Oil heater heat dissipation sheet assembly, corresponding hole port welding device and oil heater warmer

Abstract

The invention provides an oil heater heat dissipation sheet assembly, a corresponding hole port welding device and an oil heater warmer. The oil heater heat dissipation sheet assembly comprises two adjacently-arranged heat dissipation sheet assembly single bodies. Each heat dissipation sheet assembly single body is provided with an oil pocket boss, wherein the oil pocket boss is provided with a circulation hole penetrating in the protruding direction of the oil pocket boss, and the hole port position of the circulation hole is provided with a ring wall extending towards the radial inner side of the circulation hole. The ring walls of the adjacent two heat dissipation sheet assembly single bodies are connected in a circumference seam welding manner. According to the oil heater heat dissipation sheet assembly, the corresponding hole port welding device and the oil heater warmer, the oil pocket bosses of the adjacent two heat dissipation sheet assembly single bodies are connected in a circumference seam welding manner, consistency of the welding quality at the positions of the oil pocket bosses is guaranteed, dotted electrode indentations generated during spot welding do not exist, and solder skips and other welding quality problems are avoided.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation and lubrication of electric spindles, and in particular relates to an oil heat sink assembly, a corresponding orifice welding device, and an oil heat sink heater. Background technique [0002] In the prior art, oil-filled heaters are also known as oil-filled heaters. The surface temperature of the cooling fins is uniform, comfortable to use, dust-free, odor-free, noise-free, and does not emit visible light. The application occasions are flexible and changeable, so they are widely used. use. The heat dissipation body of this oil heater heater is an oil radiator fin assembly, and the oil radiator radiator assembly includes a plurality of radiator assembly monomers with the same structure, and there are air circulation channels between each monomer to form a heat sink in the heater. Efficient heat exchange between heat transfer oil and outside air. Each heat sink assembly unit is formed by...

AI Technical Summary

Problems solved by technology

Each heat sink assembly unit is formed by welding two structurally symmetrical oil sheets. With the advancement of welding technology, in the prior art, the two oil sheet bodies in the heat sink assembly monomer are seamed. The seam welding is realized by the circular seam welding machine. The current circular seam welding machine is generally large in structure and size, and it is mostly set on the outer peripheral side of the workpiece to be welded. The corresponding rotation is realized by controlling the rotation of the workpiece to be welded. The circumferential weld seam, and the welding between the oil-encased bosses of the two adjacent heat sink assemblies is mostly the traditional double-sided spot welding method, because the electrode of the welding device is controlled by the workpiece during double-sided spot welding The two sides of the feed to the welding place, so point-shaped electrode indentations will be generated on both sides of the oil-filled boss, and the adjacent parts will continue to be spot-welded until the spot welding is completed, and a circle of dots will be formed on the boss surface Formed indentation, due to the long-term use of the electrode tip, the surface will produce oxide scales. In the long run, the contact will become a curved surface, and the contact welding will not be able to completely guarantee the flat seal of the circumference, which will lead to poor welding quality, such as weld seams.
