Lubricating oil cooler

A technology of cooler and lubricating oil, which can be applied to machines/engines, parts of pumping devices for elastic fluids, and parts of rotary piston type/oscillating piston type pumps, etc., which can solve the problem of large occupied space and manufacturing cost. The problems of high pressure and the overall size of the vacuum pump are increased, so as to reduce the overall size, reduce the manufacturing cost, and facilitate the installation and layout.

Example Embodiment

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0014] In this embodiment, as figure 1 As shown, the lubricating oil cooler includes: a core 1 and a fixing seat 2. The core 1 and the fixing seat 2 are both arc-shaped, and the core 1 and the fixing seat 2 are connected together by argon arc welding.

[0015] Such as image 3 As shown, the core 1 is formed by brazing the upper cover 3, the partition 4, the outer fins 5, the inner fins 6, the inner seal 7, the outer seal 8, and the lower cover 9, on the upper cover 3. Inner fins 6 and outer fins 5 are alternately distributed in parallel with the lower cover plate 9, the inner fins 6 and outer fins 5 are the main heat dissipation elements; the upper cover plate 3, the lower cov...

Abstract

The invention discloses a lubricating oil cooler, which comprises a core body (1) and a fixed seat (2), wherein both the core body (1) and the fixed seat (2) are arc-shaped, and the core body (1) and the fixed seat (2) are welded together. The lubricating oil cooler overcomes the defects of high manufacturing cost, large volume and inconvenience for arrangement in the prior art, realizes the advantages of low manufacturing cost and small volume, and is favorable for installation and arrangement.

Description

technical field [0001] The invention relates to a lubricating oil cooler, in particular to the vacuum pump industry. technical background [0002] Generally, the lubricating oil cooler used on the rotary vane vacuum pump is a rectangular cooler, which is welded by three cores and a fixed seat. The overall size of the vacuum pump is increased, which is not conducive to installation and layout. Contents of the invention [0003] The purpose of the present invention is to provide a lubricating oil cooler which has the advantages of low manufacturing cost, small size and convenient arrangement, aiming at the disadvantages of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a lubricating oil cooler comprising: a core body 1 and a fixed seat 2, the core body 1 and the fixed seat 2 are both arc-shaped, and the core body 1 and the fixed seat 2 welded together. [0005] Further, the core body 1 includes: an...
