The heat exchanger is advantageous in that not only good heat exchange efficiency is guaranteed, but also the production cost is effectively controlled, high efficiency, low loss and excellent energy conservation are realized, the cost can be significantly reduced and good economic effect is achieved.
Description
Technical field
The utility model relates to a kind of elliptic heat pipe heat exchanger.
Background technology
Since reform and opening-up, China's rapid economic development, promote Chinese refrigerating and air conditioning industry all-round developing, along with China's economic construction scale continuous expansion, make the production of all types of industries freezing air conditioner equipment step into development climax, make China reach the world-class manufacture scale of freezing air conditioner equipment, at aspects such as properties of product, product quality and technical merits, had and developed fast and improve.Our significant problem of developing the economy using energy-saving and emission-reduction as China and must face and solve of the outer situation demands of Present Domestic.Energy-saving and emission-reduction have been classified as to the fundamental state policy of China.Country's energy consumption per unit during " 12 " will lower 20%, and total emissions of major pollutants reduces 10%.
In large-and-medium size cities, the ratio that air power load accounts for total load has reached 40% left and right at home.Can say the realization of refrigerating and air conditioning industry to the restrictive target of the determined reduction of discharging of national Eleventh-Five Year Plan, play a part crucial.For given heat exchanger, elliptical aperture finned heat exchanger needs less heat exchanger area and less fan energy consumption (cut down fan energy consumption and can reach 50%) than circular hole finned heat exchanger, and oval tube heat exchanger improves more than 15% than pipe heat exchanger heat exchange amount.Oval tube heat exchanger has more obvious advantage than pipe heat exchanger: the firstth, and heat transfer effect improves.The secondth, elliptical tube flows outside characteristic spy is good.The 3rd is to make design of heat exchanger structure more compact, and under identical circulation area, elliptical tube heat transfer perimeter is long, and heat exchange area is corresponding increase also, also allows to arrange compactlyer in structure, makes the heat exchange amount of unit volume increase simultaneously.
On fin, offer some holes, oval pipe passes from hole, heat on oval pipe is passed to fin to be distributed, oval pipe size is also little for Kong Tai little on fin, heat exchange efficiency is also low like this, if the Kong Tai great on fin, the size of oval pipe is also large, can increase manufacturing cost like this.
Summary of the invention
The purpose of this utility model is to provide a kind of heat exchanger, can effectively solve on existing fin the too little heat exchange efficiency of hole dimension not high, the problem that the excessive manufacturing cost of hole dimension is too high.
In order to address the above problem, the utility model is achieved through the following technical solutions: a kind of heat exchanger, comprise oval pipe, fin, in described fin, be provided with the slotted eye with oval pipe adaptation, described fin is set on oval pipe, it is characterized in that: the major axis of the slotted eye of described fin is 9.72mm～10.72mm, minor axis is 4.72mm～5.72mm.
Preferably, the major axis of the slotted eye of described fin is 10.22mm, and minor axis is 5.22mm.
Preferably, described fin comprises slotted eye, flow-disturbing moulding section, and described slotted eye and flow-disturbing moulding section are staggered, and the line of centres of the slotted eye of described adjacent two row becomes equilateral triangle to be staggered.
Preferably, the pitch-row of described slotted eye is 20mm～22mm, and row distance is 17.2mm～19.2mm.
Preferably, the pitch-row of described slotted eye is 21mm, and row distance is 18.2mm.
Preferably, described flow-disturbing moulding section is shaped as out bridge type or flap type.
Preferably, the thickness of described fin is 0.105mm～0.25mm.
Preferably, the thickness of described fin is 0.115mm or 0.12mm or 0.13mm or 0.15mm or 0.25mm.
Preferably, described oval pipe adopts
circular copper pipe process.
Preferably, described oval pipe adopts
circular copper pipe process.
Compared with prior art, the utility model has the advantages that: both guarantee good heat exchange efficiency, effectively controlled again production cost, efficient low-loss, energy saving is high, can significantly reduce costs, and has good economic effect.
Accompanying drawing explanation
Fig. 1 is fin structure schematic diagram of the present utility model.
Fig. 2 is oval pipe structural representation of the present utility model.
Fig. 3 is the structural representation that the utility model oval pipe coordinates with fin.
The specific embodiment
Below with reference to Fig. 1-Fig. 3, describe according to the heat exchanger of the utility model embodiment.As shown in Fig. 1-Fig. 3, the heat exchanger of the utility model embodiment comprises oval pipe 1, fin 2, is provided with the slotted eye 21 with oval pipe 1 adaptation in fin 2, and fin 2 is set on oval pipe 1.
The major axis α of slotted eye 21 is 9.72mm～10.72mm, and minor axis β is 4.72mm～5.72mm, and wherein the major axis α when slotted eye 21 is 10.22mm, the low cost of manufacture of heat exchanger when minor axis β is 5.22mm, and heat exchange efficiency is good.
The pitch-row γ of slotted eye 21 is 20mm～22mm, and row are 17.2mm～19.2mm apart from δ, and wherein the pitch-row γ when slotted eye 21 is 21mm, the heat exchanger excellent in heat dissipation effect that row are 18.2mm apart from δ, low cost of manufacture.
