Embodiment 1

[0027] refer to Figure 1 to Figure 4 , the present invention includes a water tower housing 1 with a cooling chamber 6 inside; the top of the water tower housing 1 is provided with an exhaust hole 11, and an exhaust fan 10 is provided at the exhaust hole 11;

[0028] The upper part of the water tower housing 1 is provided with a water inlet pipe 9, and the water inlet pipe 9 communicates with the shower head 7 through several branch pipes 8; the axis of the shower head 7 and the axis of the branch pipe 8 are longitudinally corresponding to each other, And the branch pipe 8 and the shower head 7 communicate with each other in a circumscribed angle; the shower head 7 is cylindrical as a whole, and one end of the shower head 7 is provided with a horizontal spray hole 13; One end of the shower head 7 is tapered, and the diameter of the tapered nozzle gradually shrinks toward the horizontal spray hole 13; the shower heads 7 are in groups of two, and the horizontal spray nozzles of...

Embodiment 2

[0047] A shower head, which is prepared according to the following process:

[0048] Take 100kg of aluminum powder, 30kg of aluminum-nickel master alloy, 10kg of aluminum-copper master alloy, and 10kg of aluminum-scandium master alloy; put them into the electric melting furnace in turn, raise the temperature, control the melting temperature to 800°C, and melt the prepared melt for 2 hours Take it out, pour it into the mold, cool to 600°C at a cooling rate of 20°C / s, hold for 120s, then cool to 400°C at a rate of 10°C / s, hold for 180s, and then cool at a rate of 10°C / s to room temperature, demoulding to obtain the blank; heating the blank to 400°C at a heating rate of 5°C / s, keeping it warm for 30 minutes, then cooling down to room temperature; then raising the temperature to 500°C at a heating rate of 10°C / s, keeping it warm for 60 minutes, and then Cool down to room temperature; remove burrs; the aluminum-nickel master alloy is AlNi10; the aluminum-copper master alloy is AlCu...

Embodiment 3

[0050] The performance test of shower head material of the present invention:

[0051] Set up a control group, control group 1: do not add aluminum-nickel master alloy, and the rest are the same as in Example 2; control group 2: do not add aluminum-copper master alloy, and the rest are the same as in Example 2; With embodiment 2; The performance parameters of each group are shown in Table 1:

[0052] Table 1

[0053] group

[0054] As shown in Table 1, the present invention improves the mechanical properties, corrosion resistance and high temperature resistance of the alloy material by adding nickel, copper and scandium elements, and greatly prolongs the service life.

Abstract

The invention discloses a novel cooling water tower. The novel cooling water tower comprises a water tower shell; the top of the water tower shell is provided with an air exhaust hole; the upper partof the water tower shell is provided with an inlet pipe, and the inlet pipe is connected with spray headers through branch pipes; the branch pipes and the spray headers are connected in an external cutting angle; one end of each spray header is provided with a horizontal nozzle hole; one end of each spray header provided with each horizontal nozzle hole is in a tapered closing-in shape; the sprayheaders are set in pairs, and the horizontal nozzle holes of each set of the spray headers are arranged oppositely; the bottom of the water tower shell is provided with an inner inclined air inlet plate; the bottom end of the water tower shell is provided with a water collecting bucket, and the bottom end of the water collecting bucket is communicated with a drain pipe . After cooling water entersthe spray headers, the cooling water accelerates inside in a vortex shape, a jetted water column is a fan surface, and a heat exchange area is increased; every two of the spray headers are arranged oppositely, jetted fan-shaped water columns collide with each other, heat exchange efficiency is increased maximumly, water floating rate is low, water consumption is low, and water resource is saved maximumly.

Description

technical field [0001] The invention belongs to the technical field of cooling water towers, and in particular relates to a novel cooling water tower for single-tower and single-fan spraying without filler. Background technique [0002] In the prior art, a cooling water tower is a device for cooling water, in which water exchanges heat and mass with the air flowing through it, resulting in a drop in water temperature. This device is widely used in air-conditioning circulating water systems and industrial circulating water systems middle. The basic principle is: the water to be cooled is sprayed downward through the pipes on the upper part of the water tower, and a large exhaust fan is installed on the top of the water tower to pump the air out of the top of the tower, and the cold air is naturally sucked in from the air inlet at the bottom of the tower to facilitate the flow of air. , The high-temperature water exchanges heat with the low-temperature air to accelerate t...
