Illustrate the specific embodiment of box-type substation provided by the invention with reference to Fig. 1 to Fig. 5.
As shown in Figure 1, box-type substation provided by the invention includes babinet 1, multiple partition boards, water tank 8 and heat pump system.
Wherein, the internal cavities of babinet 1 are separated into multiple chambers by multiple partition boards, and the quantity of partition board is unlimited, can be according to case Specific change electrical part in body 1 is configured.In a specific embodiment, multiple partition boards include being located at 1 middle part of babinet The internal cavities of babinet 1 are divided into two chambers up and down by diaphragm plate 2 and the vertical clapboard 3 on diaphragm plate 2, diaphragm plate 2, Wherein, lower part is transformation chamber 14, and vertical clapboard 3 continues the cavity on top to be divided into high-pressure chamber 12 and low-pressure chamber 13, the setting of this triangle disposition so that structure is compacter.
Heat pump system includes compressor 4, the first heat exchange structure 5, expansion valve 6 and the second heat exchange structure 7.In partition board and babinet Heat exchanger channels 9 are set in 1 top plate.Second heat exchange structure 7 includes the first heat exchange access and the second heat exchange access, and the first heat exchange is logical Road constitutes the first circulation circuit of the first heat transferring medium, the second heat exchange access, compressor 4, the first heat exchange structure with heat exchanger channels 9 5 and expansion valve 6 constitute the second heat transferring medium second circulation circuit.In this way, in the second heat exchange structure 7, the first heat exchange is situated between Matter transfers heat to the second heat transferring medium, and in the first heat exchange structure 5, the second heat transferring medium transfers heat to water, from And water is heated, used for family or public place, can either so that box-type substation radiates well, but can to waste heat into Row recycling.
In a preferred embodiment, the first heat transferring medium is air, and heat transferring medium is easy to get, cost-effective, and due to the One heat transferring medium is air so that box-type substation is safe and reliable to operation.Second heat transferring medium is by pentafluoropropane and hexamethylene With components by weight percent than 1:Non-azeotropic mixed working medium made of 6.8~7.2, in practice, the non-azeotropic mixed working medium of the component is at this Thermal efficiency height and reliable for operation, inexpensive advantage are had both in invention heat-exchanger rig.The first heat exchange access and heat exchanger channels 9 it Between be provided with air extractor 10, for driving air to be circulated in first circulation circuit, improve heat exchange efficiency, air extractor 10 concrete structure is unlimited, air can be driven to flow, such as air pump, wind turbine etc..
Wherein, heat exchanger channels 9 can be arranged on top plate 11, can also be arranged on partition board, can also top plate 11 and every Plate is respectively provided with heat exchanger channels.It is moved upwards since hot-air density is small, in a preferred embodiment, 9 cloth of heat exchanger channels Full entire top plate 11 and entire diaphragm plate 2, and heat exchanger channels 9 are only arranged in vertical clapboard 3 at an upper portion thereof, so can ensure to change Simplify structure while the thermal efficiency.It is of course also possible to which heat exchanger channels 9 are entirely covered with vertical clapboard 3.
The arrangement of heat exchanger channels 9 is unlimited, in a preferred embodiment, as shown in Fig. 2, heat exchanger channels 9 are in detour Bending structure is made of end to end bow font, the homonymy disengaging of the first heat transferring medium may be implemented.It is preferred at another In embodiment, as shown in figure 3, heat exchanger channels 9 be in double-spiral structure, double-spiral structure include the number of turns it is identical and it is spaced just Helical structure and backpitch structure, right-handed screw structure and backpitch structure cross in center, wherein right-handed screw structure and anti- The number of turns of helical structure is unlimited, can be set according to the size of partition board, it can be achieved that the first heat transferring medium is in very close position Disengaging is set, it is convenient that structure is sealed.Fig. 2 and heat exchanger channels structure shown in Fig. 3 can reach good heat transfer effect.
Further, the transversal direction size towards close to chamber of heat exchanger channels 9 gradually increases, for example, such as Fig. 4 institutes Show, vertical clapboard 3 is formed since its both sides is chamber from centre to both sides size gradually increased structure, then such as Fig. 5 Shown, the lower section of top plate 11 is chamber, therefore forms the gradual increased structure of size from top to bottom, diaphragm plate 2 and 3 class of vertical clapboard Seemingly.Not only guarantee to reach good heat transfer effect in this way, but also can ensure the structural strength of partition board.To reduce gas-flow resistance, It is all made of smooth surface transition in the bending place of heat exchanger channels 9.Preferably, at the full-size of 9 cross section of heat exchanger channels for 5 to 8cm is 2.5 to 4cm at minimum dimension.
Further, it may be simultaneously that the heat exchanger channels 9 of diaphragm plate 2, vertical clapboard 3 and top plate 11, which can be cascaded structure, It is coupled structure, preferably parallel-connection structure.
In a further embodiment, in order to improve heat dissipation effect, as shown in Figure 4 and Figure 5, the conduit wall of heat exchanger channels 9 It protrudes above and is provided with multiple plate protrusions 91, form heat sink so that the indoor heat of chamber is as much as possible to be scattered to heat exchanger channels 9 In.
The specific constructive form of first heat exchange structure 5 and the second heat exchange structure 7 is unlimited, can realize convenient heat exchange i.e. Can, for example, the first heat exchange structure 5 can be plate heat exchanger, shell-and-tube heat exchanger etc., the second heat exchange structure 7 or plate Formula heat exchanger, shell-and-tube heat exchanger etc..
In a further embodiment, water tank 8 can connect nozzle through water valve, be used as shower.
The operational process of the box-type substation is that the hot-air in heat exchanger channels 9 is evacuated to the second heat exchange by air extractor 10 Heat exchange cooling is carried out in structure 7, the air after cooling enters heat exchanger channels 9 and continues to recycle, cold in the second heat exchange structure 7 Matchmaker heat absorption after through expansion valve 6 enter the first heat exchange structure 5, in the first heat exchange structure 5 refrigerant heat release water is heated.
In a further embodiment, box-type substation is set as ground-embedded box type transformer station, and sets heat pump system to Ground-source heat pump system can so improve ground-source heat pump system and be facilitated the placement of Each part, in addition, by case Formula substation, which is embedded in underground, can reduce its occupied space.
The above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention Limitation.
