Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically to an exhaust pipe structure for a heat exchanger. Background Technology
[0002] The exhaust pipe of a heat exchanger plays a crucial role in the heat exchange system. The exhaust pipe can effectively expel hot gas from the outside of the system, ensuring the normal operation of the system, balancing the internal pressure of the heat exchanger, expelling non-condensable gases, and maintaining efficient heat exchange inside the heat exchanger.
[0003] Existing heat exchanger exhaust pipe structures, such as the Chinese utility model patent CN218565577U entitled "An Exhaust Pipe Assembly for an Air Conditioner Heat Exchanger," include a main pipe. A crossbeam is fixedly connected to the inner walls of the main pipe on both sides near the center of its bottom. A rotating shaft is movably connected to the top of the crossbeam near its center. A threaded rod is fixedly connected to the top of the rotating shaft, and a top plate is fitted onto the threaded rod near its bottom. The return spring, arc-shaped baffle, and bevel gear in this patent solution are complex, resulting in high production and maintenance costs. They are also prone to damage during use, and the structural design is unreasonable, easily clogging and difficult to clear. Therefore, a new exhaust pipe structure for heat exchangers needs to be designed to address these problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The exhaust pipe structure of this heat exchanger adopts a new structural design.

First, close the control valve to increase the pressure in the main exhaust pipe on one side of the control valve, and then open the control valve to quickly dredge the drain pipe by using air pressure, ensuring that the overall device can work efficiently.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides a technical solution: an exhaust pipe structure for a heat exchanger, including a main exhaust pipe 1, a control valve 2, a clamp 3, a support rod 4, a movable plate 5, a base plate 6, positioning bolts 7, positioning nuts 8, a track groove 9, anchoring nails 10, a drain pipe 11, a baffle 12, a clamping plate 13, a locking bolt 14, and a plug 15. The control valve 2 is installed on the main exhaust pipe 1, and the clamp 3 is installed on the outside of the main exhaust pipe 1. The support rod 4 is rotatably installed on the bottom of the outer wall of the clamp 3. The bottom end of the support rod 4 is rotatably connected to one end of the top surface of the movable plate 5. The movable plate 5 is set on the base plate. On the substrate 6, a positioning bolt 7 is installed through a hole at the other end of the substrate 6. A positioning nut 8 is installed at the top of the positioning bolt 7. The bottom end of the positioning bolt 7 is in contact with the inner wall of the track groove 9. The track groove 9 is located at the top end of the substrate 6. An anchoring nail 10 is installed through the end of the substrate 6. A drain pipe 11 is fixedly installed at the bottom of the end of the main exhaust pipe 1. A baffle 12 is fixedly installed at the top of the end of the main exhaust pipe 1. A clamping plate 13 is installed at the top end of the baffle 12. A locking bolt 14 is threadedly installed at the top end of the clamping plate 13. A plug 15 is fixedly installed at the bottom end of the clamping plate 13.
[0022] In this example, the clamp 3 and the support rod 4 are symmetrically distributed about the center of the control valve 2, and the support rod 4 is symmetrically distributed about the clamp 3. The above structural design enables the clamp 3, the support rod 4 and the bottom structure to stably support and position the main exhaust pipe 1.
[0023] The centers of the support rod 4, movable plate 5, base plate 6 and positioning bolt 7 are all on the same vertical plane. The positioning bolt 7 is slidably connected to the track groove 9. The above structural design allows the positioning bolt 7 to slide along the track groove 9, adjust the horizontal position of the movable plate 5, thereby adjusting the tilt angle of the support rod 4, adjusting the installation height of the main exhaust pipe 1, and ensuring that the main exhaust pipe 1 and the drain pipe 11 can work normally.
[0024] The length of the track groove 9 is greater than 1 / 4 of the length of the substrate 6. The front view profile shape of the track groove 9 is a "丄" shape. The above structural design can prevent the positioning bolt 7 from slipping out of the track groove 9 and ensure that the positioning bolt 7 and the movable plate 5 can be adjusted horizontally within a sufficient range.
[0025] The drain pipe 11 is inclined and is evenly distributed. The bottom end of the drain pipe 11 is higher than the top surface of the substrate 6. The above structural design enables the condensed water in the main exhaust pipe 1 to be quickly and smoothly discharged, preventing the accumulation of condensed water in the main exhaust pipe 1 and affecting the smooth exhaust.
[0026] The side view shape of the baffle 12 is an inverted "凵" shape, and the front view shape of the baffle 12 is a right trapezoid. The inner wall of the baffle 12 is in contact with the side surface of the clamping plate 13, and the inner wall of the clamping plate 13 is in contact with the top of the baffle 12. The above structural design enables the clamping plate 13 and the plug 15 to be stably installed, ensuring the sealing effect on the end of the main exhaust pipe 1.
[0027] Working principle: During installation, first install the hoop 3 on the main exhaust pipe 1 on both sides of the control valve 2, and then, according to the installation environment of the installation surface, push Figure 2 the symmetrically distributed movable plates 5 on both sides to move the positioning bolts 7 along the track groove 9 closer, drive the support rods 4 to stand up, lift the main exhaust pipe 1 to an appropriate height, rotate the positioning nut 8 to squeeze the movable plate 5 to fit and fix with the top surface of the substrate 6, and connect and fix the substrate 6 with the installation surface through the anchor pins 10;
[0028] During use, unscrew the locking bolt 14 from the top of the baffle 12, pull out the clamping plate 13 to the right, separate the clamping plate 13 from the baffle 12, and separate the plug 15 from the end of the main exhaust pipe 1. The hot air discharged from the heat exchanger smoothly discharges from the end of the main exhaust pipe 1, and the condensed water generated during the discharge process quickly discharges through the evenly distributed drain pipes 11. When the drain pipes 11 are not draining smoothly, first close the control valve 2, install the clamping plate 13 and the plug 15 back to the Figure 4 state shown in the figure, screw down the locking bolt 14 to squeeze the baffle 12 to fix the positions of the clamping plate 13 and the plug 15, and the plug 15 seals the end of the main exhaust pipe 1. Then immediately open the control valve 2. The hot air that is temporarily pressurized due to the temporarily closed discharge path quickly flows towards the drain pipes 11, and uses the air pressure to discharge the blocked debris in the drain pipes 11. This method can also discharge the impurities in the main exhaust pipe 1. Then remove the locking bolt 14, remove the clamping plate 13 and the plug 15 from the baffle 12, and the whole device can work normally again. This is the working principle of the exhaust pipe structure of this heat exchanger.
