Embodiment 1
[0039] Such as Figure 1 to Figure 3 As shown, the present invention provides a high-temperature waste gas cooling and heat exchange device for a polyimide film casting machine, including a base plate 1 and an air supply pipe 4, and fixing holes 8 are provided on both sides of the base plate to facilitate fixing the device. There are baffles 2 near the two ends on the top, and the general baffles can be integrally formed with the bottom plate, and of course can also be fixed by welding or other existing methods. There is no specific limitation here; the uniformity between the two baffles A plurality of cooling fins 3 are provided, and the air supply pipe passes through the baffle plate and the heat dissipation fins and is connected with the baffle plate and the heat dissipation fins, wherein the air supply pipe is arranged parallel to the bottom plate; The plate and the bottom plate are vertically arranged; the inside of the air supply pipe is provided with a heat exchange tub...
Embodiment 2
[0049] Embodiment 2 has roughly the same structure as Embodiment 1, except that: the heat sink extends into the air supply pipe to connect with the heat exchange pipe; the heat sink is provided with a vent 7, and Image 6 , for ease of production, see Figure 5 with Image 6 , multiple cooling fins located on the same cross section can be arranged circumferentially on the air supply pipe;
[0050] There are two ways to use the high-temperature exhaust gas cooling and heat exchange device of the polyimide film salivating machine:
[0051] The use mode 1 is the same as that of Example 1, except that the cooling liquid cools the high-temperature exhaust gas while dissipating heat due to the connection between the cooling fin and the heat exchange tube, so that the heat exchange fin dissipates heat faster and further improves the efficiency of the high-temperature exhaust gas. Heat exchange effect;
[0052] Use method 2 is to connect one end of the heat exchange tube to the fan...
Embodiment 3
[0054] The structure of the third embodiment is roughly the same as that of the second embodiment, the difference is that no vent is provided, but the heat sink is designed as follows, see Figure 7 , the heat sink includes a first heat dissipation portion 3-1 and a second heat dissipation portion 3-2, the width of the first heat dissipation portion is greater than the width of the second heat dissipation portion, and the second heat dissipation portion extends to the The air supply pipe is internally connected with the heat exchange pipe.
