It is provided with stiffening plate copper foil in the both ends of lower cover plate top surface, between lower cover plate and stiffening plate, stud, lower cover are provided on lower cover plate
After the both ends setting stiffening plate of plate, the both ends intensity of lower cover plate is improved, and anti-twisting property is stronger, sets between lower cover plate and stiffening plate
Stiffening plate copper foil is set for better fixed lower cover plate and stiffening plate, stud is set on lower cover plate, facilitate later period lower cover plate and
The connection of other component.
Further, by being welded to connect, stud and lower cover plate pass through welded connecting and can guarantee that connection is strong for stud and lower cover plate
Degree.
Further, stud and stiffening plate are located at the same face of lower cover plate, are provided at least two studs, stud on lower cover plate
Between two stiffening plates, at least two studs are arranged on lower cover plate can guarantee the stability of connection, and stud number
More, the power that each stud is shared is smaller.
Further, stiffening plate is welded to connect with lower cover plate by stiffening plate copper foil, is first used a little between stiffening plate and lower cover plate
Weldering pre-fixes, and prevents from moving, solder of the stiffening plate copper foil as vacuum welding between stiffening plate and lower cover plate, will be added with vacuum welding
Strong plate and lower cover plate link together, and guarantee that there is no gaps to influence bonding strength for junction.
Further, lower cover plate includes bottom plate and side plate, and bottom plate is an integral molding structure with side plate, base plate thickness be 0.8~
The integrated molding of 1.5mm, bottom plate and side plate can guarantee reliability, and integrally formed structure facilitates manufacture, removes the later period from
The cost of welding, the thickness control of bottom plate under control when the weight of cover board, and can guarantee lower cover at 0.8 millimeter to 1.5 millimeters
The rigidity of plate.
Further, side plate is located at the bottom edge of bottom plate, and side plate is in enclosed construction, and side plate is located at bottom edge and can add
Strong whole structural strength and resistant to bending ability.
Further, stiffening plate is with a thickness of 1~2.5mm, and the thickness of stiffening plate is at 1 millimeter to 2.5 millimeters, the both ends of lower cover plate
Stiffening plate more more complicated than stress condition elsewhere, that 1 millimeter to 2.5 millimeters of extra soldered, strengthening, lower cover board ends are strong
In the case where degree, the whole weight of stiffening plate 1 will not influence.
The utility model is by adopting the above-described technical solution, have the advantages that
The utility model of simple structure and strong practicability is prevented by the way that stiffening plate is arranged in plate heat exchanger lower cover board ends
Plate heat exchanger lower cover board ends cause to deform since intensity is inadequate, by the way that spiral shell is arranged in plate heat exchanger lower cover plate bottom surface
Column facilitates the connection of lower cover plate and other component.
