Embodiment 1

[0038] Please refer to figure 1 , the present embodiment provides an air cooler 100, the air cooler 100 includes a heat exchange unit 110, an air filter 120, a housing 130 and a fan 140 for producing air flow.

[0039] Specifically, the heat exchange unit 110 includes a main heat exchange structure 111 , first fins 112 and second fins 113 . The heat exchange main structure 111 has a plurality of air flow channels 111a and a plurality of heat exchange medium flow channels 111b arranged alternately, the first fins 112 are arranged in the air flow channels 111a, and the second fins 113 are arranged in the heat exchange medium flow channels 111b The heat exchange main structure 111 has a flow divider 111c and a confluence 111d respectively arranged at both ends of the heat exchange medium channel 111b, the flow divider 111c has a heat exchange medium inlet 111c1, and the confluence 111d has a heat exchange medium outlet 111d1.

[0040] Specifically, the housing 130 has an air inl...

Embodiment 2

[0086] see Figure 4 , this embodiment provides an air cooler 200. Compared with Embodiment 1, the difference between the air cooler 200 and the air cooler 100 is that: the air cooler 200 has two heat exchange units 110, and between the two heat exchange units 110 The two heat exchange units 110 form a roughly “V” shaped heat exchange cover 210 connected by a “V”-shaped draft tube 220 , and the heat exchange cover 210 is located on the side of the side wall 131 away from the bottom plate 132 .

[0087] In this embodiment, when the heat medium passes through the heat exchange cover 210, it will pass through two heat exchange units 110 successively, and the heat exchange effect on the heat medium can be better and more fully through two consecutive heat exchanges. On the other hand, since the heat exchange cover 210 is in a roughly "V" shape, the number of heat exchange units 110 of the air cooler 200 can be increased, the heat exchange area can be increased, and the heat exchan...

Embodiment 3

[0091]see Figure 5 , this embodiment provides an air cooler 300. Compared with Embodiment 1, the difference between the air cooler 300 and the air cooler 100 is that: the heat exchange unit 110 of the air cooler 300 is roughly flat and has multiple, multiple The heat exchange unit 110 incorporates a rectangular heat exchange ring. The air filter 120 is also in the shape of a surrounding rectangle, that is, the air filter 120 is sheathed on the outer periphery of the heat exchange ring.

[0092] The air cooler 300 can improve the utilization rate of the air filter 120 as much as possible, so that the air filter 120 corresponds to the heat exchange unit 110 as much as possible, and can increase the overall heat exchange area of ​​the air cooler 300, and improve the performance of the air cooler 300. The total efficiency of heat exchange.

[0093] It should be noted that, in other embodiments of the present invention, the heat exchange unit 110 can also be surrounded to form a...

Abstract

The invention discloses an air cooler and a zero-emission circulating water cooling system, and relates to the technical field of cooling. The air cooler comprises a fan, an air filter, a heat exchange unit and a shell. The heat exchange unit includes first fins, second fins, and a heat exchange main structure with multiple air runners and multiple heat exchange medium runners. The air runners are provided with first fins; and the heat exchange medium runners are provided with the second fins. Shunts and junction stations are respectively arranged at two ends of the heat exchange medium runners; the shunts have heat exchange medium inlets; and the junction stations have heat exchange medium outlets. The shell has an intake port and an exhaust port; the air filter is arranged in the intake port; the heat exchange unit is arranged in the exhaust port; and the air runners communicate an inner cavity of the shell with the external. The air cooler is high in overall heat exchange efficiency and excellent and stable in heat exchange effect. The zero-emission circulating water cooling system comprises an internal circulation cooling system and an external circulation cooling system for providing cooling capacity to the internal circulation cooling system. The internal circulation cooling system is provided with the air cooler. The air cooler is excellent in refrigerating effect, achieves zero emission, and saves water resources.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to an air cooler and a zero-emission circulating water cooling system. Background technique [0002] The air cooler uses ambient air as the cooling medium, and the air flows through the finned tubes to cool or condense the high-temperature process fluid. [0003] In the chemical industry, electric power, coal and other industries, there is a large amount of waste heat that needs to be cooled, and the amount of cooling water is huge. Although most enterprises have changed the cooling water to circulating cooling water, the amount of fresh water is still very large, and water resources are increasingly scarce. Today, huge water consumption seriously hinders and restricts the development of enterprises. Air coolers are widely used in industrial installations in various industries because of their remarkable water-saving performance, especially in the northwest region where water is sc...
