The invention provides a liquid storage device assembly.
In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the liquid reservoir assembly includes a compressor 1, a liquid reservoir 2 and an electronic control unit 3, the electronic control unit 3 includes an electronic control element (not labeled), and the electronic control unit 3 is fixed outside the liquid reservoir 2; the electronic control unit 3 is arranged in a sealing way; the reservoir assembly further includes heat sinks (4a, 4b,4c, 4d) that are in thermal transfer contact with the reservoir 2 for transferring heat generated by the electrical control components to the reservoir 2.
In this embodiment, the liquid reservoir assembly can be applied to common products such as air conditioners, refrigerators and the like, and can also be applied to products which achieve the purpose of heat exchange through refrigerant circulation, such as air energy water heaters. The compressor 1 and the liquid reservoir 2 are used to communicate with a basic unit of a refrigerant circulation system of the liquid reservoir assembly, and it can be understood that the refrigerant circulation system further includes some connecting pipelines, control valves, expansion valves, heat exchangers, and other components, which may be referred to the prior art specifically and are not described herein again.
The compressor 1 and the liquid accumulator 2 are existing components, and the specific functions thereof can be referred to relevant technical data. The compressor 1 sucks low-temperature and low-pressure refrigerant gas from the air suction pipe, drives the piston to compress the refrigerant gas through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The electronic control unit 3 controls the compressor 1 mainly by controlling the electrodes of the compressor 1. The accumulator 2 is connected to a suction pipe of the compressor 1, stores liquid refrigerant, and prevents the liquid refrigerant from flowing into the compressor 1 to generate liquid impact.
The electric control element is mainly an element which generates heat in the process of controlling the compressor 1 and needs to be cooled to ensure normal operation, and as an example, the electric control element may include: IPM (Intelligent Power Module), i.e., an Intelligent Power Module, a motor drive inverter, and a PFC (Power factor correction device).
The electric control unit 3 can be sealed by adopting an insulating material to wrap the whole electric control unit 3 so as to isolate the electric control unit 3 from air; it is also possible to place the electronic control unit 3 in a closed space, for example in a closed box. The degree of sealing is sufficient to prevent the generation of condensed water.
The heat sink (4 a,4b,4c,4 d) is usually made of a material having excellent heat conductivity, and the shape thereof is not particularly limited, but the heat contact area between the heat sink (4 a,4b,4c,4 d) and the reservoir 2 is ensured.
Heat dissipation between the heat dissipation member (4 a,4b,4c,4 d) and the electric control element can be performed by adopting a traditional air convection mode, and can also be performed by adopting a heat dissipation member (4 a,4b,4c,4 d) to be contacted with the electric control element and performing heat dissipation in a heat transfer contact mode. When the heat dissipation is performed by adopting the air convection mode, a heat dissipation fan can be additionally adopted to strengthen the air convection.
According to the liquid storage device assembly, the heat dissipation is carried out on the electric control unit 3 through the heat dissipation pieces (4a, 4b,4c and 4d), and the electric control unit 3 is arranged in a sealing manner, so that even if the temperature of the electric control unit 3 reaches a dew point, the generated condensed water cannot invade the electric control element, the original insulating property of the electric control unit 3 is not influenced, and the working reliability is high.
In some specific examples of the present invention, referring to fig. 3 to 5 together, the liquid reservoir assembly further includes a box 5, the electronic control element is disposed in the box 5, a window 511 is formed in one side of the box 5 facing the liquid reservoir 2, the window 511 is engaged with the heat sink (4 a,4b,4c,4 d) to seal the electronic control unit 3, and the heat sink (4 a,4b,4c,4 d) receives heat generated by the electronic control element through the window 511.
In this embodiment, by providing the electric control element inside the box 5, it is a relatively simple way of isolating the electric control element from the external space, and it is easier to implement from an assembly point of view. The box body 5 is provided with a window 511, so that the heat dissipation members (4a, 4b,4c and 4d) can receive the heat generated by the electric control element conveniently. The sealing engagement between the window 511 and the heat sink (4a, 4b,4c, 4d) may be by welding, glue bonding or seal attachment or simple mechanical attachment.
In some specific examples of the invention, the reservoir assembly further comprises a sealing ring (6a, 6b, 6c), and the window 511 is in sealing fit with the heat dissipation member (4a, 4b,4c, 4d) through the sealing ring (6a, 6b, 6c). The box body 5 and the heat radiating pieces (4a, 4b,4c, 4d) can be kept well sealed in the vibrating environment by arranging the sealing rings (6a, 6b, 6c); in addition, the assembly of the cartridge 5 with the heat sink (4a, 4b,4c, 4d) is also facilitated.
In some embodiments of the present invention, referring to fig. 6 and 7, in the first embodiment of the present invention, the edge portion of the window 511 has an outer mating surface 511a facing the liquid reservoir 2, the heat sink 4a has a first mating surface 41a opposite to the outer mating surface 511a, and the sealing ring 6a is disposed between the outer mating surface 511a and the first mating surface 41 a.
In this embodiment, the packing 6a and the case 5 may be assembled to the liquid reservoir 2 in this order. In some embodiments, the outer engagement surface 511a of the box 5 and the first engagement surface 41a together maintain a preload on the sealing ring 6a, so as to keep the electronic control unit 3 isolated from the air outside the box 5 in a vibrating environment.
In some embodiments of the present invention, referring to fig. 8 and 9, in the second embodiment of the present invention, the edge portion of the window 511 has an inner mating surface 511b facing away from the liquid reservoir 2, the liquid reservoir assembly further includes a bracket 7b disposed in the box body 5, the bracket 7b has a pressing surface 71b opposite to the inner mating surface 511b; the seal ring 6b has a seal groove 61b into which an edge portion of the window 511 is fitted, the seal groove 61b has a first side wall 62b and a second side wall 63b which are opposed to each other, the first side wall 62b is located between the outer engagement surface 511a and the first engagement surface 41b, and the second side wall 63b is located between the inner engagement surface 511b and the press contact surface 71 b.
In the present embodiment, the seal ring 6b is engaged with the edge portion of the window 511 through the seal groove 61b, so that the seal ring 6b can be fitted to the case 5 in advance at the time of fitting. Moreover, the sealing ring 6b can realize two-layer sealing through the first side wall 62b and the second side wall 63b, so that a better beneficial effect is achieved.
In a further embodiment in which the heat sink 4b includes a base plate attached to the reservoir 2 and a projection provided on a surface of the base plate 41 facing away from the reservoir 2, a third layer of seal may be formed by fitting an inner wall surface of the seal ring 6b to an outer peripheral surface of the projection 42.
In some embodiments of the present invention, referring to fig. 10 and 11, in a third embodiment of the present invention, the edge portion of the window 511 has an inner mating surface 511b facing away from the liquid reservoir 2; the liquid reservoir module further includes a holder 7c provided in the case 5, the holder 7c having a press-contact surface 71c opposed to the inner engagement surface 511b; the heat sink 4c has a second mating face 42c opposed to the press contact face 71c; the seal ring 6c covers the inner engagement surface 511b and the second engagement surface 42c, and is located between the press contact surface 71c and the inner engagement surface 511 b.
In this embodiment, by pressing the gasket 6c with the bracket 7c in a direction toward the heat sink 4c, it is possible to maintain the sealing engagement between the cartridge 5 and the heat sink 4c and fix the cartridge 5 to the heat sink 4c or the liquid reservoir 2. In a further embodiment where the heat sink 4c includes a substrate attached to the liquid reservoir 2 and a protrusion disposed on a surface of the substrate 41 facing away from the liquid reservoir 2, the first mating surface 41c is formed on the substrate, the second mating surface 42c is formed on the protrusion, an edge of the window 511 further abuts against the substrate, and an inner circumferential surface of the opening 72c of the bracket 7c cooperates with an outer circumferential surface of the protrusion to perform both a function of limiting the bracket 7c and a function of sealing.
In some specific examples of the present invention, the heat sink (4a, 4b,4c, 4d) includes a base plate 41 attached to the reservoir 2 and a protrusion 42 provided on a surface of the base plate 41 facing away from the reservoir 2, and the bracket (7a, 7b,7c, 7d) has an opening (72a, 72b,72c, 72d) provided corresponding to the protrusion 42, and an inner circumferential surface of the opening (72a, 72b,72c, 72d) is fitted to an outer circumferential surface of the protrusion 42. In this embodiment, the inner circumferential surface of the opening (72a, 7b,7c, 7d) of the bracket (7a, 7b,7c, 7d) and the outer circumferential surface of the projection 42 are engaged to serve both as a stopper for the bracket (7a, 7b,7c, 7d) and to prevent the bracket (7a, 7b,7c, 7d) from being dislocated relative to the heat sink (4a, 4b,4c, 4d).
In some specific examples of the present invention, the electric control element includes a power control module 311, the bracket (7a, 7b,7c, 7d) is provided with a position limiting hole (73a, 73b,73c, 73d) opened toward the heat radiating member (4a, 4b,4c, 4d), and the position limiting hole (73a, 73b,73c, 73d) is position-limit-fitted with the power control module 311. The heat sink (4a, 4b,4c, 4d) is in heat-transferring contact with the power control module 311 via the window 511.
In the present embodiment, the heat-dissipating member (4a, 4b,4c, 4d) is in heat-transfer contact with the reservoir 2 and the power control module 311 at the same time, so that the heat-dissipating effect of the power control module 311 is higher. The power control module 311, such as IPM, generally consumes higher power and generates relatively higher heat than other electronic control components, so that the power control module 311 is in heat transfer contact with the heat dissipation member (4a, 4b,4c, 4d), which is beneficial to providing better heat dissipation conditions for the power control module 311, and the heat dissipation arrangement is more reasonable, thereby ensuring that the electronic control unit 3 as a whole can be effectively dissipated.
In some embodiments, the electronic control unit 3 further includes a circuit board 32, and by mounting the power control module 311 on the circuit board 32, heat generated by the power control module 311 can be transferred to the circuit board 32 and can be dissipated through the circuit board 32. Or the heat generated by the circuit board 32 can be transferred to the liquid reservoir 2 through the heat dissipation members (4a, 4b,4c, 4d) to achieve the purpose of heat dissipation. It will be appreciated that circuit board 32 can integrate the basic circuit connections and provide support for power control module 311 mounted thereon and facilitate electrical connection of power control module 311 to other electronic control components
It will be understood that since the compressor 1 is vibrated during operation, and the accumulator 2 is fixedly connected to the compressor 1, the electronic control unit 3 is forced to vibrate when a vibration transmission path exists between the electronic control unit 3 and the accumulator 2 and/or between the electronic control unit 3 and the compressor 1. For example, the vibration of the reservoir 2 may be transmitted to the electronic control unit 3 through the heat sink (4a, 4b,4c, 4d), the power control module 311, and the circuit board 32. By providing the limit holes (73a, 73b, 7c, 7d) in the holder (7a, 7b,7c, 7d) to limit the power control module 311, it is possible to prevent the power control module 311 from being displaced relative to the circuit board 32 in such a vibration environment, thereby causing an operation failure. It is understood that the bracket (7a, 7b,7c, 7d) and the heat sink (4a, 4b,4c, 4d) may be fixedly connected by fastening members such as screws, bolts, or may be fixedly connected by welding or gluing. In some specific examples of the present invention, the bracket (7a, 7b,7c, 7d) is fixedly attached to the circuit board 32 in addition to the heat sink (4a, 4b,4c, 4d).
In some embodiments, the electronic control element further comprises a capacitor 312 and an inductor 313. In the electronic control elements of the electronic control unit 3, the heat generated by the capacitor 312 and the electronic control is usually much smaller than that generated by the power control module 311, and nevertheless, the capacitor 312 and the inductor 313 still need to be dissipated to ensure normal operation. In some embodiments, the capacitor 312 and the inductor 313 are disposed on a side of the circuit board 32 facing the liquid reservoir 2, so that heat generated by the capacitor 312 and the inductor 313 can be radiated to the liquid reservoir 2 more quickly, and thus heat can be dissipated more efficiently. In order to facilitate heat dissipation of capacitor 312, an insulating heat dissipation rubber pad may be disposed between the outer wall surface of capacitor 312 and the inner wall surface of case 5.
In some embodiments of the present invention, referring to fig. 12 and 13, in a fourth embodiment of the present invention, the liquid reservoir assembly further includes a bracket 7d disposed in the box body 5 and abutting against a connection portion of the heat sink 4d and the edge of the window 511; the matching surfaces of the bracket 7d and the box body 5 and the matching surfaces of the bracket 7d and the heat sink 4d are bent and extended.
In this embodiment, the heat dissipation member 4d and the case 5 can be sealed only by mechanical cooperation between the bracket 7d and the case 5 and between the bracket 7d and the heat dissipation member 4d, and the structure is simple.
Specifically, as an example, a rim portion of the window 511 has an inner mating face 511b facing away from the liquid reservoir 2;
the inner wall surface of the case body 5 includes annular first step surface 513 and second step surface 514, and the first step surface 513 is connected between the inner mating surface 511b and the second step surface 514;

the recess 423 has a third step surface 424 contiguous with the inner mating surface 511b, and a fourth step surface 425 connecting between the third step surface 424 and the front surface 421;
the holder 7d and the holder 7d have press-contact surfaces 71d that engage with the inner engagement surface 511b and the third step surface 424, a first recess 74d that fits with the first step surface 513 and the second step surface 514 is formed on the outer peripheral surface of the holder 7d, and a second recess 75d that fits with the fourth step surface 425 and the front surface 421 is formed on the inner peripheral surface of the holder 7 d.

In this embodiment, since the box body 5 is formed by combining the box body 51 and the box cover 52 which are separated, the electronic control unit 3 can be assembled into the box body 51 through the mounting opening 512, and then the box cover 52 is sealed and combined with the mounting opening 512. The sealing between the box cover 52 and the box body 51 can be performed by welding, glue bonding, sealing element connection or mechanical sealing and fitting. In some embodiments, the seal between the lid 52 and the body 51 is facilitated. The box cover 52 is provided with an annular groove 521 adapted to the edge of the mounting opening 512. Specifically, the window 511 is opened on a bottom wall of the box body 51 opposite to the box cover 52, and the box cover 52 is detachably fitted to the mounting opening 512 of the box body 51.
