Description

Technical Field

[0001] This utility model relates to the field of airport de-icing technology, and in particular to a heater. Background Technology

[0002] When an aircraft operates in icing weather conditions, supercooled water droplets or freezing rain in the air rapidly condense into ice on the aircraft's surface. Icing on critical aerodynamic surfaces such as the wings and tail directly disrupts the streamlined profile, leading to a significant deterioration in aerodynamic characteristics. The irregular shape of the ice layer can cause airflow separation, reducing lift, increasing drag, and even altering critical angle-of-attack parameters. In extreme cases, it can lead to increased stall speed and sluggish handling response.

[0003] Airport de-icing vehicles are indispensable special support vehicles for winter aviation operations. Their core function is to remove frost, snow, and ice from the aircraft surface by spraying heated de-icing fluid to ensure flight safety. These vehicles are usually equipped with hydraulic lifting arms, which can raise the nozzles to a position above the fuselage to perform precise de-icing operations on critical parts such as wings, tail, and landing gear.

[0004] Therefore, it is necessary to design a de-icing fluid heating device to ensure that the de-icing fluid has a sufficient temperature. Utility Model Content

One end of the heat-conducting column 4 is arranged in the liquid inlet chamber and the other end is arranged in the cavity 101. A spacer tube 5 is connected between the coils. A filter screen 6 is covered at the flue outlet 105. An elastic quick-release mechanism 7 is arranged between the filter screen 6 and the flue outlet 105 and detachably connects the filter screen 6 to the flue outlet 105.

[0028] In some embodiments of this application, the outer side of the cylinder is covered with an insulation layer 106, the insulation layer material is aerogel felt, and the outer side of the insulation layer is covered with a stainless steel outer skin.

[0029] In some embodiments of this application, the cylinder further includes: a cylinder body, a left end cap, and a right end cap. The right end cap is connected to the right end of the cylinder body, and the left end cap is connected to the left end of the cylinder body (based on the direction shown in the figure). The interface 102 is configured on the left end cap, and a burner is installed on the interface 102. The burner is an existing product and can be purchased directly. The left end cap has a through hole corresponding to the burner's nozzle that communicates with the cavity 101.

[0030] In some embodiments of this application, the heater further includes a support leg 8, which is connected to the lower end of the cylinder body and is used to fix the heater to the airport de-icing equipment.

[0031] In some embodiments of this application, the housing 1 further includes a second drain port 107, which is connected to the housing 1 and is used to drain condensate. The condensate in the housing 1 can be drained through the second drain port 107 to prevent condensate from accumulating in the housing 1 and to improve the usability of the heater.

[0032] In some embodiments of this application, the coil assembly 3 has at least three layers of coils in the radial direction, the coils are spiral in the axial direction, the cavity 101 is provided with a positioning boss 108, the innermost coil is fitted onto the positioning boss 108, and the outermost coil is fitted onto the inner partition 2. The water output of the heater is increased by the at least three layers of coils, and the positioning boss 108, the inner partition 2 and the spacer tube 5 work together to limit the position, thereby improving the positioning stability of the coil assembly 3.

[0033] In some embodiments of this application, adjacent coils are positioned by spacer tubes 5. Spacer tubes 5 are provided at both ends of the coils. The spacer tubes 5 are evenly distributed on the circumference with the central axis of the coil group 3 as the center line. The spacer tubes 5 maintain the stability of the coil group 3 structure.

[0034] In some embodiments of this application, the elastic quick-release mechanism 7 includes: a base 701, a ball 702, and an elastic element 703. The base 701 is installed at the flue opening 105, the ball 702 is slidably disposed in the base 701, and the elastic element 703 is disposed between the ball 702 and the base 701. The filter body 6 has a positioning hole 601 corresponding to the ball 702. The ball 702 and the elastic element 703 form a positioning structure for the filter body 6, which can realize the quick-release and quick-installation function of the filter body 6.

[0035] In some embodiments of this application, at least four sets of elastic quick-release mechanisms 7 are provided. Each set of elastic quick-release mechanisms 7 is positioned at the same height around the inner wall of the flue opening 105. The seat 701 includes a seat body and a cover plate. A slide rail is provided on the seat body, and a ball 702 is disposed in the slide rail and can move left and right along the slide rail. One end of the seat body is connected to the inner wall of the flue opening 105, and the other end is connected to the cover plate. A positioning post extends from the cover plate towards the slide rail. The elastic body is a cylindrical compression spring (referred to as a compression spring). One end of the compression spring is fitted onto the outside of the positioning post, and the other end contacts the ball 702 and applies pressure to the ball 702 towards its back. The external force moving away from the cover plate causes the flue opening 105 to have a limiting hole. The limiting hole is an arc-shaped through hole that matches the shape of the sphere 702. Part of the structure of the sphere 702 can extend to the outside of the flue opening 105 through the limiting hole. The filter screen body 6 has a surrounding plate, and the filter screen is connected in the surrounding plate. The surrounding plate has a positioning hole 601, which is an arc-shaped through hole that matches the shape of the sphere 702. The sphere 702 enters the limiting hole and contacts the hole wall of the limiting hole, thereby limiting the filter screen body 6 to a specific position. The filter screen prevents objects from falling into the housing 1 through the flue opening 105.

[0036] In some embodiments of this application, the filter body 6 is equipped with a pointer 602, and the flue vent 105 is equipped with a positioning groove 109. When the ball 702 is inserted into the positioning hole 601, the pointer 602 points to the positioning groove 109, which makes it easy for the filter body 6 to quickly find the installation position.

[0037] In some embodiments of this application, the pointer 602 is connected to the enclosure, and the positioning groove 109 is formed on the outer wall of the flue vent 105.

[0038] When this type of heater is working, the burner is turned on, and the water pump connected by the external pipe draws the de-icing fluid into the inlet 103. The de-icing fluid enters the inlet chamber and flows into the coil. The heat flow sprayed by the burner heats the coil and the heat-conducting column 4, thereby increasing the temperature of the de-icing fluid. The heated de-icing fluid is finally discharged into the de-icing equipment through the drain pipe, thus realizing the function of heating the de-icing fluid.
