Please continue the 6-1 to 6-5 with reference to figure, Fig. 6-1 is the first At The Height water droplet force analysis comparison diagram among Fig. 6; Fig. 6-2 is the second At The Height water droplet force analysis comparison diagram among Fig. 6; Fig. 6-3 is third high degree place water droplet force analysis comparison diagram among Fig. 6; Fig. 6-4 is the 4th At The Height water droplet force analysis comparison diagram among Fig. 6; Fig. 6-5 is the 5th At The Height water droplet force analysis comparison diagram among Fig. 6.
Fig. 6-1 is to 6-5, suppose that Ft θ, Fn θ, G θ, Gt θ represent respectively among the utility model embodiment suffered viscous force, pressure, gravity and the gravity component on the water droplet direction of motion of water droplet on the header 21, θ 1, θ 2, θ 3, θ 4, θ 5 represent respectively in the present embodiment angle of five differing heights position G θ and Ft θ; Ft β, Fn β, G β, Gt β represent respectively water droplet on the general header 11 suffered viscous force, pressure, gravity and gravity at the component of the water droplet direction of motion, and β 1, β 2, β 3, β 4, β 5 represent respectively the G β of five differing heights position water droplets on the general header 11 and the angle of Ft β.
The suffered viscous force of water droplet is opposite with the direction of motion of water droplet, gravity on the direction of motion component and viscous force to make a concerted effort be the power of the water droplet direction of motion.The computing formula of Gt θ and Gt β is respectively Gt θ=G θ * cos θ, Gt β=G β * cos β.Relatively θ 1 and β 1, θ 2 and β 2, θ 3 and β 3, θ 4 and β 4, θ 5 and the β 5 at header 11 and 21 5 differing heights places of header clearly can find out θ 1＜β 1, θ 2=β 2, θ 3 ≈ β 3, θ 4＜β 4, θ 5＜β 5.Therefore at height and position place shown in the first height a, the 4th height d, the 5th height e, satisfy relational expression: Gt θ＞Gt β, namely compared to general header 11, among the utility model embodiment on the header 21 in the position, three places shown in this Fig. 6, the component of gravity on the water droplet direction of motion has increased.Height and position shown in the second height b and the third high degree c satisfies relational expression Gt θ=Gt β, and namely the component along the direction of motion equates substantially.When the drainage ridge 211 of header 21 flowed downward during the above analysis, water droplet were implemented along the utility model, the component of gravity on the water droplet direction of motion was increased.
By the can visually see flow tendency of condensed water of Fig. 7 and Fig. 8, Fig. 7 drainage ridge of header that is condensation flow to Fig. 2 and the structural representation of discharging; Fig. 8 header that is condensation flow to Fig. 1 and the structural representation of discharging.Be Fig. 7 and Fig. 8 show drainage ridge 211 is set after, flowing of condensed water is more smooth and easy, black arrow all represents the flow direction of condensed water among two figure.Therefore, for above-described embodiment, the header 21 that drainage ridge 211 is set has reduced the viscous force of condensed water, increased the component of gravity in the condensed water direction of motion, accelerated the defluent speed of condensed water, can discharge in time rapidly so that flow to the condensed water of header 21, solved condensed water gather in header 21 middle and lower parts and water appears flying, the problems such as causing the heat exchanger mechanically deform of freezing.
For above-described embodiment, can compare simultaneously β 4 and β 5, β 4＜β 5, on general header 11, along with condensed water to flows, gravity is more and more less at tangential component, be reduced to 0 to bottommost, this moment, viscous force was opposite with gravity direction, showed as the adhesive force to water droplet and header 11 bottom contact-making surfaces, only have when gravity greater than adhesive force the time water droplet can flow down, as shown in Figure 4.For embodiment of the present utility model, because the bottom of drainage ridge 211 sidewalls is planes, θ 4=θ 5 then, water droplet flow to bottom always, the component of gravity on the direction of motion is constant all the time, and water droplet can accelerate to flow always, until bottom, water droplet is easy to just can flow down along drainage ridge 211, as shown in Figure 4.
Can expect, the sidewall of drainage ridge 211 also is not limited to shape shown in Figure 4, and the curvature of its sidewall gets final product less than header 21 periphery curvature, certainly, when drainage ridge 211 sidewalls are plane, can reach the effect that the described further quickening condensed water of this section flows.On sidewall is plane basis substantially, in order successfully to flow to drainage ridge 211 so that flow to the condensed water of header 21, the top of drainage ridge 211 sidewalls can possess certain radian, so that condensed water can transit to drainage ridge 211 from header 21 peripheries preferably swimmingly.All can find out from Fig. 4 and Fig. 5, drainage ridge 211 upper portion side wall possess certain flexibility, and satisfy curvature less than header 21 periphery curvature, condensed water can be smooth and easy and be accelerated to flow to by a small margin the top of drainage ridge 211, the middle and lower part of drainage ridge 211 sidewalls is plane, then condensed water continues significantly to flow to the crestal culmination 2111 of drainage ridge 211 with accelerating, and then discharges.
Are connected the transition of circumference with header and connect and convenient processing in order to realize drainage ridge 211, the structural design of drainage ridge 211 and header 21 as shown in Figure 5, the monolithic construction that drainage ridge 211 and header 21 form for cutting, can find out in conjunction with Fig. 4, owing to need guarantee that the curvature of drainage ridge 211 sidewalls is less than the curvature of header 21 peripheries during cutting, if the pore cross section of header 21 still is circular, header 21 internal diameters that then drainage ridge 211 sidewalls are corresponding will diminish, in order to guarantee the intensity of header 21 tube walls, it can not be circular that the header 21 pore cross sections that cutting forms form, among Fig. 4, inboard wall of tube body corresponding with drainage ridge 211 sidewalls on the header 21 is to central elevation, pipe thickness loss when forming drainage ridge 211 to remedy, guarantee the intensity of body, in fact, the sidewall on drainage ridge 21 tops of this moment has served as the tube wall of header 21.Drainage ridge 211 and header 21 also can form monolithic construction by casting.Drainage ridge 211 and header 21 also can be split-type structurals, can only comprise lower end part triangular in shape among Fig. 4 such as drainage ridge 21, directly the drainage ridge of this structure are connected on the header 11 among Fig. 1 also to be fine.
In addition, because condensed water generally especially compiles the bottom in the middle and lower part of header 21, then the root of drainage ridge 211 two sides can extend respectively and be connected to mutually the crestal culmination 2111 of the below formation drainage ridge 211 of header 21 from the both sides at header 21 middle parts.Then condensation flow is to the middle part of header 21, can accelerate to flow, 211 settings like this of drainage ridge can either solve general header 11 middle and lower part condensed water accumulation problems, do not affect again the grafting (being positioned at the top of header 21 for the slot 212 of heat exchanger tube 23 grafting) of header 21 and heat exchanger tube 23.The root of drainage ridge 211 two sides also can extend from the top of header 211, as shown in Figure 4, below header 21 center lines, the flow process of condensed water is roughly suitable with the flow process on general header 11, and more than header 21 center lines, the flow process of condensed water is less than the flow process on general header 11, on the whole, the flow process of condensed water is reduced in the present embodiment, reaches the purpose of the further raising condensed water velocity of discharge.
For the various embodiments described above, the two side of drainage ridge 211 can be with respect to the radial symmetric setting of header 21.Then condensed water is when the top of header 21 flows to the both sides of drainage ridge 211, and it is roughly consistent that the flow tendency of condensed water can keep, and reaches same drainage effect, in order to avoid one-sided generation seeping phenomenon.Better for the drainage effect that makes drainage ridge 211 both sides, the angle α of both sides sidewall preferably satisfies following condition: 30 °≤α≤60 °, please refer to Fig. 9, and Fig. 9 is the structural representation at drainage ridge crestal culmination place among Fig. 4.In this angular interval, the partical gravity of condensed water can guarantee the smooth discharge of condensed water, and the volume size of drainage ridge 211 also is suitable for installing, and can not interfere with other members.Certainly, for the various embodiments described above, the both sides of drainage ridge also can asymmetricly arrange, when heat exchanger is obliquely installed, all can realize the purpose that condensed water is discharged fast for guaranteeing drainage ridge 211 two sides, can be according to the angle of heat exchanger inclination, size and the angle of design drainage ridge 211 two sides.
In addition, in above-described embodiment, drainage ridge 211 both sides sidewalls join and are straight line, be that crestal culmination 2111 is wire, on cross section, roughly show as triangle, as shown in Figure 4, when then condensation flow is to crestal culmination 2111, the face that condensed water contacts with drainage ridge 211 is approximately linear face, and suffered adhesive force is very little, can relatively easily flow down.Can understand with reference to Figure 10 and Figure 11 the structural representation at Figure 10 drainage ridge crestal culmination place of header bottom that is condensation flow to Fig. 4; The structural representation of Figure 11 header bottom that is condensation flow to Fig. 1.Among Figure 11, the contact-making surface of condensed water and header 11 bottoms is larger, and adhesive force is larger, and the discharge of condensed water is difficulty comparatively.
