Description

Technical Field

[0001] This utility model relates to the field of scroll compressor technology, and in particular to a compressor housing. Background Technology

[0002] As a highly efficient and energy-saving fluid machine, the scroll compressor occupies an important position in the refrigeration and air conditioning field. Its casing is a key basic component that supports and houses various parts. The casing usually adopts a cylindrical structure, with multiple bosses, internal holes, end face pin holes, and various grooves on the outer cylinder wall. During processing, the cast workpiece needs to be drilled, grooved, or machined at the end face in sequence.

[0003] In some existing scroll compressors, the refrigerant inlet is located at the end of the motor housing during operation. This allows the intake airflow to cool the motor. To improve cooling efficiency, existing technologies use tangential intake holes in the motor housing to guide the airflow tangentially, forming a cyclone. This extends the airflow path and improves heat dissipation. However, due to the thick motor housing wall, the intensity of the oblique turbulence formed by the oblique holes is not high, resulting in insufficient scroll rotation. Furthermore, since the motor controller also generates heat, but the airflow direction is usually away from the controller, it cannot provide sufficient cooling to the controller area. Therefore, controller cooling generally relies on natural cooling or a separate cooling mechanism, which limits the controller's operating power or increases cooling costs, indicating room for further improvement.

[0005] To achieve the above objectives, a compressor housing is provided, comprising a stationary disk housing and a moving disk housing. A motor housing is fixedly connected to one end of the moving disk housing away from the stationary disk housing, and a controller housing is fixedly connected to one end of the motor housing away from the moving disk housing. A controller mounting plate is provided on the inner side of the motor housing away from the moving disk housing. Multiple heat dissipation baffles are equidistantly arranged on the side of the controller mounting plate away from the controller housing. An air inlet ring seat is provided on the outer side of the motor housing near the controller mounting plate. An air inlet seat is provided on the top of the air inlet ring seat. An air inlet is provided in the middle of one side of the air inlet seat. Multiple oblique holes are equidistantly arranged on the inner side of the air inlet ring seat.

An air outlet is provided in the middle of the end of the stationary disc housing away from the moving disc housing. A safety valve hole is provided on the side of the stationary disc housing away from the air outlet.

[0006] According to the compressor housing, the housing connection structure includes a stationary plate connecting seat, a moving plate connecting seat, bolt fixing flanges, bolt holes, positioning grooves, and positioning flanges. Bolt fixing flanges are provided at six equal divisions of the stationary plate connecting seat and the moving plate connecting seat. Bolt holes are provided on each of the multiple bolt fixing flanges. Positioning grooves are provided on the two upper bolt fixing flanges of the stationary plate connecting seat. Positioning flanges are provided at the corresponding positions of the upper bolt fixing flanges of the moving plate connecting seat and the positioning grooves.

[0007] According to the compressor housing, the positioning groove is a U-shaped groove structure, the shape of the positioning flange corresponds to the positioning groove, and the directions of the positioning flange and the positioning groove are both set centripetally relative to the motor shaft.

[0008] According to the compressor housing, a mounting base is fixedly connected to the bottom of the motor housing.

[0009] According to the housing of the compressor, a rotor shaft hole is provided at the center of the controller mounting plate.

[0010] According to the casing of the compressor, the plurality of heat dissipation baffles have gradually varying heights, and the height ratio of the inner edge end near the rotor shaft hole to the outer edge end is 2.5:1.

[0011] According to the casing of the compressor, the position of the air inlet corresponds to the air intake direction of the oblique hole and the heat dissipation baffle.

[0012] The above solution has at least one of the following beneficial effects: 1. This utility model is equipped with an air inlet ring seat and an oblique hole. In conjunction with the heat dissipation baffle on the controller mounting plate, the controller and other equipment can be mounted on the controller mounting plate. While the heat dissipation baffle increases the vortex rotation speed by turbulence, it can also transfer the heat of the controller mounting plate into the refrigerant, thereby improving the heat dissipation efficiency inside the controller housing and enhancing the practicality of the device.

[0013] 2. The present invention has a housing connection structure between the stationary plate housing and the moving plate housing. The positioning grooves and positioning flanges on both sides of the top can cooperate with each other, which not only forms a foolproof design to prevent the installer from making a wrong orientation when installing the stationary plate housing, but also allows for direct positioning during installation, which facilitates the installation and fixing of bolts and enhances the practicality of the device.

With the heat dissipation baffle 8 provided on the controller mounting plate 6, the controller and other equipment can be installed on the controller mounting plate 6. While the heat dissipation baffle 8 turbulences and increases the vortex rotation speed, the heat of the controller mounting plate 6 can be introduced into the refrigerant by the heat dissipation baffle 8, thereby improving the heat dissipation efficiency inside the controller housing 4. An oil filling hole 12 is provided on the top of the moving plate housing 2, and a mounting base 9 is fixedly connected to the bottom of the motor housing 3.

The directions of positioning flanges 56 and positioning grooves 55 are both set towards the center of the motor shaft. The positioning grooves 55 and positioning flanges 56 arranged symmetrically on both sides of the top cooperate with each other, which not only forms a foolproof design to prevent installers from making mistakes in the installation direction when installing the stationary plate housing 1, but also allows for direct positioning during installation, which facilitates the installation and fixing of bolts.

During installation, the housing connection structure 5 can cooperate with the positioning grooves 55 and positioning flanges 56 symmetrically set on both sides of the top. This not only forms a foolproof design to prevent the installer from making a mistake in the installation direction of the stationary housing 1, but also allows for direct positioning during installation, facilitating the installation and fixing of bolts.
