Description

Technical Field

[0001] This utility model belongs to the field of refrigerator heat dissipation structure technology, and particularly relates to a rear suction bottom exhaust heat dissipation type compressor chamber and an embedded refrigerator. Background Technology

[0002] Built-in refrigerators occupy a relatively enclosed space, resulting in relatively poor heat dissipation. As disclosed in Chinese Patent CN111457644A, most existing built-in refrigerators use a method where air enters from the rear of the compressor compartment and exits from the sides. Because built-in refrigerators have cabinets on both sides with small gaps, ventilation is poor, leading to inadequate heat dissipation.

[0003] Meanwhile, the refrigerator disclosed in this patent has an axial flow fan installed above the compressor chamber to generate airflow circulation for heat dissipation, which increases the height of the compressor chamber and encroaches on the effective volume of the refrigerator.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, this utility model primarily provides a rear-suction, bottom-discharge heat dissipation compressor chamber, which solves the technical problems of poor heat dissipation and excessive height of existing refrigerator compressor chambers.

[0006] To solve the above problems, this utility model provides a rear-suction, bottom-discharge heat dissipation compressor chamber, including...

[0007] A protective plate is used to form the top and front sides of the press chamber;

[0008] The rear plate forms the rear side of the press chamber; the rear plate is provided with multiple air inlets;

[0011] A condenser is installed inside the compressor chamber;

[0012] A condenser fan is located directly below the condenser; the condenser fan is configured to generate a cooling airflow from top to bottom and discharge the airflow from the underside of the base plate.

[0013] According to the rear-suction bottom-discharge heat dissipation compressor chamber of this utility model, the condenser fan is a centrifugal fan.

[0014] According to the rear-suction bottom-discharge heat dissipation compressor chamber of this utility model, an air-gathering box is provided directly below the condenser and fixed to the base plate; the air intake side of the condenser fan faces the condenser, and the air outlet side is located inside the air-gathering box;

[0030] See Figure 1 This utility model provides a rear-suction, bottom-discharge heat dissipation compressor chamber, including...

[0031] The protective plate 11 is used to form the top surface and front side surface of the press chamber;

[0032] The rear plate 13 is used to form the rear side of the press chamber; the rear plate 13 is provided with a plurality of air inlets 131;

[0033] The base plate 12 is used to form the bottom surface of the press chamber;

[0034] The area enclosed by the guard plate 11, the rear plate 13 and the bottom plate 12 is the press chamber 1;

[0035] Condenser 14 is installed inside the compressor chamber 1;

[0036] See Figure 2 A condenser fan 3 is located directly below the condenser 14; the condenser fan 3 is configured to generate a cooling airflow from top to bottom and discharge the airflow from the underside of the base plate 12.

[0037] The condenser fan 3 generates negative pressure within the compressor chamber 1. External airflow is drawn in through the air inlet 131 of the rear plate 13 and flows downwards from above the condenser 14, exchanging heat with it. The cooled airflow, now at a higher temperature, is then discharged from below the bottom plate 12. This invention utilizes the condenser fan 3 to create an airflow channel between the rear and bottom sides of the compressor chamber, preventing airflow from being discharged from poorly ventilated sides, thus improving heat dissipation efficiency and effectiveness.

[0038] As one embodiment, the condenser fan 3 is a centrifugal fan with a thin thickness, which can effectively reduce the height of the compressor chamber 1.

[0039] See Figure 3 and Figure 4As one embodiment, an air-collecting box 2 is provided directly below the condenser 14 and is fixed to the base plate 12; the air intake side of the condenser fan 3 faces the condenser 14, and the air outlet side is located inside the air-collecting box 2.

[0040] The bottom of the air collecting box 2 is provided with an exhaust duct 22 that slopes towards the front side of the compressor chamber, and the outlet of the exhaust duct 22 is located on the lower side of the base plate 12. The airflow discharged from the condenser fan 3 is collected in the air collecting box 2 and discharged forward from the exhaust duct 22 along the lower side of the compressor chamber. This prevents hot gas from accumulating in the surrounding area of ​​the compressor chamber, causing the temperature to rise, and improves heat dissipation efficiency.

[0041] Furthermore, the air collecting box 2 is also provided with an air guide shroud 21 that surrounds the outside of the condenser fan 3; the opening of the air guide shroud 21 is funnel-shaped, which generates a converging effect on the airflow, thereby increasing the flow rate of the cooling airflow and improving the heat dissipation effect.

[0042] As one embodiment, the base plate 12 is provided with an area for installing the compressor, and the base plate 12 in this area is provided with an air intake hole 121; external airflow is drawn into the direct-blowing compressor through the air intake hole 121 to dissipate heat, and the hot airflow is uniformly drawn out and discharged by the condenser fan 3.

[0043] Furthermore, the air intake 121 is elongated, providing a large airflow coverage area and good heat dissipation for the compressor.

[0044] See Figure 5 As one embodiment, the air inlet 131 of the rear plate 13 is provided with a guide plate 132 that is inclined upward towards the compressor chamber 1; the external airflow is guided by the guide plate 132 and enters the compressor chamber 1 in an inclined upward direction, which can quickly reach the top of the condenser 14, improve the circulation speed of the cooling airflow, and improve the heat dissipation efficiency.

[0045] Preferably, the guide plate 132 has an inclination angle of 45°, which allows the airflow to reach the top of the condenser 14 smoothly and minimizes obstruction of the air inlet 131.

[0046] Furthermore, the air inlet 131 is a horizontally arranged strip-shaped hole; the intake airflow is guided by each air inlet 131 and enters the compressor cavity in a laminar flow state, with a fast flow speed and improved heat dissipation effect.

[0047] This utility model also provides an embedded refrigerator, which has a cabinet and the rear side of the cabinet is provided with the rear suction bottom exhaust heat dissipation type compressor chamber;

[0048] The embedded refrigerator of this invention utilizes the gap between the rear and bottom sides to form an airflow channel for heat dissipation, ensuring heat dissipation within a relatively enclosed space.

[0049] Optionally, the refrigerator body of this utility model can be selected from the known built-in refrigerator body structure.

[0050] In summary, this invention provides a rear-suction, bottom-exhaust cooling compressor chamber. A condenser fan generates negative pressure within the compressor chamber, drawing in external airflow through the air inlet on the rear plate and flowing downwards from above the condenser, exchanging heat with it. The cooled airflow, now at a higher temperature, is then exhausted from below the bottom plate. This invention utilizes the condenser fan to create an airflow channel between the rear and bottom sides of the compressor chamber, preventing airflow from escaping through poorly ventilated areas and improving heat dissipation efficiency and effectiveness. This invention also provides an embedded refrigerator.

[0051] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
