Abstract
The utility model relates to a heat exchanger with a refrigerator. The utility model is characterized in that the heat exchanger in prior art is connected with the refrigerator through a pipe line. The refrigerated water generated by the is used as the cold fluid of the heat exchanger to improve the temperature difference of the cold fluid and the hot fluid and improve the heat exchange quantity or reduce the volume of the heat exchanger in a finite heat exchange quantity. The utility model is suitable for use in the occasion with limited occupation space and high cold fluid temperature, such as the air cooling device of a generator, etc. The utility model has the advantages of small heat exchanger volume, large heat exchange quantity and simple technology.
Description
The utility model relates to the heat exchanger that has refrigeration machine, belongs to heat transmission equipment.Be particularly useful for institutes such as the generator air cooler occasion limited and that cooling fluid temperature is high that takes up space.
The dividing wall type heat exchanger of prior art is that cold and hot fluid is spaced, and hot fluid with the heat transferred cold fluid, reaches the purpose of heat exchange by heat-transfer surface.Its formation comprises parts such as heat-exchanging tube bundle, cold fluid entrance and exit, hot fluid entrance and exit.By the tube side and the shell side of heat-exchanging tube bundle, cold fluid generally adopts temperature to be lower than the cooling water of hot fluid to cold and hot fluid respectively.As everyone knows, the heat output of heat exchanger is decided by the heat transfer area of heat-exchanging tube bundle, the temperature difference and the heat transfer coefficient of cold fluid and hot fluid.The heat exchanger of current technology is adopting under high thermal conductivity and the rational economically material, designed the heat-exchanging tube bundle of various planforms such as fin, or the employing flow velocity is high as far as possible, temperature is tried one's best low cold fluid, with the control heat exchanger volume.
The weak point of prior art heat exchanger is that the measure of above-mentioned its volume of control all is limited, for the big occasion of need heat exchange amount, gets only the huge heat exchanger of design volume.But limited in some occasion for the space that heat exchanger is set, for example, for the air cooler of generator closed circulation, because of being subjected to the restriction of duct space, can not the very big air cooler of design volume.Therefore, require to design under certain heat exchange amount the important topic that the small size heat exchanger remains design of heat exchanger.
The purpose of this utility model is intended to overcome the deficiencies in the prior art and a kind of heat exchanger that has refrigeration machine of designing.Because by the process conditions decision, thereby the technical solution of the utility model is to reduce the temperature of cold fluid, to improve the temperature difference of cold and hot fluid, makes under certain heat exchanger volume, improves the heat exchange amount as the hot fluid temperature of heat exchange object.Measure is the configuration refrigeration machine, and the chilled water that produces with refrigeration machine is as the cold fluid of heat exchanger.
The technical solution of the utility model is achieved in that sees accompanying drawing 1.(9) be the heat-exchanging tube bundle of heat exchanger (8), (7) are the hot fluid inlets of heat exchanger (8), and (13) are the hot fluid outlets of heat exchanger (8), and (12) are the cold fluid inlets of heat exchanger (8), and (10) are the cold fluid outlets of heat exchanger (8).Cold fluid inlet (12) installing pipeline at heat exchanger (8) is connected with the chilled water outlet (3) of refrigeration machine (1) through Pressure gauge (6), thermometer (5), valve (4).Cold fluid outlet (10) installing pipeline at heat exchanger (8) is connected with the water inlet (16) of water tank (17) through valve (11), thermometer (14), Pressure gauge (15).Delivery port (18) in water tank (17) is connected with the chilled water inlet (20) of refrigeration machine (1) through water pump (19) by pipeline.
The hot fluid of the utility model heat exchanger can be gas or liquid, and cold fluid is a chilled water; Refrigeration machine can be a lithium bromide refrigerator, also can be freon refrigeration machine or ammonia machine.
Such design has improved the heat exchange amount, and the temperature of hot fluid is obviously descended, and also can dwindle heat exchanger volume; Technology is simple, effect is remarkable, economic benefit is high.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the heat exchanger that has refrigeration machine;
Fig. 2 is the air cooler that has refrigeration machine.
Below in conjunction with embodiment the utility model is done further statement:
Embodiment 1
Fig. 2 is the air cooler that present embodiment has refrigeration machine.It is made up of air cooler (26), refrigeration machine (1), water tank (17) and water pump (19) etc.(25) be the heat-exchanging tube bundle of air cooler (26), hot blast as hot fluid flows through heat exchange between heat-exchanging tube bundle (25), (24) be air cooler (26) chilled water inlet and go into hydroecium, (28) are the chilled water outlet and the water-supplying chamber of air cooler (26), (27) are the collecting chambers of air cooler (26).Chilled water inlet (24) installing pipeline in air cooler (26) is connected with the chilled water outlet (3) of refrigeration machine (1) by Pressure gauge (6), thermometer (5), butterfly valve (4).Chilled water outlet (28) installing pipeline in air cooler (26) is connected with the water inlet (16) of water tank (17) through butterfly valve (11), thermometer (14), Pressure gauge (15).Delivery port (18) in water tank (17) is connected with the chilled water inlet (20) of refrigeration machine (1) through water pump (19).The refrigeration machine of present embodiment (1) adopts the absorption lithium bromide refrigerator of steam double-effect, and among Fig. 2, (21) are the lithium bromide refrigerator cooling water inlets, and (2) are its outlets, and (23) are the lithium bromide refrigerator steam inlets, and (22) are the steam condensate outlets.
The air cooler of present embodiment is used in the closed circulation air cooling system of two 12MW steam turbine generators, and effect is fine.Especially summer, the natural temperature degree from the rivers and lakes as cold fluid is very high, when causing generator to have under underload, move, adopt the air cooler of present embodiment, control enters the chilled water temperature and the pressure of air cooler, generator can be a little more than rated load operation, and economic benefit is fine.
Fig. 1 is the heat exchanger that present embodiment has refrigeration machine, and hot fluid is a lubricating oil, claims oil cooler.Be used in the cooling system of Steam Turbine lubricating oil, effect is fine equally.
