This utility model provides a filtration device for a laminator, relating to the field of laminator filtration technology. It aims to solve the problems of poor filtration efficiency in existing vacuum pumps that use conventional paper filter elements to filter the gas generated during vacuuming. This allows impurities such as welding slag and iron filings to penetrate the filter element and enter the vacuum pump cavity, affecting normal operation. Furthermore, the accumulation of impurities and dust necessitates frequent inspection, maintenance, and upkeep of the vacuum pump and filter, increasing maintenance costs. The proposed device includes a vacuum pump system with a laminator vacuum valve installed on its left side. A filter tank system is installed between the vacuum pump system and the laminator vacuum valve. The tank serves as a pre-vacuum tank to pre-vacuum the cavity. A bypass design is used; after pre-vacuuming, the filter tank's function is disabled, and the pump directly evacuates the cavity, reducing pump load, effectively improving equipment evacuation efficiency, reducing vacuum pump filter consumption, and minimizing pump maintenance.

This invention discloses a multi-powered combined unmanned aerial vehicle (UAV) intelligent cooling system, specifically comprising a core control unit, a power unit, an execution layer unit, a perception layer unit, and a decision-making layer unit. The physical components of each unit are integrated into a frame to form a flight module. The core control unit coordinates the operating conditions of the power unit and the cooling actions of the execution layer unit via a data bus. Temperature sensors in the perception layer unit collect real-time temperature data from the engine block, radiator, and main cooling channel. The decision-making layer unit dynamically generates drive signals based on the temperature data and the engine ECU's requirements. The system innovatively uses hollow tubing within the frame to form the main coolant channel, combining a liquid-cooled engine with an air-cooled radiator to form a composite cooling circuit. Intelligent flow regulation is achieved through solenoid valves and a circulating water pump, providing three modes: basic coordination, differential temperature control, and fuel preheating. This invention upgrades the UAV cooling system from passive heat dissipation to active thermal management, improving the operational efficiency and reliability of multi-powered UAVs.

This invention discloses a liquid-cooled circulating cooling battery swapping cabinet for liquid-cooled batteries, relating to the technical field of battery thermal management and battery swapping equipment. The invention includes: a guide slide installed inside the cabinet; a battery swapping chamber slidably connected to the inner wall of the guide slide; an elastic telescopic rod fixedly connected to the inner wall of the cabinet; an electric telescopic rod fixedly connected to the left side of the battery swapping chamber; and a heat dissipation mechanism for ventilation and heat dissipation provided on the inner wall of the battery swapping chamber. This invention can cool the battery during the battery swapping process of new energy liquid-cooled batteries, avoiding excessively high battery temperatures and low swapping efficiency due to long swapping times. The cooling medium circulates in a closed loop within the tank, significantly increasing the heat exchange area and thermal conductivity between the battery and the cooling medium, preventing localized high temperatures and rapid temperature rise, and improving charging safety and battery lifespan.

The application discloses a multi-dimensional uniform-temperature radiator, which comprises a front-end cavity of a radiator frame, a mounting plate arranged in the front-end cavity, an adjusting groove arranged at the rear end of the mounting plate, movable mounting strips arranged at the two sides of the adjusting groove, an internal cavity above a side heat dissipation plate and a middle heat dissipation plate, a distribution frame fixed in the internal cavity above the side heat dissipation plate and the middle heat dissipation plate, an adjusting assembly arranged in the mounting plate and the mounting disc, upper support plates slidably arranged at the two sides of the upper half of the middle heat dissipation plate and the side heat dissipation plate, telescopic rods fixed between the upper support plates and lower support plates on the middle heat dissipation plate and the side heat dissipation plate, air guide hoses connected between the two sides of the middle heat dissipation plate and the side heat dissipation plate, and support rods rotatably arranged between the middle of the middle heat dissipation plate and the upper support plates and the lower support plates on the side heat dissipation plate. The multi-dimensional uniform-temperature radiator can uniformly dissipate heat from inside to outside and can be suitable for electric elements of different sizes.
