Abstract

Bubble type water cooling unit comprises air-blast device, water storage device and inlet tube and outlet tube thereof, the filter screen on the water inlet pipe.Bubble is installed in water storage device bloats device, each bubbler that bubble bloats in the device is connected with the pressure appendix, this device is made up of 1-2 layers, every layer 1-20 bubbler, fixedly connected between the bubbler by bracing frame, have the passage of closely arranging and being communicated with in order on the upper surface body of bubbler with its enclosed cavity; And regulate its pressure with pressure regulator.The present invention can be with recirculated water cooling to environment temperature, and energy consumption and cost are low, initial cost is few, volume is little, good cooling results.Not only be used for water circulation cooling, can also be used for the cooling of other liquid.

Description

Bubble type water cooling unit

The invention belongs to water-cooling apparatus.

Existing recirculated water utilizes following two class devices to cool off.The one, heat recirculated water is used in the fountain head that is pumped into cooling tower (or frame) top, water is injected into tiny water droplet, grid along tower flows down, be contained in the blower fan of top of tower or its side, send powerful air-flow, with its suction or blow, form that from bottom to top air flows and from top to down water droplet forms countercurrent flow, evaporation and convection heat transfer' heat-transfer by convection by the spherical convex surface of water droplet make circulating water cooling.This cooling device, equipment is huge, investment and operating cost height, power consumption is big.The 2nd, the fountain cooling device, it is to deliver in the pipe network of arranging the top, cooling pond with pump handle hot water, and water is sprayed from a plurality of nozzles, and it is aerial to form tiny water droplet directive, drops into the pond then again, and this cooling device floor space is big, the operating cost height.

The present invention is directed to above-mentioned the deficiencies in the prior art part, a kind of bubble type water cooling unit is provided, this installs good cooling results, even water temperature can be reduced to below the environment temperature, and energy consumption and cost are low, and volume is little.

By in hot water, blasting a large amount of bubbles.Because the pressure in the effect of surface energy, bubble will be higher than the pressure of corresponding liquid layer, the saturated-steam temperature of liquid raises in the bubble, because bubble lowers the temperature this water layer to the heat transfer that hot water layer's disturbance and water evaporates in bubble.

Lead to bubble with air-blast device by pipe and bloat discharge pressure air in the device, make this air become bubble and overflow, then disturbance and pass the hot water layer and run to airspace.The hot water that need are recycled filters back injection storage device, and air-blast device is installed thereon.Water storage device makes aqua storage tank or tank.It is shaped as bar shaped or garden shape or polygon, and the bubble in its other end and the water storage device bloats that the inner chamber of each bubbler is communicated with in the device.The blast of air-blast device should bloat the pressure of device greater than recirculated water to bubble.Bubble bloats device by the 1-2 layer, form by 1-20 bubbler for every layer, and with water (flow) direction perpendicular or parallel or the two arranged crosswise.Bubble bloats the shape of device and the shape of tank adapts, and the bubble of installing on it to bloat plate parallel with the water surface.Fixedly connected between the bubbler by bracing frame.Bubbler is an enclosed cavity, and its upper surface has the passage of closely arranging and being communicated with cavity in order.Decide on hot water temperature, flow and the blow rate required in the quantity of passage, arrangement and aperture.The top of bubbler is perforate curved body or perforate plane body or the combination of the two.Generally, between the Kong Yukong between the distance be 5-30mm.The aperture is 1-5mm.The by-pass cock of regulating wind pressure is housed on each bubbler.

The present invention compares with existing circulating water cooling device, and having can be with recirculated water cooling to environment temperature, and energy consumption and cost are low, initial cost is few, volume is little, the advantage of good cooling results.Utilize this device can also cool off other liquid, as suspension or emulsion.

Below in conjunction with accompanying drawing the present invention is illustrated:

Embodiment 1

Heat recirculated water is filtered through filter screen [7], enter tank [3] along water inlet pipe [5], the bubble in the tank of packing into bloats enclosed cavity body that bubble that device [4] has a passage by its top bloats plate and its underpart and is fixedly connected and forms.Bubble bloats device and is arranged by water (flow) direction by 5 bubblers, and fixes with bracing frame, and each bubbler transfer port is communicated with an end of appendix, and the other end of appendix is communicated with the blowing mouth of blower fan [1].Blower fan [1] continuously blasts pressure air, enter by gas pipeline in the cavity of each bubbler, the perforate [8] that is bloated on the plate by bubble is overflowed then, make it disturbance hot water intensely, heat in the hot water constantly evaporates in bubble, with the discharge of bubble, heat is dispersed into goes in the atmosphere to make recirculated water cool off, pass through outlet pipe [6] then and flow out.

Embodiment 2

The pressure air that blower fan [1] is sent through the air channel [2] be sent to the garden shape air chest [10] that is arranged in garden shape water storage device [3] central part, deliver to fan-shaped bubble respectively by gas transmission arm [12] thus and bloat in the device [4], and bloat perforate [8] effusion of plate [9] by the bubble of top.When countless bubbles pass the hot water layer, make the water for cooling cooling.Hot water be from water inlet [5] in filter screen [7] flows to annular water tank [11], when liquid level surpasses the height of cannelure inwall, just overflow along inwall, flow in the garden shape water storage device [3], after the bubble cooling, discharge from outlet pipe [6].For garden shape water-cooling apparatus, fan-shaped bubble bloats device can be combined into a garden, the top of each device for a plurality of segments, all there is bubble to bloat plate [9], perforate on it can be arranged or rounded projections arranged by concentric garden, and pitch of holes is 5～30mm, and the aperture is 1～5mm.
