Abstract
The utility model relates to a fin type liquid heat exchanger, which comprises a liquid header pipe and a heat exchanger body, wherein the liquid header pipe is provided with a liquid inlet pipe and a liquid outlet pipe; and the heat exchanger body consists of heat exchange tubes which are parallel one another as well as fins and a frame. The fin type liquid heat exchanger is characterized in that the heat exchange tubes are connected in series by a U-shaped elbow and are connected with the liquid header pipe to form a loop; a plurality of loops are arranged in the heat exchanger; a roll booster is arranged inside each heat exchange tube; and two ends of each roll booster are fixed on the inner walls of the heat exchange tubes. The fin type liquid heat exchanger has the advantages that the structure is simple; turbulent flow is added in the heat exchange tubes by the roll boosters so as to increase the heat exchange area and obtain high heat exchange efficiency; and in addition, the volume of the heat exchanger is greatly reduced.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of finned liquid heat-exchanger.
Background technology
Finned heat exchanger is that the realization cold and hot fluid is seen the equipment that heat transmits, in recent years, along with developing rapidly of industries such as China's energy, chemical industry and HVAC, the specification requirement of transmitting for the fluid heat in the industry is also more and more higher, makes to be used for also necessary its performance that improves of finned heat exchanger that fluid thermal is transmitted.At present, widely used heat exchanger mainly is to reach by heat exchange area to increase the purpose that improves heat exchange efficiency in air conditioner industry, thereby heat exchanger volume is big especially.And heat exchanger all is a horizontal positioned usually; and liquid is just stayed the bottom because of deadweight, and during owing to fluid exchange, the heat exchanger tube inner surface area of liquid contact is littler; thereby the heat transfer inner surface of heat exchanger do not have to such an extent that utilize fully, and the heat transfer coefficient of heat exchanger also reduces.In view of above situation, be badly in need of the needs that a kind of novel finned heat exchanger has satisfied high efficient heat exchanging now, improve the performance indications of heat exchanger.
Summary of the invention
The purpose of this utility model has provided a kind of simple in structure, heat exchanger that heat exchange efficiency is high, has solved the deficiencies in the prior art part.
The purpose of this utility model is achieved in that a kind of finned liquid heat-exchanger, comprise: liquid header tube, heat exchanger body, the liquid header tube is provided with feed tube, drain pipe, described heat exchanger body is made up of the heat exchanger tube that is parallel to each other, fin and framework, it is characterized in that: described heat exchanger tube is together in series with U type elbow, be connected with the liquid header tube, form a loop, some described loops are arranged in the heat exchanger, there is a boost motor every heat exchanger tube inside, and the two ends of boost motor are fixed on the inwall of heat exchanger tube.
Described boost motor is a spiral spring.
Described feed tube is provided with draining valve.
Described drain pipe is provided with exhaust-valve.
Described boost motor is fixed with the mode of soldering, uses the soldering bar of silver content 15%.
Described fin and framework are worn string on heat exchanger tube, and the expand tube close-fitting is fixed again.
The utility model has the advantages that: heat exchanger structure is simple, and boost motor increases turbulent flow in heat exchanger tube, improves heat exchange area, and the heat exchange efficiency height reduces heat exchanger volume greatly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the schematic diagram in heat exchanger tube loop in the utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
The specific embodiment
Among Fig. 1 and Fig. 2, a kind of finned liquid heat-exchanger, comprise: liquid header tube 5, heat exchanger body 11, liquid header tube 5 is provided with feed tube 3, drain pipe 4, described heat exchanger body 11 is made up of the heat exchanger tube 7 that is parallel to each other, fin 6 and framework 8, it is characterized in that: described heat exchanger tube 7 usefulness U type elbows 9 are together in series, be connected with liquid header tube 5, form a loop, some described loops are arranged in the heat exchanger, there is a boost motor 10 every heat exchanger tube 7 inside, and the two ends of boost motor 10 are fixed on the inwall of heat exchanger tube 7.
Described boost motor 10 is a spiral spring, and material is stainless steel or other antirust spring.
Described feed tube 3 is provided with draining valve 1.When the liquid coil pipe is stopped using, open the valve draining.
Described drain pipe 4 is provided with exhaust-valve 2.When the liquid coil pipe is stopped using, open the valve steam discharge.
Described boost motor 10 usefulness solderings are fixed on the heat exchanger tube 7 two ends inwalls.The soldering bar of silver content 15% is adopted in copper tube and stainless steel or other antirust spring welding.
Described fin 6 and framework 8 are worn string on heat exchanger tube, and the expand tube close-fitting is fixed again.
Put into identical length size boost motor (spiral spring) in the heat exchanger tube in each loop, then the spiral spring two ends are fixed on the inwall of heat exchanger tube two ends with soldering, again u type elbow is connected on the loop that is in series on the heat exchanger tube, many thin aluminium fins are worn string on smooth copper with the framework end plate at a certain distance, expand tube close-fitting again, with the panel beating frame bracket fixedly heat exchanger tube be connected with fin and install, just constitute the copper pipe aluminum fin convection recuperator, it has into water, two hickeys of water outlet.
During heat exchanger work, liquid enters the liquid header tube, be evenly distributed to again in each loop heat exchanger tube, propelling piece performance action of turbulent flow, liquid is accelerated to flow, and by fin and closely set and air exchange of heat exchanger tube, carries out heat exchange, liquid after exchanging is fully assembled in header concentrated, flows into the liquid back pipe pipeline.
Heat exchanger tube with heat exchange boost motor (spiral spring), along with liquid while exchanging turbulent fluctuation, because density of liquid is heavier, therefore will be evenly distributed in surface in the whole heat exchanger tube along helical trajectory, the heat transfer inner surface of heat exchanger tube is fully utilized, under the situation that does not increase heat exchanger volume, the heat transfer coefficient of heat exchanger is increased.Make the heat exchanger tube inner surface area bigger owing to put into spiral spring in the heat exchanger tube, heat output is increased than the area of the smooth inner wall pipe of same internal diameter.
The utility model has the advantages that: heat exchanger structure is simple, and boost motor increases turbulent flow in heat exchanger tube, improves heat exchange area, and the heat exchange efficiency height reduces heat exchanger volume greatly.
