The pond (13) of spray system is positioned at the bottom of U-shaped heating pipe bundle heat exchanger (3), is provided with water inlet pipe (8), overflow pipe (16), water strainer (14), drain pipe (15) etc. in pond (13)。Mine underground shower water passes through water inlet pipe (8), nozzle (12) through condensation segment (5) top that explosion-proof water pump (18) arrives U-shaped heating pipe bundle heat exchanger by standpipe (10) and comb (11) sprays, and nozzle can adopt Y-1 type nylon swirl atomizer。Hot water after spray falls into pond (13), and the overflow pipe (16) in pond can realize the function of automatic overflow。Water in pond is drained by drain pipe (15) after water strainer (14) blowdown。
In this utility model, U-shaped heating pipe bundle heat exchanger used and air cooler all adopt copper pipe light pipe type heat exchanger。
As in figure 2 it is shown, the work process of single U-shaped heat pipe (3-1) is in this utility model: under use state, every single heat pipe inner sealing loop is vacuum filled liquid refrigerant。During loop work, liquid refrigerant collects in evaporator section (3-2), evaporator section (3-2) and mine hot-air to be processed carry out heat exchange, liquid refrigerant in evaporator section (3-2) obtains heat, the refrigerant vapour produced by thermal evaporation arrives condensation segment (3-3) by Connectivity Section (3-4) rising, refrigerant vapour carries out heat exchange with the mine groundwater that sprays through nozzle (12) in spray system in condensation segment (3-3), condensation segment (3-3) refrigerant vapour loses heat, discharge latent heat and condense into liquid refrigerant, liquid refrigerant is under the effect of heat pipe wall surface-wick (3-5) capillary force, return in evaporator section (3-2) through Connectivity Section (3-4), so move in circles operation。Whole work process in heat pipe relies on wick (3-5) capillary force effect, it is not necessary to external energy, just can make cold-producing medium natural circulation。
In this utility model, the work process of spray system is: the water supply of spray system is from mine groundwater, the water supply water temperature of subsoil water requires below 30 DEG C, generally individually can reach requirement, under the power that explosion-proof water pump (9) provides, by mine groundwater by water inlet pipe (8) to erect riser (10), arrive horizontal circular pipes (11) again, by comb (11) upper several nozzles (12), mine groundwater is sprayed at uniformly on the tube wall of condensation segment (5) of U-shaped heating pipe bundle heat exchanger, heat exchange is carried out with the refrigerant vapour in condensation segment (5), owing to spray water temperature is lower than the tube wall temperature of the condensation segment (5) of U-shaped heating pipe bundle heat exchanger, shower water obtains heat, water temperature raises, drop in pond (13) by gravity, pond is filtered the water inlet pipe (8) of reuse feeding spray system again after cooling through water strainer (14), so circulation is endlessly。
In this utility model, the work process of the chilled water of surface-type air cooler is: the freezing water of refrigeration unit produced through water inlet pipe (22) 5～9 DEG C of surface-type air cooler (7) sends into surface-type air cooler, owing to surface-type air cooler (7) tube wall temperature is lower than the temperature of air, surface-type air cooler (7) interior chilled water obtains heat, water temperature raises, chilled water after intensification returns to refrigeration unit through return pipe (23), after carrying out heat exchange with the vaporizer of refrigeration unit, again cool to the freezing water of 5～9 DEG C, enter back into surface-type air cooler (7), so circulation is endlessly。
This utility model mine air processes unit surface-type air cooler (7) and can not work, namely refrigeration unit it is not turned on, do not produce chilled water, only can meet refrigerating capacity by the evaporator section (4) in U-shaped heating pipe bundle heat exchanger, it is achieved that farthest energy-conservation。Embodiment 2 is applicable to the occasion that heat evil is not serious。
It should be noted that the mining air cooling device that this utility model provides according to the needs of actual cooling load, can also adjust the quantity of U-shaped heat pipe。
The above; it it is only preferred embodiment of the present utility model; not this utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation above example made according to this utility model technical spirit, all still falls within the protection domain of technical solutions of the utility model。
