Abstract
The utility model discloses an evaporative condenser which comprises a condensing coil and a watering device, wherein the condensing coil is provided with a refrigerating agent inlet (9) and a refrigerating agent outlet (10); the watering device is arranged above the condensing coil; and a plurality of pits (11) are uniformly distributed on the peripheral surface of the condensing coil. The plurality of pits (11) which are uniformly distributed on the peripheral surface of the condensing coil are beneficial to the formation and adhesion of a water film on the surface of the condensing coil, so that a contact area between the condensing coil and the water film is increased, and the heat exchange between the condensing coil and the water film is more sufficient, and the heat exchanging effect is better; and due to the condensing coil, the flow resistance of air outside the coil is reduced, the air is taken away with the water while the power dissipation of an outdoor fan is reduced, thereby reducing the heat resistance for the heat exchange, prolonging the time for scaling the copper pipe surface and leading the scales to be difficult to accumulate.
Description
Technical field
The utility model relates to field of heat exchangers, particularly a kind of evaporative condenser.
Background technology
Evaporative condenser is the heat of high-temperature gas cold-producing medium and make the cold-producing medium in the pipe be cooled to liquid state by gaseous state gradually in the absorption coil when utilizing the outer shower water of coil pipe partly to evaporate.Blower fan and air outlet that water pump that the evaporative condenser of prior art comprises the condenser coil that is provided with the cold-producing medium import and export, places the watering device of condenser coil top, the bottom is provided with and water leg and top are provided with.During work, the cooling water in the water leg enters watering device by water pump, and forms the very thin moisture film of one deck by the surface that watering device is sprayed at condenser coil equably.Cold-producing medium enters condenser coil by refrigerant inlet, and after moisture film had absorbed the heat of cold-producing medium, temperature raise and some is evaporated to water vapour, and remainder reenters water leg.Blower fan makes air fast in the condenser coil flows outside, to promote the evaporation of moisture film.The condenser coil of prior art mostly is finned, help conducting heat, but fin is an auxiliary equipment that it is all very inconvenient additionally to assemble, safeguard and clean.And the study of water film distribution that the condenser coil surface forms is inhomogeneous, and heat exchange is insufficient, and the heat exchanging effect has certain influence.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of use simple, as can to make condenser coil surface study of water film distribution more evenly, the evaporative condenser of heat exchange better effects if.
The technical scheme in the invention for solving the above technical problem is: a kind of evaporative condenser, comprise and condenser coil that is provided with refrigerant inlet and refrigerant outlet and the watering device that places the condenser coil top are evenly equipped with several pits on the outer circumference surface of described condenser coil.
Compared with prior art, advantage of the present utility model is: be evenly equipped with several pits on the outer circumference surface of the condenser coil of this evaporative condenser, help moisture film the formation on condenser coil surface with adhere to, increased the contact area of condenser coil and moisture film, make the heat exchange of moisture film and condenser coil more abundant, the heat exchange better effects if; And use this condenser coil to reduce the flow resistance of coil pipe extraneous air, when reducing the outdoor fan power consumption, help air and in time water is taken away, thereby reduce the heat exchange thermal resistance, prolong the fouling time of copper pipe surface, make dirt be difficult to pile up.
As preferably, described pit is circular pit.The radius R of described pit 11 is 2mm≤R≤10mm.Like this, help more moisture film the formation on condenser coil surface with adhere to, the contact area of condenser coil and moisture film is also bigger.
As preferably, described refrigerant inlet places the middle part of a side of described condenser coil, and described refrigerant outlet places the middle part of the opposite side of described condenser coil.Like this, cold-producing medium divides two-way to enter condenser coil, heat exchange more evenly, also more abundant.
As preferably, described condenser coil is made up of first condenser coil and second condenser coil of connection arranged side by side, and described watering device is by placing first watering device and second watering device to form, described first watering device place described first condenser coil directly over, described second watering device place described second condenser coil directly over.Like this, first condenser coil and second condenser coil that connects is combined with first watering device and second watering device respectively side by side, makes cooling coil to contact with water more fully, and heat exchange efficiency is higher.
Description of drawings
The structural representation of Fig. 1 the utility model evaporative condenser.

The A-A sectional structure schematic diagram of Fig. 3 Fig. 2.
Among Fig. 1-3: 1 water pump, 2 first condenser coils, 3 second condenser coils, 4 blower fans, 5, second watering device, 6 first watering devices, 7 installing plates, 8 water legs, 9 refrigerant inlet, 10 refrigerant outlets, 11 pits, the radius of R pit.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As Figure 1-3, a kind of evaporative condenser, the water pump 1 and the blower fan of being located at top and the air outlet that comprise the condenser coil that is provided with refrigerant inlet 9 and refrigerant outlet 10, place watering device, the bottom of condenser coil top to be provided with water leg 8 and to communicate with watering device are evenly equipped with several pits 11 on the outer circumference surface of described condenser coil.
In this specific embodiment, described pit 11 is circular pit.The radius R of described pit 11 is 2mm≤R≤10mm.
In this specific embodiment, described refrigerant inlet 9 places the middle part of a side of described condenser coil, and described refrigerant outlet 10 places the middle part of the opposite side of described condenser coil.Described condenser coil is made up of first condenser coil 2 and second condenser coil 3 of connection arranged side by side, and described watering device is by placing first watering device 6 and second watering device 5 to form, described first watering device 6 place described first condenser coil 2 directly over, described second watering device 5 place described second condenser coil 3 directly over.
During work, cooling waters in the water leg 8 enter first watering device 6 and second watering device 5 respectively by water pump 1, and form the very thin moisture film of one deck by the surface that first watering device 6 and second watering device 5 are sprayed at first condenser coil 2 and second condenser coil 3 equably; Cold-producing medium enters first condenser coil 2 and second condenser coil 3 respectively by refrigerant inlet 9, and temperature raise after moisture film had absorbed the heat of cold-producing medium, and some is evaporated to water vapour, and remainder reenters water leg 8.Blower fan 4 makes air fast in the flows outside of first condenser coil 2 and second condenser coil 3, promotes the evaporation of moisture film.
The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
