[0022] Embodiment 1:

[0023] like Figure 1-2 As shown, a constant temperature air circulation system for an electronic factory includes a heat exchanger 1, an air intake pipeline 2, an air collecting pipeline 3 and a filter unit 4. The air outlet of the heat exchanger 1 is communicated with one end of the air intake pipeline 2, and the air intake of the heat exchanger 1 is communicated with one end of the air collecting pipeline 3. The filter unit 4 is arranged inside the air collecting pipeline 3. The filter unit 4 includes a spiral pipe 41, a spiral blade 42 and a filter grid 43. Positioning rings are sleeved at both ends of the outer side of the spiral pipe 41. A sealing ring is arranged on the positioning ring. The spiral blade 42 is coaxially arranged inside the spiral pipe 41. The spiral blade 42 is connected to the inner side of the spiral pipe 41. The spiral pipe 41 is fitted with a wall, and a sealing device is provided at the fitting point of the spiral blade 42 and the spiral pipe 41. The spiral pipe 41 is provided with a plurality of placement openings at equal intervals. The filter grille 43 is installed in the placement opening through a sealing device. There are a plurality of filter grilles 43, and the plurality of filter grilles 43 are used to fill the interior of the spiral pipe 41. The filter grille 43 includes a folding frame and filter cotton arranged inside the folding frame, and the filter cotton is a multi-layer structure. The interior of the air intake pipe 2 is provided with densely distributed capillaries, and the interior of the capillaries is filled with constant temperature coolant. A temperature detector is provided at the end of the interior of the air intake pipe away from the heat exchanger 1.

[0024] like Figure 1 As shown, the gas collecting pipeline 3 collects gas and squeezes the gas into the spiral pipeline. The filtered gas in the spiral pipeline enters the interior of the heat exchanger and is reheated at a constant temperature, and then discharged. This method ensures that the amount of dust in the gas entering the air intake pipeline is low, so dust will not continue to be added to the environment through the air inlet. The dust can be collected for a long time through the setting of the gas collecting pipeline, thereby reducing the dust content inside the laboratory.

[0025] Specific implementation process: Through the filtering device installed in the air collecting pipe, the air inside the factory can be filtered during the circulation process, so that the amount of dust in the air inside the factory is reduced, ensuring the cleanliness of the factory during the air circulation process.
