Abstract

The invention relates to an oil cooler, specifically to an oil cooler for an electric power system and belongs to the technical field of heat dissipation. The oil cooler consists of a core body and further consists of a left sealing head, a right upper sealing head and a right lower sealing head, wherein the left sealing head is arranged on the left side of the core body; the right lower sealing head is arranged in the right lower direction of the core body; the right upper sealing head is arranged in the right upper direction of the core body; a valve block assembly is arranged between the right upper sealing head and the right lower sealing head; a mounting plate is arranged at the lower end of the core body; a plurality of waist holes are formed in the mounting plate; an oil outlet is formed in the valve block assembly; and an oil inlet is formed in the right upper sealing head. The production of the oil cooler has the characteristics of stable performance, simple structure and good heat dissipation effect.

Description

A kind of oil cooler

Technical field

The present invention relates to a kind of oil cooler, be specifically related to a kind of power system and use oil cooler, belong to the heat dissipation technology field.

Background technology

Oil-water cooler is a kind of oil cooling apparatus that generally uses in the power system, also is applicable to departments such as metallurgy, chemical industry, mine, light industry and heavy industry simultaneously.Utilize this cooler to make to have two kinds of liquid mediums of a fixed difference difference to realize heat exchanges, reduce the oil temperature, guarantee the purpose of the normal operation of power equipment thereby reach, be mainly used in the equipment lubrication oil cooling but, the speed change system oil cooling but, transformer oil cooling etc.Oil-water cooler is pressed installation form, is divided into vertical and horizontal two kinds; Be divided into two kinds of light pipe formula and augmentation of heat transfer tubular types by the cooling tube form.

The oil cooling machine also is Cool oil machine, and according to the refrigeration system principle, the liquid refrigerants of low-temp low-pressure carries out the heat that the heat exchange evaporimeter absorbs oil in the evaporimeter the inside with ambient water; Flash to the gaseous state of low-temp low-pressure, refrigerant temperature is constant in the evaporation process, and the refrigerant of low-temp low-pressure gaseous state enters into compressor; Through compressor compresses, be compressed into the gaseous state of HTHP, get into condenser then; In condenser, carry out heat exchange with indoor medium, the part heat of the gaseous state of HTHP is absorbed by medium, and medium temperature raises; Refrigerant heat release condenser becomes the HTHP liquid state, and the condenser process temperature is constant, gets into expansion valve then and carries out throttling; Throttling is the process of lowering the temperature rapidly, and refrigerant becomes the liquid state of low-temp low-pressure, and the refrigerant after this process enters into evaporimeter again and carries out the heat exchange evaporation; Thereby realize the whole process of refrigeration system, this circulation is carried out continuously, and oil just is able to continuously freeze.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, a kind of simple in structure, thermal diffusivity good, cost is low oil cooler is provided.

According to technical scheme provided by the invention; A kind of oil cooler comprises core body, also comprises left end socket, upper right end socket, bottom right end socket; Left side end socket is installed on the core body left side; The bottom right end socket is installed on the core body lower right, and upper right end socket is installed on the core body upper right side, in the middle of upper right end socket and bottom right end socket, is provided with the valve block assembly.

Said core body lower end is provided with installing plate, and installing plate is provided with several lumbar hole.

Said valve block assembly is provided with the pressure by-passing valve.

Said upper right end socket is provided with air inlet.

Said core body is provided with label.

Said left end socket, upper right end socket, bottom right end socket and valve block assembly are fixed through bolt and core body.

Said oil cooler lower end also is provided with two mounting brackets.

The present invention has following advantage: the present invention is provided with the valve block assembly in the middle of upper right end socket and bottom right end socket; Compressed air gets into oil cooler from air inlet; Pressure by-passing valve through on the valve block assembly is regulated compressed-air actuated pressure; It is rationally fixing that mounting bracket makes that core body obtains, and left end socket, upper right end socket, bottom right end socket and valve block assembly seal core body, more help heat radiation.Properties of product of the present invention are stable, and are simple in structure, good heat dissipation effect.

The specific embodiment

Shown in Fig. 1-4; A kind of oil cooler comprises core body 2, also comprises left end socket 1, upper right end socket 6, bottom right end socket 4; Left side end socket 1 is installed on core body 2 left sides; Bottom right end socket 4 is installed on core body 2 lower rights, and upper right end socket 6 is installed on core body 2 upper right side, at upper right end socket 6 and the bottom right end socket 4 middle valve block assemblies 5 that are provided with.

Said core body 2 lower ends are provided with installing plate 7, and installing plate 7 is provided with several lumbar hole 8.Said valve block assembly is provided with air inlet 10.Said upper right end socket 6 is provided with pressure by-passing valve 9.Said core body 2 is provided with label 11.Said left end socket 1, upper right end socket 6, bottom right end socket 4 and valve block assembly 5 are fixed through bolt and core body 2.Said oil cooler lower end also is provided with two mounting brackets 3.

When the present invention works; Compressed air gets into oil cooler from air inlet 10; Regulate compressed-air actuated pressure through the pressure by-passing valve on the valve block assembly 59; It is fixing that mounting bracket 3 makes that core body obtains rationally, and left end socket 1, upper right end socket 6, bottom right end socket 4 and valve block assembly 5 more help heat radiation with the core body sealing.
