Oil chamber for oil cooler

Abstract

The invention provides an oil chamber for an oil cooler. The oil chamber comprises an oil chamber body which comprises an oil chamber upper portion and an oil chamber lower portion, the oil chamber lower portion is circular-arc-shaped and is parallelly provided with assembly grooves axially, the assembly grooves are matched with one ends of heat radiating pipes of the oil cooler, and interval and size of the assembly grooves are set according to those of the heat radiating pipes. The lower portion, needing to bearing maximum pressure, of the oil chamber body is arranged to be circular-arc-shaped and integrally formed with the oil chamber body, so that welding of the heat radiating pipes is enabled to be easier. The oil chamber is simple in structure and convenient to assemble and replace, a joint and the oil chamber body are avoided forming sharp corners, the problem of tearing of positions where the oil chamber is welded with the heat radiating pipes due to the fact that the oil chamber deforms during high-intensity running of the oil cooler is solved, and durability of the oil cooler is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery hydraulic oil coolers, in particular to a component for the oil cooler. Background technique [0002] The oil cooler is mainly used in the circuit of the hydraulic system. When working, the high-temperature oil in the hydraulic system flows through the hydraulic oil cooler device, and performs high-efficiency heat exchange with the forced-flowing cold air in the oil cooler to reduce the oil temperature to the working temperature to ensure that the main engine can continue to operate normally and make the work able to proceed smoothly. Due to the increasing use of construction machinery and equipment, the requirements for the performance of oil coolers are also increasing. [0003] As an important part of the oil cooler, the oil chamber plays a very critical role in the oil cooling process. The oil chambers of the current oil coolers for construction machinery are mostly designed as square or...

Problems solved by technology

[0003] As an important part of the oil cooler, the oil chamber plays a very critical role in the oil cooling process. The oil chambers of the current oil coolers for construction machinery are mostly designed as square or D-shaped. When the equipment is performing high-intensity operations , the inside of the oil cooler will be under a lot of pressure, and the oil chamber will be deformed at this time, which will cause the welded part of the oil chamber and the cooling pipe to be torn and cause leakage

CN201420166620.8 Chinese patent discloses a high-strength oil chamber for oil coolers, which overcomes the shortcomings of rectangular profiles to a certain extent, but its lower end is still flat. When the oil chamber is subjected to excessive pressure, it will still cause the oil chamber to Deformation occurs, resulting in oil leakage inside the oil chamber
