[0049] Figure 1 It is a cross-sectional view of a horizontal compressor according to an embodiment of the present utility model. Figure 2 yes Figure 1 A partial enlarged view of the . Figure 3 yes Figure 1 Cross-sectional view along the AA axis. Figures 1 to 3As shown, a horizontal compressor of the present invention comprises: a middle shell 1 and a front shell together forming a first cavity 5, an air inlet suction plate 2, and a rear shell 3. The first cavity 5 accommodates a motor, an orbiting scroll, and a stationary scroll. The air inlet suction plate 2 is disposed on the side of the motor facing away from the orbiting scroll and docks with the middle shell 1. An annular flange protruding from the middle shell 1 is provided on the first side of the air inlet suction plate 2, and an inwardly contracted step-shaped air intake hole is provided through the annular flange. The inwardly contracted step-shaped air intake hole includes an outer section air intake 21 that is interconnected and an inner section air intake 22 having a smaller diameter than the outer section air intake 21. The rear shell 3 and the second side of the air inlet suction plate 2 together form a second cavity 4 that accommodates a power circuit module. The axis of the outer section air intake 21 and the axis of the inner section air intake 22 are not collinear. The inner section air intake 22 guides the refrigerant entering from the outer section air intake 21 to move at least toward the second cavity 4 during the flow process. The horizontal compressor and new energy vehicle of the present invention can accelerate the refrigerant flow rate and enhance the cooling effect on the power circuit module and improve the compressor efficiency through the stepped variable diameter structure of the air intake without adding additional parts.
[0050] In a preferred embodiment, continue to refer to Figure 2 The relationship between the diameter D1 of the outer section air intake port 21 and the diameter D2 of the inner section air intake port 22 is: 0.53≤D2 / D1≤0.68, but this is not used as an example.
[0051] In a preferred embodiment, the relationship between the depth L1 of the outer section air intake port 21 and the depth L2 of the inner section air intake port 22 is: 0.3≤L2 / L1≤1, so that the refrigerant flows through the air intake pressure plate and enters a throttling section, thereby increasing the refrigerant flow rate and enhancing the cooling effect on the IPM, but this is not an example.
[0052] In a preferred embodiment, the tubular inner wall of the inner section air intake port 22 is tangent to the plane where the first side of the air intake port air intake plate 2 is located, but this is not an example.
[0053] In a preferred embodiment, the axis E1 of the outer air intake port 21 passes through the annular flange along the thickness direction of the annular flange. The axis E1 of the outer air intake port 21 and the axis E2 of the inner air intake port 22 can be parallel or inclined, but this is not an example.
[0054] In a preferred embodiment, the distance between the axis E2 of the inner section air intake port 22 and the bottom surface of the rear shell is W, (D2 / 2) mm≤W≤(D2 / 2+3) mm, so as to guide the air intake flow toward the IPM and enhance the cooling effect on the IPM, but this is not used as an example.
[0055] In a preferred embodiment, the first end of the inner air intake 22 is connected to the outer air intake 21, and the second end of the inner air intake 22 extends toward the projection area of the power circuit module on the first side of the air intake pressure plate 2, based on the plane of the air intake pressure plate 2. This is equivalent to angling the inner air intake 22 about the Z-axis toward the bottom surface of the rear housing to direct the intake air flow toward the location of the IPM (IPM stands for Intelligent Power Module), but this is not an example.
[0056] In a preferred embodiment, see Figure 1 An oblique transition is provided between the outer section air intake port 21 and the inner section air intake port 22 , and the value range of the oblique transition angle α is 105°≤∠α≤165°, but this is not used as an example.
[0057] In a preferred embodiment, the refrigerant flow rate through the inner section air intake port 22 is greater than the refrigerant flow rate through the outer section air intake port 21 , but this is not an example.
[0058] The stepped variable diameter structure of the air intake of the present invention increases the refrigerant flow rate and enhances the cooling effect on the IPM; the eccentric design of the inner air intake 22 (small diameter flow channel) makes the flow channel close to the bottom surface of the rear shell, thereby enhancing the cooling effect on the IPM; the inner air intake 22 is designed at an inclined angle relative to the outer air intake 21 (large diameter flow channel), so that the flow channel is directed to the area where the IPM is located, thereby enhancing the cooling effect on the IPM; compared with the air intake structure without a stepped structure, the bottom surface of the rear shell can be closer to the compressor pump body, which can enhance the cooling effect on the controller components and increase the controller structure design space.
[0059] The following is in conjunction with the instructions Figures 1 to 3 To introduce the specific implementation of the horizontal compressor of the utility model:
[0060] See also Figures 1 to 3As shown, in the horizontal compressor of the present invention, the middle shell 1 and the front shell together form a first cavity 5, an air inlet suction plate 2, and a rear shell 3. The first cavity 5 accommodates the motor, the orbiting scroll, and the fixed scroll. The air inlet suction plate 2 is arranged on the side of the motor facing away from the orbiting scroll and docks with the middle shell 1. The first side of the air inlet suction plate 2 is provided with an annular flange protruding from the middle shell 1, and an inward-contracted step-shaped air intake hole is provided through the annular flange. The inward-contracted step-shaped air intake hole includes an outer section air intake 21 that is interconnected and an inner section air intake 22 that has a smaller diameter than the outer section air intake 21. The rear shell 3 and the second side of the air inlet suction plate 2 together form a second cavity 4 that accommodates the power circuit module. The axis of the outer section air intake 21 and the axis of the inner section air intake 22 are not collinear. The inner section air intake 22 guides the refrigerant entering from the outer section air intake 21 to move at least toward the second cavity 4 during the flow process. The relationship between the diameter D1 of the outer air intake port 21 and the diameter D2 of the inner air intake port 22 is: 0.53 ≤ D2 / D1 ≤ 0.68. The relationship between the depth L1 of the outer air intake port 21 and the depth L2 of the inner air intake port 22 is: 0.3 ≤ L2 / L1 ≤ 1. The tubular inner wall of the inner air intake port 22 is tangent to the plane of the first side of the air inlet intake platen 2. The distance W between the axis E2 of the inner air intake port 22 and the bottom surface of the rear housing is (D2 / 2) mm ≤ W ≤ (D2 / 2 + 3) mm. This guides the intake airflow toward the IPM, enhancing the cooling effect on the IPM. The first end of the inner air intake port 22 is connected to the outer air intake port 21. The second end of the inner air intake port 22 extends toward the projection area of the power circuit module on the first side of the air inlet intake platen 2, based on the plane of the air inlet intake platen 2. An oblique transition is provided at the outer section air intake port 21 and the inner section air intake port 22, and the value range of the angle α of the oblique transition is 105°≤∠α≤165°, but this is not used as an example. The refrigerant flow rate through the inner section air intake port 22 is greater than the refrigerant flow rate through the outer section air intake port 21. The utility model designs the compressor air intake port as a two-stage variable diameter structure, the first section is to match the pipe diameter of the air-conditioning system, and the second section is a guide and acceleration channel for the refrigerant intake airflow. Through this structural scheme, the compressor intake airflow is enhanced with an accelerated throttling process after passing through the air intake port, thereby increasing the refrigerant flow rate and increasing the cooling effect on the controller. Compared with the ordinary air intake port, the bottom surface of the rear shell can be closer to the compressor pump body side while the position of the compressor and the whole vehicle matching the air intake port remains unchanged, and there is more axial space for the arrangement of the control panel components.
[0061] Figure 4 This is a partial enlarged view of a horizontal compressor according to another embodiment of the present invention. Figure 4As shown, another horizontal compressor of the present invention differs from the previous horizontal compressor in that the first end of the inner section air intake port 22 is connected to the outer section air intake port 21, and the second end of the inner section air intake port 22 extends toward the second cavity 4 in a vertical direction perpendicular to the plane of the inlet air intake plate 2. This is equivalent to the inner section air intake port 22 being angled around the X-axis toward the IPM module area, directing the intake air flow toward the IPM location area, but this is not an example.
[0062] According to actual needs, the first end of the inner section air intake port 22 can also be set to be connected to the outer section air intake port 21, and in the vertical direction perpendicular to the plane where the air inlet air intake pressure plate 2 is located, the second end of the inner section air intake port 22 extends toward the direction close to the second cavity 4, and in the plane direction based on the air inlet air intake pressure plate 2, the second end of the inner section air intake port 22 also extends toward the projection area of the power circuit module on the first side of the air inlet air intake pressure plate 2, but this is not used as an example.
[0063] The present invention also provides a new energy vehicle utilizing the aforementioned horizontal compressor. The remaining relevant technical features and effects are as previously described and will not be elaborated upon here. This invention contributes to improving the overall NVH (Noise, Vibration, and Harshness) of new energy vehicles. This is a comprehensive measure of vehicle manufacturing quality that is most directly and superficially perceived by vehicle users.
[0064] In summary, the horizontal compressor and new energy vehicle of the present invention can accelerate the refrigerant flow rate, enhance the cooling effect on the power circuit module, and improve the compressor efficiency through the stepped variable diameter structure of the air intake without adding additional parts.
[0065] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
