Locking components for fixing the side plates 6 are provided on the other two outer walls of the inverter housing 1. The two hot fluids are respectively added into the first hot fluid pipe 2 and the second hot fluid pipe 4 through the pipe openings located above the first hot fluid pipe 2 and the second hot fluid pipe 4, so that the hot fluid flows in the first hot fluid pipe 2 and the second hot fluid pipe 4. At the same time, cold fluid is added into the inverter housing 1 through the cold fluid inlet pipe 8, so that the cold fluid can cool down the two hot fluids at the same time, thereby improving the use effect of the cold fluid and saving energy.

[0025] In the utility model, the spoiler assembly includes a plurality of baffles 11, and the plurality of baffles 11 are welded in the variable frequency heat exchanger housing 1. The tops of the plurality of baffles 11 are provided with round holes 12. The plurality of baffles 11 are evenly distributed, and the plurality of round holes 12 are staggered. After the cold fluid enters the variable frequency heat exchanger housing 1, the cold fluid will flow to the bottom of the variable frequency heat exchanger housing 1 through the round holes 12 on the baffles 11. At the same time, the cold fluid will be spoiled under the action of the baffles 11, so that the cold fluid is fully in contact with the first hot fluid pipe 2 and the second hot fluid pipe 4, so that the cold fluid can be used to the maximum extent, further improving the use effect of the cold fluid. The locking assembly includes a plurality of slides 13, a plurality of The slide 13 is evenly welded to the other two outer walls of the variable frequency heat exchanger housing 1, and two sliders 15 are slidably connected in the multiple slides 13. One side of the multiple sliders 15 is rotatably connected with an L-shaped card plate 16, and the L-shaped card plate 16 is clamped with the side plate 6. The outer walls of the variable frequency heat exchanger housing 1 on both sides are provided with adjustment components for moving the sliders 15. The adjustment components include multiple limit rings 21, and the multiple limit rings 21 are evenly welded to the other two outer walls of the variable frequency heat exchanger housing 1.

A connecting plate 20 is welded to one end of the threaded rod 18. A plurality of slides 13 are provided with a position avoidance opening 14 on one side. A plurality of sliders 15 are rotatably connected to a connecting rod 17 on the other side. The connecting rod 17 passes through the position avoidance opening 14 and is rotatably connected to the connecting plate 20. When the side plate 6 needs to be disassembled, the double-headed threaded sleeve 19 is rotated. The double-headed threaded sleeve 19 will move the threaded rod 18 outward through the threaded engagement with the threaded rod 18. The threaded rod 18 will drive the connecting plate 20 to move.

[0026] Working principle: When in use, the two hot fluids are added into the first hot fluid pipe 2 and the second hot fluid pipe 4 through the pipe openings located above the first hot fluid pipe 2 and the second hot fluid pipe 4, respectively, so that the hot fluid flows in the first hot fluid pipe 2 and the second hot fluid pipe 4, and at the same time, the cold fluid is added into the variable frequency heat exchanger shell 1 through the cold fluid inlet pipe 8, so that the cold fluid can cool down the two hot fluids at the same time, thereby improving the use effect of the cold fluid and saving energy. After the cold fluid enters the variable frequency heat exchanger shell 1, the cold fluid will flow to the bottom of the variable frequency heat exchanger shell 1 through the circular hole 12 on the baffle plate 11, and at the same time, the baffle plate 11 will disturb the cold fluid, so that the cold fluid and the first hot fluid pipe 2 and the second hot fluid pipe 4 are filled with The contact between the two parts can maximize the use of the cold fluid, further improving the use effect of the cold fluid. When the side plate 6 needs to be disassembled, the double-headed threaded sleeve 19 is rotated, and the double-headed threaded sleeve 19 will engage with the threaded rod 18 to make the threaded rod 18 move out of the double-headed threaded sleeve 19, and the threaded rod 18 will drive the connecting plate 20 to move, and the connecting plate 20 will push the slider 15 to move out of the slide 13 through the connecting rod 17.
