Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described.
According to simulation calculation, find due to the impact of radiator head construction, flow in each passage of radiator and the pressure of correspondence have bigger difference, and Fig. 9 is the differential pressure curve of ordinary construction charge air cooler under different operating mode between each passage, the operating mode that wherein the corresponding thermal medium flow of Case9 is larger.As seen from Figure 9, under the operating mode that thermal medium bulk flow is larger, between passage, the difference of pressure reduction reaches several thousand Pa.Even if under the operating mode that flow is less, the difference of pressure reduction is also close to 400Pa.In the passage that flow is higher, pressure may reach Pa more than 2000.To the radiator of liquid-gas heat exchange, hot side pressure reaches several ten thousand by force on the order of magnitude, and the difference of pressure is more remarkable, and (Figure 10 is the velocity flow profile in the different hot-side channel of ordinary construction water tank; Flow velocity and pressure are converted, the pressure difference also highly significant between different pipe can be found).Therefore, stretching by pressure-driven pipe, reaches the object regulating fin configuration, while guaranteeing heat exchange property, can control the growth of radiator resistance pressure reduction preferably.
As shown in Figure 1, a kind of tube-fin type radiator based on thermal medium flow of the present invention, comprises thermal medium entrance 1, head tube connector 2, fin 3, stationary pipes 5, motion pipe 6, thermal medium outlet 9, afterbody tube connector 10; Thermal medium entrance 1 is connected with head tube connector 2, thermal medium outlet 9 is connected with afterbody tube connector 10, the two ends of stationary pipes 5 are connected with afterbody tube connector 10 with head tube connector 2 respectively, motion pipe 6 upper end is connected with head tube connector 2 by motion pipe upper extending section 7, and motion pipe 6 lower end is connected with afterbody tube connector 10 by motion pipe lower extending section 8; Stationary pipes 5 and motion pipe 6 are alternately arranged successively.Described stationary pipes 5, motion pipe 6 are flat tube.
As shown in Figure 2, fin 3 is in multiple " bow " font cascaded structure, and as shown in Figures 3 and 4, fin 3 is arranged in parallel, and is arranged between stationary pipes 5 and motion pipe 6, and adjacent two fins 3 respectively with the stationary pipes 5 of both sides and motion pipe 6 fixing.
As shown in Figure 8, tube-fin type radiator also comprises motion pipe-in-pipe 11, and described motion pipe-in-pipe 11 is enclosed within outside motion pipe upper extending section 7, and motion pipe-in-pipe 11 upper end is fixed on head tube connector 2, and lower end is unsettled.Motion pipe-in-pipe 11 can prevent motion pipe upper extending section 7 outwardly under the pressure effect of thermal medium.
Motion pipe upper extending section 7 and motion pipe lower extending section 8 are made by elastic plastic material, have certain elastoplasticity and rigidity.When without thermal medium, motion pipe upper extending section 7 is in compressive state, the decrement difference of the distance at two ends (under the compressive state under the distance at two ends and nature) is 1/2 of spacing of fin d, motion pipe lower extending section 8 keeps straight (Fig. 5), when thermal medium (deep fat or water) enters in motion pipe 6 by entrance 1, motion pipe upper extending section 7 is under the pressure effect of thermal medium, be elongated by original compressive state, motion pipe lower extending section 8 micro-convexes (Fig. 6), motion pipe 6 is made to drive the fin 3 be fixed on motion pipe 6 to move down, fin 3 on motion pipe 6 comes with adjacent fin 3 stagger arrangement of being fixed in stationary pipes, form stagger arrangement type fin (Fig. 7), because under the distance at the two ends under motion pipe upper extending section 7 compressive state and nature, the difference of the distance at two ends is 1/2 of spacing of fin d, the maximum displacement of motion pipe is 1/2 of finned length, both maximum radiating effect had been reached.
When cover has motion pipe-in-pipe 11, motion pipe upper extending section 7 can not convex (Fig. 8), and the move distance on vertical direction is larger, and effect is more obviously good; And Local Heat Transfer ability is promoted greatly, realize enhanced heat exchange.
Therefore, the tube-fin type radiator that the present invention proposes, according to the uninterrupted of thermal medium (deep fat or water), can realize the adjustment to fin distribution form.Near the pipe of high flow capacity, form the stagger arrangement type fin that coefficient of heat transfer is higher; And near low discharge pipe, keep the form of plain fin; Thus rationally reduce resistance dissipative, improve radiator operating efficiency.
