The utility model discloses a U type heat exchange tube, the time only need weld one end in the welding, pass through the elbow welding together with the head of heat exchange tube, and the inside heat exchange tube of conventional heat exchanger be the straight tube, both ends all need be welded during the welding, work efficiency reduces, moreover the heat transfer efficiency reduction of the performance of heat exchange tube.
Description
Technical field
The utility model relates to a kind of heat exchanger, and what be specifically related to is a kind of finned type heat exchanger including U heat exchange.
Background technology
Heat exchanger, be the equipment partial heat of hot fluid being passed to cold fluid, heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial department, occupies critical role aborning.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies very more extensive.All condenser is housed in existing air-conditioner, when air-conditioner is operated in refrigeration mode, compressor in air-conditioner by the road and reversal valve HTHP refrigerant is input in condenser, HTHP refrigerant is stuck up by the pipeline of condenser and the heat radiation be arranged on pipeline and carries out cold and hot exchange with the air in the external world, refrigerant temperature after cold and hot exchange will reduce significantly, refrigerant after cooling flows into expansion valve by the road, evaporimeter, refrigerant is by rapid spatial expansion after expansion valve, the heat in air is absorbed by evaporimeter when refrigerant after expansion flows through evaporimeter by the road, the refrigerant absorbed after heat flow back in compressor by the road again.When air-conditioner is operated in heating mode, the commutation through reversal valve makes above-mentioned cyclic process just in time contrary, and this up-to-date style condenser will absorb heat from outside air, and evaporimeter will to release heat in room air.The condenser of idle call is essentially finned type heat exchanger, and thermal grease is the Heat Conduction Material of a low thermal resistance and high thermal conductivity, high flexibility.The high flexibility that this material has can reduce pressure required between components and parts, covers the irregular surface of microcosmic simultaneously thus makes components and parts fully contact and improve heat conduction efficiency.If thermal grease is applied to the exchange efficiency that the low place of heat exchanger exchange efficiency can strengthen heat exchanger greatly.
In commercialization heating, ventilation and air handling system, finned type heat exchanger used adopts circular heat exchanger tube usually, in these application scenarios, according to the difference of service condition, adopt the heat exchanger tube of different row, air is easy to when flowing through circular heat exchanger tube form eddy current, thus causes air drag to increase and heat exchange performance variation.
Patent CN201364066Y discloses a kind of finned heat exchanger, and the heat exchanger tube of proposition is oval straight tube, and before elliptical tube solves, the heat exchange performance of straight tube is poor, but straight tube in use, two ends all need welding, and not only length consuming time, more serious still causes unstable properties.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of finned type heat exchanger including U heat exchange, improves operating efficiency, but also improves the performance of heat exchanger.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of finned type heat exchanger including U heat exchange, comprise heat exchanger tube and heat exchange fin, described heat exchanger tube is arranged in described heat exchange fin, described heat exchanger tube is U heat exchange, connected by elbow between two ports of described U heat exchange, described elbow and described heat exchanger tube are by being welded into one.
As what optimize, described heat exchange fin is the aluminium material matter of chip of putting in a skylight.
As what optimize, the diameter of described heat exchanger tube is consistent with the diameter of described elbow.
As what optimize, described heat exchanger tube is oblate pipe or elliptical tube, is inside provided with temperature-sensing pipe.
As what optimize, described heat exchanger tube and described elbow are interior threaded copper pipe.
The beneficial effects of the utility model are:
The U heat exchange that the utility model adopts, only need weld one end when welding, by the head of heat exchange by elbow welding together, and the heat exchanger tube of the heat exchanger inside of routine is straight tube, during welding, two ends all need welding, and operating efficiency reduces, and the heat transfer efficiency of the performance of heat exchanger tube reduces.
U heat exchange tube bank can free-extension, and can not produce thermal stress because of the temperature difference between shell, thermal compensation performance is good; Tube side is two-tube-pass, long flow path, and flow velocity is high, good heat-transfer, and bearing capacity is strong, improves the performance of heat exchanger.
