Description
Technical Field
The utility model relates to a heat exchanger field, specific theory relates to an submergence formula evaporative cooling heat exchanger.
Background
Closed cooling towers on the market currently use coiled heat exchangers as heat exchange components. And cooling the outer surface of the coil type heat exchanger by using spray water, and carrying out evaporation by using circulating spray water to take away heat. However, the coil heat exchanger has a small heat exchange surface area, and the space between the coils needs to be enlarged to increase the heat exchange time between the cooling water and the air, so that the whole heat exchanger is bulky. On the other hand, because no medium is arranged between the upper pipe and the lower pipe of the coil pipe to guide the cooling water to flow, when the cooling water descends from top to bottom, the cooling water flows disorderly under the traction of the vertical wind direction, the cooling water easily flies, the water distribution on the coil pipe is uneven, dry spots are easy to exist, the heat exchange capacity is reduced, and scaling risks exist. Therefore, how to increase the heat exchange area of the heat exchanger and improve the heat exchange efficiency becomes the key point of research of people.
Disclosure of Invention
An object of the utility model is to overcome the problem that above-mentioned prior art exists, and provide an submergence formula evaporative cooling heat exchanger. The utility model discloses with the heat exchanger submergence in the pond, adopt direct water-cooling heat transfer, increase heat transfer area improves heat exchange efficiency.
The utility model provides a technical problem adopt following technical scheme:
an immersed evaporative cooling heat exchanger comprises a shell, a heat exchanger, a filler, a water tank, a water pump, a spray pipeline, a spray head, a fan and a working medium; the filler is positioned below the spray header; the fan is positioned above the spray header; the heat exchanger is completely immersed in the water pool; the input end of the water pump is connected with the water outlet at the bottom of the water pool through a spray pipeline, and the output end of the water pump is firstly connected with the spray head through the spray pipeline; the working medium is a gas-liquid two-phase working medium.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, an immersed evaporative cooling heat exchanger comprises a shell 1, a heat exchanger 2, a filler 3, a water tank 4, a water pump 5, a spray pipeline 6, a spray header 7, a fan 8 and a working medium; the filler 3 is positioned below the spray header 7; the fan 8 is positioned above the spray header 7; the heat exchanger 2 is totally immersed in the water pool 4; the input end of the water pump 5 is connected with the water outlet at the bottom of the water pool 4 through a spray pipeline 6, and the output end is connected with a spray head 7 through the spray pipeline 6; a water replenishing ball cock is arranged in the water tank 4; the working medium input port of the heat exchanger 2 is positioned at the upper side, and the working medium output port is positioned at the lower side; the working medium is a gas-liquid two-phase working medium.
The system has three circulations, namely working medium circulation, cooling water circulation and wind circulation. Wherein the working medium circulation loop is: high-temperature or gaseous working medium enters the heat exchanger 2 from the working medium inlet, and is cooled in the heat exchanger 2 and then is changed into low-temperature or liquid working medium to be output from the working medium outlet. The cooling water circulation loop comprises: the low-temperature cooling water in the water pool 4 exchanges heat with the heat exchanger 2 and then is heated to become high-temperature cooling water, the low-temperature cooling water is sprayed into the filler 3 through the spray pipeline 6 and the spray header 7 under the action of the suction force of the water pump 5 to be cooled, and the cooled cooling water continuously exchanges heat with the heat exchanger 2 to carry out next circulation. The wind circulation is as follows: the fan 8 is turned on to cool the filler 3 by air.
The utility model discloses the advantage lies in with 2 submergence of heat exchanger in 4 direct and cooling water heat exchanges, has increased the heat transfer area of heat exchanger 2, has improved heat exchange efficiency.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
