Abstract

This utility model relates to air conditioning, specifically providing a housing and an air conditioner, aiming to solve the problem of effectively preventing external liquids from entering the housing through the vents while ensuring good heat dissipation. To this end, the housing of this utility model includes a main body, a radiator, and a baffle. The end of the top plate furthest from the vent and the bottom of the vent are both set on a reference surface. The reference surface intersects the baffle at a reference line, and the lower end of the baffle is below the reference line. This utility model sets a baffle outside the vent, with its lower end below the reference line.

This structure also ensures smooth airflow through the vents, achieving good heat dissipation and addressing the dual requirements of liquid prevention and heat dissipation.

Description

Technical Field

[0001] This utility model relates to air conditioners, specifically providing a housing and an air conditioner. Background Technology

[0002] As the overall performance and functionality of household appliances and various industrial equipment continue to improve, the workload of their internal control units (such as computer boards, driver boards, and other core components) is also gradually increasing, thus placing higher and more stringent requirements on their heat dissipation capabilities and structures. To ensure the stability and reliability of key components such as computer boards during long-term operation, current technology typically installs dedicated heat sinks inside the appliance enclosure and reserves several ventilation openings on the outer wall of the enclosure. These, in conjunction with the heat sink, form an effective heat dissipation channel, thereby aiding in air convection. This method allows the heat generated inside the enclosure by the operation of electronic components to be dissipated in a timely manner, preventing excessive temperature from adversely affecting system performance and further improving the overall heat dissipation efficiency and lifespan of the equipment.

[0003] Due to the presence of heat dissipation vents, it is difficult to maintain a completely sealed enclosure. The rotating fan blades may also splash condensation into the enclosure. Once this happens, moisture will inevitably come into contact with internal electronic components or circuit boards, easily causing short circuits and potentially leading to corrosion or oxidation of metal parts. This reduces the reliability and stability of the equipment, shortening its overall lifespan. Therefore, effectively preventing rainwater or condensation from entering the enclosure through the vents while ensuring good heat dissipation is a problem that current technology urgently needs to solve.

[0004] Therefore, there is an urgent need in this field for a housing and air conditioner to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to effectively prevent external liquids from entering the interior of the box through the heat dissipation vents while ensuring good heat dissipation of the box.

[0006] In a first aspect, the present invention provides a box body, the box body including a main body, a radiator and a baffle, a heat dissipation vent is provided on the outer wall of the main body, the radiator is disposed inside the main body near the heat dissipation vent, the radiator includes a top plate, the baffle is disposed outside the heat dissipation vent, and the baffle is spaced apart from the outer wall of the main body;

[0007] The end of the top plate away from the heat dissipation vent and the bottom of the heat dissipation vent are both set on a reference surface. The reference surface intersects the baffle at a reference line, and the lower end of the baffle is lower than the reference line.

[0008] In a specific embodiment of the above-mentioned box, the distance between the lower end of the baffle and the baseline in the vertical direction ranges from 3mm to 4mm.

[0009] In a specific embodiment of the above-mentioned housing, the baffle is an arc-shaped plate that protrudes obliquely downward toward the heat dissipation vent.

[0010] In a specific embodiment of the above-mentioned housing, the lower part of the baffle is spaced apart from the outer wall of the main body to form a lower opening, through which the airflow discharged from the heat dissipation vent can be discharged.

[0011] The upper part of the baffle is spaced apart from the outer wall of the main body to form an upper opening, through which the airflow discharged from the heat dissipation vent can be discharged.

[0012] In a specific embodiment of the above-mentioned box, the box further includes a connecting plate, one end of which is connected to the side of the baffle, and the other end is connected to the main body, so that the baffle is fixedly connected to the main body.

[0013] In a specific embodiment of the above-mentioned housing, the connecting plate is provided with a through hole, through which the airflow discharged from the heat dissipation port can be discharged.

[0014] In a specific embodiment of the above-mentioned box, a water tank is provided at the bottom of the main body, and a drain outlet is provided at the bottom of the water tank.

[0015] In a specific embodiment of the above-described housing, the water tank is located at the end below the radiator away from the heat dissipation port.

[0016] In a specific embodiment of the aforementioned housing, the radiator further includes a plurality of vertically arranged heat sinks, which are spaced apart, and the upper ends of the heat sinks are connected to the top plate.

[0017] In a second aspect, the present invention provides an air conditioner that includes the aforementioned housing.

[0018] By employing the above technical solution, this invention includes a baffle outside the heat dissipation vent, with its lower end below the baseline. This arrangement effectively prevents most liquid from entering the vent. Simultaneously, for the very small amount of liquid that might enter, the baffle spatially restricts its movement, preventing it from penetrating deeper into critical areas of the main body. This avoids the risk of short circuits or corrosion caused by direct contact between the liquid and core electronic components such as control units and circuit boards. Furthermore, while providing protection, this structure ensures smooth airflow, forming a good airflow channel through the vent for efficient heat dissipation. Therefore, this solution achieves a balance between liquid protection and heat dissipation, addressing both needs and significantly improving the overall reliability and lifespan of the equipment.

[0019] Furthermore, by forming lower and upper openings between the upper and lower parts of the baffle and the outer wall of the main body, the airflow discharged from the heat dissipation vent can be discharged through multiple paths, thereby ensuring that the airflow can be more fully diffused and guided after passing through the heat dissipation vent. This avoids the local heat accumulation phenomenon that may be caused by airflow obstruction and ensures that the heat inside the box can be carried away more efficiently.

[0020] Furthermore, the connecting plate securely connects the baffle to the main body, enhancing the overall structural stability. Even further, the connecting plate is equipped with through holes, allowing airflow to escape. This design not only effectively increases the number of exhaust channels and widens the airflow path, but also reduces airflow resistance to some extent, preventing heat accumulation caused by localized airflow obstruction. As a result, heat inside the enclosure can be dissipated more quickly and evenly, further improving overall heat dissipation performance.

[0021] Furthermore, by installing a water tank at the bottom of the enclosure with a drain outlet at its base, liquid falling through the baffle can be effectively collected and promptly discharged, preventing long-term liquid accumulation inside the enclosure and avoiding potential damage to the control unit, electronic components, and other critical parts, thus ensuring the safe operation and reliability of the equipment. Simultaneously, placing the water tank below the radiator and away from the vents effectively prevents rainwater or condensate entering through the vents from flowing uncontrolled into the enclosure body, further enhancing the overall waterproof performance. This arrangement allows critical components inside the enclosure to remain dry under complex environmental conditions, ensuring efficient heat dissipation while maintaining good safety and stability during long-term operation, thereby significantly enhancing the reliability and lifespan of the entire system.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] To address the issue of effectively preventing external liquids from entering the casing through the vents while ensuring good heat dissipation, this embodiment discloses an air conditioner. The air conditioner includes an outdoor unit, a fan, and a casing. The fan is located inside the outdoor unit, and its specific structure is the same as that of fans in existing air conditioner outdoor units; its specific structure will not be described in detail here.

[0039] The enclosure includes the main body, radiator, baffle, and connecting plate.

[0040] Reference Figure 1 and Figure 2 The main body 1 is shaped like a shell with an internal cavity structure. This cavity can accommodate the control unit 7, the radiator 2, and other related components. The main body 1 is fixedly installed inside the outdoor unit. An air inlet and a heat dissipation vent 11 are provided on the outer wall of the main body 1, with the heat dissipation vent 11 connecting to the chamber where the fan 6 is located. When the fan 6 rotates, it drives external air through the air inlet to smoothly enter the interior of the main body 1, forming an effective airflow circulation. Simultaneously, the fan 6 can also expel the heat generated inside the main body 1 by the airflow from the heat dissipation vent 11, thereby achieving internal temperature regulation and improving heat dissipation, ensuring the stability and reliability of key components such as the control unit 7 and the radiator 2 during long-term operation.

[0041] The heat sink 2 is used to dissipate heat from the control unit 7 inside the main body 1. In this embodiment, refer to... Figure 3 The radiator 2 includes a top plate 21 and multiple heat sinks 22, which are spaced apart. The top plate 21 of each heat sink 22 is connected to the top plate 21, so that the radiator 2 forms a whole. (Refer to...) Figure 2The top plate 21 is positioned inside the main body 1 near the control unit 7, effectively transferring the heat generated by the control unit 7 during operation to the heat sink 22. Furthermore, the heat sink 2 is positioned near the heat dissipation vent 11, allowing airflow inside the main body 1 to smoothly flow through the gaps between the heat sink 22 to the heat dissipation vent 11 as it passes through the heat sink. During the airflow through the heat sink 22, heat is carried away by the air, achieving efficient heat dissipation for the control unit 7 and related components. Simultaneously, this structure ensures smooth airflow circulation inside the enclosure, improving heat dissipation efficiency, preventing localized overheating, and further guaranteeing the long-term stability and reliability of the equipment.

[0042] Reference Figure 1 The baffle 3 is positioned outside the heat dissipation vent 11. (See reference...) Figure 4 When fan 6 rotates, water from fan 6 or the bottom of the outdoor unit can easily splash into the heat dissipation vent 11. The baffle 3 effectively prevents this water from entering the heat dissipation vent 11, thus avoiding direct contact between water and the control unit 7 inside the main body 1, reducing the risk of short circuits, corrosion, or performance degradation caused by liquid intrusion. This structural design not only improves the waterproof capability of the enclosure but also enhances the reliability and safety of the equipment under complex environmental conditions while ensuring unobstructed heat dissipation channels.

[0043] The connecting plate is used to connect the baffle 3 and the main body 1. In this embodiment, the connecting plate includes a left connecting plate 51 and a right connecting plate 52, as detailed below. Figure 1 The left side of baffle 3 is connected to one end of the left connecting plate 51, and the other end of the left connecting plate 51 is connected to the main body 1; the right side of baffle 3 is connected to one end of the right connecting plate 52, and the other end of the right connecting plate 52 is connected to the main body 1, so that baffle 3 is connected to the main body 1. Furthermore, baffle 3, left connecting plate 51, right connecting plate 52, and main body 1 are integrally formed to enhance the stability and robustness of the overall structure. Furthermore, both left connecting plate 51 and right connecting plate 52 are provided with through holes 53, allowing air exhausted from heat dissipation vent 11 to smoothly pass through the through holes 53 and be discharged, forming additional exhaust channels. This not only increases the number of airflow exhaust paths and improves airflow smoothness, but also effectively reduces airflow resistance, thereby further improving the heat dissipation effect inside the housing and ensuring the temperature control and reliability of the control unit 7 and other key components during operation.

[0044] Reference Figure 1 and Figure 2 The upper part of the baffle 3 is spaced apart from the outer wall of the main body 1 to form an upper opening 32. The lower part of the baffle 3 is spaced apart from the outer wall of the main body 1 to form a lower opening 31. Air discharged from the heat dissipation vent 11 can be discharged through the upper opening 32 and the lower opening 31.

[0045] The baffle 3 is shaped like an arc, so that the lower part of the baffle 3 is closer to the outer wall of the main body 1 than the upper part of the baffle 3. This arrangement reduces the amount of liquid flowing into the heat dissipation port 11. Furthermore, the end of the top plate 21 of the radiator 2 away from the heat dissipation port 11 is on the same plane as the lower end of the heat dissipation port 11, and this plane is designated as the reference plane 4. The reference plane 4 intersects the baffle 3 at a straight line, which is designated as the reference line. The lower end of the baffle 3 is lower than this reference line, so that the baffle 3 can further reduce the amount of liquid flowing into the heat dissipation port 11. Even further, the distance between the lower end of the baffle 3 and the reference line in the vertical plane ranges from 3mm to 4mm. This arrangement reduces the amount of liquid flowing into the heat dissipation port 11 and prevents the baffle 3 from interfering with the rotation of the fan 6.

[0046] Continue to refer to Figure 2 The main body 1 contains a water tank 12 for collecting liquid entering the main body 1 from the heat dissipation vent 11. The water tank 12 is located on the bottom of the radiator 2, away from the heat dissipation vent 11. Furthermore, the bottom of the water tank 12 has a drain outlet 13, through which water in the water tank 12 can be discharged to the outside of the main body 1. (See reference...) Figure 5 Baffle 3 can block most of the liquid. Figure 5 The left arrow indicates the liquid blocked by baffle 3; only a small portion of the liquid enters the heat dissipation port 11 through the lower opening 31. The movement direction of the liquid entering the heat dissipation port 11 is restricted by baffle 3, so that this portion of liquid will collide with the top plate 21 of the radiator 2 and fall to the bottom of the main body 1, or fall to the bottom of the main body 1 after exhausting its kinetic energy. Figure 5 The bold arrows indicate the direction of liquid movement into the vent 11. Due to the restriction of the baffle 3, the liquid entering the radiator 2 will not fall beyond the water tank 12. Therefore, the water tank 12 can collect the liquid entering the vent 11 and discharge it from the drain 13. The liquid that does not enter the water tank 12 is located between the water tank 12 and the vent 11, and this part of the liquid will not affect the control unit 7 inside the main body 1. Furthermore, the bottom of the main body 1 between the water tank 12 and the vent 11 is set as a slope, which is inclined towards the water tank 12 so that the liquid on the slope flows into the water tank 12.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
