Description

Technical Field

[0001] The utility model relates to the technical field of loads, in particular to an exhaust hood which is adjustable in transverse and longitudinal directions. Background Art

[0002] There is a resistor module inside the load box, and the resistor module generates a lot of heat when it works. To ensure the normal use of the load, there is a cooling fan inside the load box, an air inlet is provided on the side of the load box, and an air outlet for heat dissipation is provided on the top of the load box. The cooling fan forces air cooling to quickly discharge the heat from the air outlet to achieve the purpose of heat dissipation. Because the load box is used outdoors, the air outlet is generally provided with an air guide cover to prevent rainwater from flowing back into the load box. The air guide cover also has the function of guiding the wind direction, so that the hot air is blown out in a certain direction. For a high-power load box, the temperature of the air outlet will reach 300-400℃, which will cause the temperature of the side wall of the air guide cover to be too high, which may easily cause accidents, and will also cause the paint on the surface of the air guide cover to fall off, affecting the appearance of the product. Therefore, the applicant has previously developed a waterproof, heat-insulating, wind-guiding hood as disclosed in the Chinese patent document with the announcement number CN209748998U, including a hood body, a wind-guiding channel formed in the hood body, the hood body including continuous vertical sections and transverse sections, the upper port of the vertical section is connected to the transverse section, and the port of the transverse section away from the vertical section is provided with a wind-guiding sheet for guiding the wind upward, and the hot air will be guided to blow upward to prevent the hot air from flowing back from the air inlet of the load box. The side wall of the hood body includes an outer partition and an inner partition, and the side of the inner partition is sprayed and covered with a high-temperature resistant paint layer, so that the temperature of the outer partition of the hood body will not be too high, reducing the risk of accidents.

[0003] Another example is the multifunctional load box disclosed in the Chinese patent document with the announcement number CN212586435U. The frame panel above the load compartment is provided with an air guide cover, which is connected to the load compartment. The air guide cover has an arc-shaped air guide duct, which is formed by an air guide cover shell. A plurality of air guide blades arranged up and down are provided at the air outlet of the air guide cover. The air guide blades can be rotated around the blade shaft to open and close to form a venetian blind structure according to the wind pressure generated by the start and stop of the fan. Connecting rods are designed on both sides of the air guide blades to achieve simultaneous opening and closing.

[0004] Another example is a load air-cooling air guide device disclosed in a Chinese patent document with publication number CN114286587A, which includes a cylindrical cover body and a fan arranged below the cover body. The air inlet at the bottom of the cover body is downwardly connected to the fan, and the air outlet at the top of the cover body is upwardly connected to the outside. The inside of the cover body is provided with a plurality of partitions arranged horizontally, and a heat dissipation air duct that passes through from top to bottom is formed between each two adjacent partitions. A water receiving trough is provided at the lower end of the partition, and the water receiving trough is connected to the outside of the cover body; the partition is S-shaped, so that the upper end of the heat dissipation air duct is aligned downward with the side wall of the partition, so that the outside rainwater enters from the air outlet and is guided to the water receiving trough along the side wall of the partition. By setting the partition, the vertically falling rainwater is guided to flow to the side wall of the partition until it flows into the water receiving trough for discharge, thereby preventing the rainwater from falling on the fan or the load below.

[0005] The above air guides have their own characteristics, but all have only one air outlet, so they can only discharge air in a single direction. Although hot air always tends to surge vertically, in order to prevent rain from entering the load through the air guide, the existing air guide openings are generally horizontal, but even on sunny days, air can only be discharged horizontally, affecting the heat dissipation effect. Summary of the invention

[0006] In view of the above technical problems in the prior art, the utility model provides an exhaust hood which is adjustable in both transverse and longitudinal directions.
