Description

Heat exchange equipment and air conditioner

Technical Field

The invention relates to a heat exchange device and an air conditioner.

Background

The electric cabinet part of the heat exchange device is generally composed of a sheet metal part, and a printed circuit board (PRINTED CIRCUIT BOARD, abbreviated as PCB) is arranged on the side wall of the sheet metal part. Fig. 1 is a schematic view of an installation structure inside an electric cabinet in a conventional heat exchange device. In fig. 1, the sheet metal part forms an electric cabinet side plate a4, which is fixedly connected with a heat exchanger a1 in the heat exchange device. The PCB 3 is arranged on a side plate a4 of the electric cabinet far away from the heat exchanger a 1. A compressor a2 is also arranged in the space surrounded by the electric cabinet side plate a 4.

When the sheet metal part is bent, the electric cabinet side plate a4 is easy to rebound, so that the machining precision is not high. When sheet metal component carries out the assembly with heat exchanger a1 among the heat exchange device, still need carry out secondary operation to heat exchanger a1, lead to the installation very loaded down with trivial details, increase processing cost. On the other hand, the sheet metal part is not easy to directly process the radiating fins, and if the PCB a3 installed on the electric cabinet side plate a4 has a large heating value, the radiating is difficult. If the heat dissipation problem is to be solved under this structure, additional heat sinks are required, which also results in increased costs.

Detailed Description

The technical scheme of the invention is further described in detail through the drawings and the embodiments.

Fig. 2 is a schematic structural view of an embodiment of the heat exchange device of the present invention. Referring to fig. 3 to 7, the heat exchange apparatus of the present embodiment includes: a heat exchanger 1 and an electric cabinet 2. The electric cabinet 2 is arranged at one side of the heat exchanger 1, and a cavity for accommodating electric control components is formed. The shell of the heat exchanger 1 and the electric cabinet 2 are integrally formed.

In this embodiment, because the shell of the heat exchanger and the electric cabinet adopt an integrally formed processing mode, the process of performing secondary processing on the shell of the heat exchanger to realize assembly with the electric cabinet is omitted, so that the installation process of the heat exchange device is simpler, the assembly efficiency is improved, and the processing cost is reduced.

Referring to fig. 2, in some embodiments, the heat exchanger 1 may be a condenser or an evaporator or the like. While the housing of the heat exchanger 1 may comprise: a heat exchange chamber side wall 11, a heat exchange tube body 13 and a plurality of fins 12. Wherein the heat exchange chamber side walls 11 extend in the up-down direction and form a heat exchange chamber. The heat exchange pipe body 13 includes a plurality of straight pipe sections disposed in the heat exchange chamber and extending in parallel in the up-down direction. The straight pipe sections can be further communicated through a connecting pipe 14. Fins 12 are provided in the heat exchange chamber and extend in the up-down direction, and the fins 12 are connected between different straight tube sections or between the straight tube sections and the heat exchange chamber side walls 11.

In fig. 2, the heat exchange chamber side wall 11, the heat exchange tube body 13 and the plurality of fins 12 may form a housing of the heat exchanger 1 in an integrally formed manner, and perform a heat exchange function as a main structure. Compared with the existing heat exchanger with the multilayer aluminum fins and the copper tubes in interference fit with the aluminum fins, the heat exchange tube and fins are not required to be assembled, and the combined structure of the heat exchange tube and the fins and the combined process of the heat exchange tube and the side wall of the heat exchange chamber are not required, so that the manufacturing and assembling process can be simplified, the processing efficiency can be improved, and meanwhile, the processing cost can be reduced. And by combining the electric cabinet and the shell of the heat exchanger 1 into a whole, the assembly efficiency can be further improved, and the processing cost can be reduced.

The shell of the heat exchanger 1 and the electric cabinet 2 are preferably integrally formed by extrusion. Because the integral forming process can control the machining forming precision through the extrusion die, the machining precision of the formed part obtained after machining is higher than that of the electric cabinet side plate adopting the sheet metal part in the prior art. In other embodiments, the housing of the heat exchanger 1 and the electric cabinet 2 may be formed integrally, such as by casting or forging.

Still referring to fig. 2, in some embodiments, the electric cabinet 2 includes at least one side plate, such as side plates 21 and 22 located on the upper and lower sides (i.e., left and right sides in fig. 3) in fig. 2. The side plates may enclose a chamber with the heat exchanger 1 with lateral openings. Fig. 3 shows the internal structure of the electric cabinet as seen from the lateral opening towards the inside of the chamber. Since the chamber is provided with side plates 21 and 22 on both sides, respectively, the cross section of the chamber is in a "C" shape and is open in the up-down direction. This cross-sectional shape increases the operating space inside the electric cabinet 2 and allows personnel to handle the components inside the electric cabinet 2 from the lateral opening or the upper or lower end of the chamber.

In order to isolate the components within the chamber of the electric cabinet 2 from the outside after assembly, referring to fig. 2 and 7, the heat exchange apparatus in some embodiments further comprises a door panel 51. The door panel 51 is detachably arranged at the lateral opening for closing the chamber. After the operator has completed the installation of the components inside the chamber of the electric cabinet 2, the door panel 51 may be installed in the lateral opening by screws or other connectors. When the staff needs to disassemble or repair the internal components of the electric cabinet 2, the door plate 51 can be disassembled from the electric cabinet 2 first, so that a larger operation space is obtained from the lateral opening, and the disassembling or repairing process is simpler and more convenient. The contour shape and dimensions of the door panel 51 may be matched to the contour shape and dimensions of the lateral opening in order to ensure the closing effect of the door panel 51. In other embodiments, a single side panel may be provided and the door panel may close the lateral opening formed between the single side panel and the heat exchanger.

In the prior art, an additional radiator is required to be additionally arranged to radiate heat for some components which generate a lot of heat in the PCB during operation, so that the cost is increased. Thus, referring to fig. 2 and 3, in some embodiments of the heat exchange device of the present invention, the outer side surfaces of the side plates 21 and 22 are provided with the first heat radiating fins 24. The first heat dissipation fins 24 can be integrally formed with the side plates (for example, extrusion and integral forming), so compared with the limitation that the sheet metal part serving as the side plate of the electric cabinet in the prior art cannot be directly processed into the heat dissipation fins, the heat dissipation area of the side plates 21 and 22 can be effectively increased by the first heat dissipation fins 24 in the embodiment, so that the heat inside the electric cabinet 2 can be more rapidly dissipated outwards. Compared with the prior art, the first radiating fins can be integrally formed on the side plates, so that an additional radiator is not required, and the cost is reduced.

Inside the electric cabinet 2, first PCB boards 31 and 32 may be further included. Referring to fig. 2 and 3, the first PCB boards 31 and 32 are disposed on inner side surfaces of the side plates 21 and 22, respectively, for carrying electrical control components. The first PCB is arranged on the inner side surface of the side plate of the electric cabinet, and heat dissipation and cooling of the PCB can be realized by utilizing heat exchange outside the side plate. In addition, the first PCB boards 31 and 32 provided at the side plates 21 and 22 may also arrange direct routing in the space between the side plates 21 and 22, thereby facilitating routing. In the embodiment of integrally forming the side plate and the first radiating fin, the heat dissipation capacity of the side plate is stronger, so that the first PCB arranged on the inner side surface of the side plate can better dissipate heat and cool so that the borne electrical control components can keep a proper working temperature.

Referring to fig. 2 and 7, in some embodiments, a second heat radiating fin 52 may be further provided at an outer side surface of the door panel 51, and the second heat radiating fin 52 is formed by being integrally formed (e.g., extrusion-integrally formed) with the door panel 51. The second heat dissipation fins provided on the door plate 51 can effectively increase the heat dissipation area of the door plate 51, so as to promote the heat inside the electric cabinet 2 to be dissipated outwards more rapidly.

In order to more stably provide the first PCB boards 31 and 32 at the inner side surfaces of the side plates 21 and 22, referring to fig. 2 to 6, first mounting frames 41 and 42 may be provided in the chamber inside the electric cabinet 2. First mounting brackets 41 and 42 are provided on the inner side surfaces of the side plates 21 and 22, respectively, and the first printed circuit boards 31 and 32 are mounted on the first mounting brackets 41 and 42, respectively. The number of the first mounting frames may be determined according to the number of the first PCB boards or the number of the side plates. Each first mounting plate may be made identical in shape and structure, thereby enabling versatility.

Fig. 5 and 6 show a structural example of the first mounting bracket. Referring to fig. 6, the first mounting frame is provided with a recess structure 4e recessed toward the inside of the cavity, and a through hole 4a for mounting the first PCB board is provided at the bottom of the recess structure 4 e. The first PCB board may pass through the through hole 4a and the side plate to be close to the side plate, or cling to the side plate to further improve the heat dissipation effect of the first PCB board, and the concave structure 4e may support the first PCB board at a position closer to the inner side of the cavity. The concave structure 4e may be formed by the upper bent portion 4b and the lower bent portion 4c of the first mounting bracket in fig. 5 together. When the upper bending portion 4b and the lower bending portion 4c are connected to the inner side surface of the side plate through the connecting members, the portion between the upper bending portion 4b and the lower bending portion 4c encloses a region with the side plate where the first PCB board can be stably mounted.

In addition to the possibility of mounting the first printed circuit board on the side panel, referring to fig. 2-4, in still other embodiments, a second mounting bracket 43 and a second PCB 33 are included, the second mounting bracket 43 being disposed between each of the first mounting brackets (e.g., between the first mounting brackets 41 and 42). The second PCB 33 is disposed on the upper surface of the second mounting frame 43, so that the number of PCB boards that can be disposed in the cavity of the electric cabinet 2 is increased, and the second PCB 33 and the first PCBs 31 and 32 can be directly routed in the space between the side plates 21 and 22 and the second mounting frame 43, thereby facilitating the routing.

In order to make the connection of the second mounting frame 43 within the chamber more stable, an inwardly extending support portion 4d may be provided at the lower ends of the first mounting frames 41 and 42 for supporting the second mounting frame 43, and the support portion 4d may be connected with the second mounting frame 43 through a connection member while supporting the second mounting frame 43. The first mounting frame and the second mounting frame can be sheet metal parts, and the bending part and the supporting part of the first mounting frame can be formed through sheet metal technology.

The second mounting frame 43 may divide the chamber of the electric cabinet 2 into at least two sub-chambers in the up-down direction. For example, the upper and lower sub-chambers of the second mounting frame 43 shown in fig. 2, wherein the upper sub-chamber is provided with the first printed circuit boards 31, 32 and the second printed circuit board 33, and the lower sub-chamber is provided with the compressor 6. That is, the chamber of the electric cabinet 2 is also used to accommodate the compressor 6, and the compressor 6 is disposed in different sub-chambers with the first printed circuit boards 31, 32 and the second printed circuit board 33, respectively. The number of the second mounting frames 43 is not limited to one, and the provision of more second mounting frames 43 can realize the provision of more second printed circuit boards 33. For the compressor 6 arranged in the lower subchamber of the electric cabinet 2, the compressor can be connected with the heat exchanger 1 through a pipeline, and in order to avoid the second mounting frame 43 and the pipeline, an avoidance notch 43a can be further arranged on the second mounting frame 43.

The embodiments of the heat exchange device described above may be used with a variety of devices requiring heat exchange, such as air conditioners. The invention also provides an air conditioner, which comprises the embodiment of any heat exchange equipment, and accordingly, the assembly efficiency can be improved.

An example of an assembly process for an electric cabinet is described below in connection with the embodiment of the heat exchange device shown in fig. 2-7. First, the electric cabinet 2 and the heat exchanger 1 (e.g., condenser) which have been integrally formed are provided, and the compressor 6 is installed below the chamber of the electric cabinet 2. After the piping of the compressor 6 and the heat exchanger 1 is welded, the first PCB boards 31 and 32 are mounted on the inner wall surfaces of the left side plate 21 and the right side plate 22, respectively. In the mounting process of the first PCB boards 31 and 32, the first PCB boards 31 and 32 are assembled and fixed with the first mounting brackets 41 and 42, respectively, and then the first PCB board 31 and the first mounting bracket 41 are integrally mounted to the inner wall surface of the left side plate 21, and the first PCB board 32 and the first mounting bracket 42 are integrally mounted to the inner wall surface of the right side plate 22.

After the first PCB boards on both sides are mounted, the second PCB board 33 is assembled with the second mounting frame 43, and after the assembly is completed, the second mounting frame 43 is supported by the first mounting frames 41 and 42 and locked by screws, and is pushed into the cavity of the electric cabinet 2. Thus, the installation inside the electric cabinet 2 is completed, and a larger space is reserved above the cavity, so that the direct wiring between the PCBs can be realized. Finally, the door panel 51 is mounted on the lateral opening of the chamber and is fastened by means of screws.
