Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation equipment for pure electric buses, and in particular to a sealing device for an air guide cover of a heat dissipation water tank. Background Art

[0002] At present, many pure electric bus cooling water tanks do not have sealing devices, and most of the cooling water tanks (ATS) of pure electric buses adopt the suction type cooling method. The air is sucked into the fan through the cooling grille of the water tank hatch. The fan transfers the heat in the cooling water tank to the air. The hot air cannot be completely dissipated outside the vehicle, causing the temperature of the rear battery high-pressure compartment to be too high.

[0003] In the early stage, some pure electric buses adopted sealing by welding and gluing. Although it can completely isolate the heat and the heat will be transmitted outside the vehicle, the obvious disadvantage is that the cooling water tank (ATS) cannot be disassembled for maintenance in the later stage. This method has not been adopted in recent years.

[0004] Some pure electric buses are manufactured with an integral radiator air guide cover. Although this solves the maintenance and disassembly problem, it will reduce the air intake for the ATS, which is not conducive to the heat dissipation of the ATS. Summary of the invention

[0008] Furthermore, keel sealing strips are provided on all four sides of the square opening on the water tank side, which are used to seal the split air guide cover assembly with the water tank compartment to prevent hot air from entering the high-pressure compartment.

[0009] Furthermore, the cross section of the top sealing plate is a U-shaped bent plate with an opening facing downward, and the bent edge on the water tank side is longer than the outer bent edge, and the outer bent edge is riveted to the hatch frame by closed rivets.

[0010] Furthermore, a bubble sealing strip is provided at the end of the outer bent edge, with the bubbles facing the water tank door, for sealing the split air guide cover assembly and the water tank door.

[0011] Furthermore, the cross-sections of the front and rear side sealing plates are both L-shaped bent plates, and the L-shapes of the front and rear side sealing plates are symmetrically arranged facing each other.

[0012] Furthermore, the bottom sealing plate includes a bending plate and a sealing head. The longitudinal section of the bending plate is a U-shape with the opening facing upward, and the sealing head is fixedly connected to the inner end surface of the bending plate.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.
