Description

Technical Field

[0001] The utility model relates to an evaporative condenser, in particular to a direct-discharge indirect evaporative condenser. Background Art

[0002] The direct-discharge indirect evaporative condenser usually includes an evaporator and a condenser. Hot water vapor is introduced into the evaporator through a heat exchanger to evaporate and generate steam. After the steam enters the condenser, it is cooled and condensed into liquid through a cooling pipe.

[0003] In conjunction with the publication (announcement) number: CN114234492A, the publication (announcement) date: 2022-03-25, an evaporative condenser is disclosed, comprising a middle condenser pipe portion located in the middle of the cross-section of the cooling air channel and an outer condenser pipe portion located at the edge of the cross-section of the cooling air channel. In the direction of cooling air flow, the cooling efficiency per unit cross-section of the middle condenser pipe portion is at least greater than the cooling efficiency per unit cross-section of the outer condenser pipe portion on one side. In this evaporative condenser, because the cooling efficiency per unit cross-section of the middle condenser pipe portion is at least greater than the cooling efficiency per unit cross-section of the outer condenser pipe portion on one side, it can correspond to the wind flow distribution method to ensure that the cooling effects in the middle and the edge are close. In summary, the evaporative condenser can effectively solve the problem of waste of condenser pipelines or waste of refrigerant. The present invention also discloses an evaporative condenser unit including the above-mentioned evaporative condenser.

[0004] In the prior art including the above-mentioned patents, the role of the condenser in the direct-discharge indirect evaporative condenser is particularly important. Direct heat exchange is the way of heat exchange of the condenser, but the refrigerant utilization rate of this method is relatively limited. How to further improve the refrigerant utilization rate is expected to be well solved! Utility Model Content

[0028] The port of the ceramic inner shell 4 is provided with an air guide cover 5 connected to the air outlet of a fan unit 2. The cross-section of the air guide cover 5 is an isosceles trapezoidal structure, and the interior is provided with partitions 51 which are parallel to the two sides of the isosceles trapezoidal structure and arranged in a linear array from the two sides to the axis. The multiple partitions 51 make the air guide cover 5 form a central air duct 52 and an inclined air duct 53 which is arranged symmetrically about the center of the central air duct 52.

[0029] In the above technology, the condenser tube group 3 is wrapped by the ceramic inner liner cover 4, and then the air flow is blown in by the fan unit 2 through the wind guide cover 5 for guidance. The wind is diffused by the central air duct 52 and blown directly to the condenser tube group 3, and the two groups of inclined air ducts 53 arranged in a mirrored manner are facing the ceramic inner liner cover 4 and the condenser tube group 3 close to the end of the ceramic inner liner cover 4, thereby maximizing the cooling effect on the condenser tube group 3, thereby achieving the purpose of improving the utilization rate of the refrigerant.

[0030] It should be noted that the cross section of the central air duct 52 in the above embodiment is an isosceles trapezoidal structure.

[0031] Further, combined with Figure 3 It can be seen that the air outlet of the inclined air duct 53 faces the side wall of the ceramic inner tank cover 4.

[0032] Combination Figure 2 It can be seen that the condenser tube group 3 includes a plurality of cold plates 31 arranged in a matrix, and the cold plates 31 are aluminum alloy plates. A curved pipe 32 is arranged between two rows of cold plates 31 along the vertical horizontal plane, and the curved pipe 32 maintains a predetermined distance from the cold plates 31.
