During the use of the box-type cooling tower body 101, the medium enters the disc heat exchange tube 103 through the feed pipe 102, and the spray The operation of the shower pump 105 causes the water flow inside the box-type cooling tower body 101 to enter the spray pipe 107 through the delivery pipe 106. Since the water inlet of the conical head is the large end and the water outlet is the small end, the water flow is gradually compressed when entering the conical head through the spray pipe 107, and is sprayed out after forming pressure, so that the water flow is sprayed into water droplets, so that the disc heat exchange tube 103 is sprayed more evenly. After the water contacts the air, heat exchange is carried out to generate steam. The steam evaporates and takes away the heat to cool the medium inside the disc heat exchange tube 103. The medium inside the disc heat exchange tube 103 that has absorbed heat is discharged through the discharge pipe 104.

[0027] Working principle: During the use of the box-type cooling tower body 101, the medium enters the disc heat exchange tube 103 through the feed pipe 102, the fan 203 works to promote the gas circulation inside the box-type cooling tower body 101, the filter 204 filters the input gas, and the spray pump 105 works to make the water flow inside the box-type cooling tower body 101 enter the spray pipe 107 through the delivery pipe 106. Since the water inlet of the conical head is the large end and the water outlet is the small end, the water flow is gradually compressed when it enters the conical head through the spray pipe 107, and is sprayed out after forming pressure, so that the water flow is sprayed into water droplets, so that the disc heat exchange tube 103 is sprayed more evenly, and the water exchanges heat with the air after contacting, generating steam, and the steam evaporates and takes away the heat to cool the medium inside the disc heat exchange tube 103. 03 The medium after heat absorption inside is discharged through the discharge pipe 104, and the water generated during the spraying process flows down through the filler 205. The filter plate 206 filters the impurities in the water flow. The filtered water flows into the guide pipe 208 under the action of the guide plate 207. Since the guide pipe 208 is set obliquely, it plays a guiding and buffering effect for the falling water flow. The design of the sound-absorbing cotton 209 reduces the noise interference caused by the falling water flow. The filter cartridge 210 filters the water flow inside the box-type cooling tower body 101, and performs a circulating cold shower operation under the drive of the spray pump 105 to prevent impurities in the water from entering the spray pipe 107 and causing it to be blocked.
