Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described further:
Embodiment mono-
As illustrated in fig. 1 and 2, a kind of heat exchanger 5, comprises spiral helicine outer tube 13 and the inner tube 14 that is sleeved on spiral helicine outer tube 13 inside.As shown in Figures 3 and 4, the open at both ends of outer tube 13, one end is that water inlet 8, the other end are delivery port 9, to be connected with outer water tube road, the sealing two ends of inner tube 14, forms the first chamber 17 between outer tube 13 inwalls and inner tube 14 outer walls.In inner tube 14, be set with three tubules 15, and the two ends of tubule 15 are all through inner tube 14 sealing two ends and the first chamber 17 UNICOMs; Between tubule 15 outer walls and inner tube 14 inwalls, form the refrigerant chamber 16 of sealing; The first refrigerant pipe 10 and second refrigerant pipe 11 of UNICOM's refrigerant chamber 16 and space outerpace are set near end positions place in inner tube 14.
In this heat exchanger 5, water is carried by hydraulic pipeline, is entered in the first chamber 17 by one end of outer tube 13.Because 15 first chambers 17 are with tubule 15 intracavity inter-connections, therefore water can fill up the first chamber 17 and tubule 15 inner chambers.After water and cold-producing medium heat exchange, enter hydraulic pipeline from outer tube 13 other ends, and be finally discharged to outside.
Entered in refrigerant chamber 16 by the first refrigerant pipe 10 or the second refrigerant pipe 11 at cold-producing medium, discharge and enter circulation refrigerant pipeline 4 with the refrigerant pipe from the other end after hydrothermal exchange.
In this embodiment, as shown in Fig. 5 (a), inner tube 14 and tubule 15 are tube wall and are concavo-convex contoured metal tube, and the wall thickness of inner tube 14 is 1mm, and external diameter is 1cm.The wall thickness of tubule 15 is 0.5mm, and external diameter is 0.3cm.Outer tube 13 be nickel pipe, aluminum pipe, steel pipe, copper pipe, porcelain tube and flexible metal conduit all can, it does not participate in heat exchange for holding water, therefore without considering the quality of its thermal conduction effect.Employing flexible metal conduit is more corrosion-resistant and pliability is better, need not be processed into spirality, can directly be enclosed within inner tube 14 outer, and plasticity is higher, and cost is lower compared with other material outer tube 13.From the size of inner tube 14 and tubule 15, the heat exchange area increasing after three tubules 15 can increase 90%(3 × 0.3 π ÷ π × 100%=90%).
As shown in Figure 6, a kind of integral air conditioner, comprises cabinet 1 and surface cooler 2, blower fan 3, the compressor 6 of installing in cabinet 1 and the heat exchanger 5 with said structure from top to bottom, comprises in addition the water loop and the refrigerant loop that connect said elements.Between surface cooler 2, cross valve 7, compressor 6 and heat exchanger 5, all connect by refrigerant pipeline 4, between heat exchanger 5 and surface cooler 2, be also provided with check valve 20; Check valve 20 one end by pipeline connect the second refrigerant pipe 11, the other end connects the second capillary 19, the first capillaries 18 and is connected in parallel on check valve 20, thus form can lead refrigerant circulation refrigerant loop.The caliber of the first capillary 18 and the second capillary 19 is all less than the caliber of refrigerant pipeline 4.Outer tube 13 two ends of heat exchanger 5 are connected with outer water tube, and this water pipe is inserted and is embedded in undergroundly, and formation water enters in heat exchanger 5 through outer tube 13 one end, after heat exchange, enters stratum again by outer tube 13 other ends, forms thus circulating water loop.Water flow switch 12 is installed on outer tube 13, current are detected, in the time of water shortage, stop compressor 6 and work, damage in order to avoid cause idle running.
In the present embodiment, cold-producing medium used is freon.
The utility model operation principle and the course of work are as follows:
When refrigeration, cold-producing medium is entered in inner tube 14 by the first refrigerant pipe 10, after heat exchange, is discharged by the second refrigerant pipe 11.The gaseous refrigerant of low-temp low-pressure enters into compressor 6 by refrigerant pipeline 4 by surface cooler 2, and compressor 6, to gaseous refrigerant compressed action, becomes the gaseous refrigerant of HTHP.The cold-producing medium of this state through cross valve 7 enter in the refrigerant chamber 16 of heat exchanger 5 with the first chamber 17 in water carry out heat exchange.After the gaseous refrigerant chance cold water of HTHP, become the liquid refrigerant of low-temp low-pressure, then flow out from the second refrigerant pipe 11, enter the second capillary 19 through check valve 20, after the reducing pressure by regulating flow of the second capillary 19, enter in surface cooler 2 through refrigerant pipeline 4 again.Now, liquid refrigerant and outside air generation heat exchange, and absorb amount of heat in the process of gasification, and lose the air themperature reduction of heat, blow out and form the cold wind that flows by blower fan 3.This process constantly circulates, to reach the object that reduces room temperature.
While heating, cold-producing medium is entered in inner tube 14 by the second refrigerant pipe 11, after heat exchange, is discharged by the first refrigerant pipe 10.The gaseous refrigerant of low-temp low-pressure enters into compressor 6 by refrigerant pipeline 4 by heat exchanger 5, and compressor 6, to gaseous refrigerant compressed action, becomes the gaseous refrigerant of HTHP.The cold-producing medium of this state enters in surface cooler 2 and carries out heat exchange with the external world through cross valve 7, and the gaseous refrigerant of HTHP is met condensation and tied and emit large calorimetric, and after cold air absorbs heat, temperature raises, and is blown out by blower fan 3.Condensed cold-producing medium is through the second capillary 19, then through the first capillary 18 reducing pressure by regulating flows, becomes the liquid refrigerant of low-temp low-pressure.Finally entered in heat exchanger 5 and water generation heat exchange by the second refrigerant pipe 11, absorb the cold-producing medium gasification of heat, then enter refrigerant pipeline 4 by the first refrigerant pipe 10, then enter in compressor 6 through cross valve 7.This process constantly circulates, to reach the object of heating.
Embodiment bis-
Be with embodiment mono-difference, as shown in Fig. 5 (b), the tube wall surface of inner tube 14 and tubule 15 is all jagged, also can increase thus heat exchange area, thereby improves rate of heat exchange.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
