Universal cooler for efficiently removing oily water

Abstract

The invention provides a universal cooler for efficiently removing oily water, and belongs to the technical field of refrigeration equipment. The problems that an existing cooler is poor in cooling performance and pressure resistance are solved. The universal cooler for efficiently removing oily water comprises two oil chambers and a core body located between the two oil chambers, the core body comprises a plurality of cooling pipes, two long strip-shaped cooling fins are arranged between ever two adjacent cooling pipes, the cooling fins comprise a plurality of inclined sections and bent portions, the inclined sections are crossed, clamped and positioned, the two opposite side faces of the cooling pipes are provided with a plurality of first positioning grooves, the bent portions of the cooling fins are concaved inwards to form a plurality of flat and straight heat exchange portions, a positioning portion is formed between every two adjacent heat exchange portions, the positioning portions are embedded into the first positioning grooves and welded and fixedly connected to the inner walls of the first positioning grooves, and the outer side faces of the heat exchange portions are infit with the side faces of the cooling pipes in a pressing mode. The universal cooler for efficiently removing oily water has high cooling performance and pressure resistance.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and relates to a high-efficiency decontamination oil-water universal radiator. Background technique [0002] The oil radiator is a device that exchanges heat between the hydraulic oil and the cooling air flow. It mainly includes two oil chambers and a core between the oil chambers. The core has a heat dissipation pipe connecting the two oil chambers and heats the heat dissipation pipe The heat sink, such as the aluminum heat sink disclosed in the patent document (application number: 201520003905.4), includes the core body assembly, the first oil chamber assembly and the second oil chamber assembly, the first oil chamber assembly and the second oil chamber The assemblies are respectively arranged on both sides of the core body assembly, and the upper and lower sides of the core body assembly are respectively provided with cover plates. The first oil chamber assembly communicates wi...

[0002] The oil radiator is a device that exchanges heat between the hydraulic oil and the cooling air flow. It mainly includes two oil chambers and a core between the oil chambers. The heat sink, such as the aluminum heat sink disclosed in the patent document (application number: 201520003905.4), includes the core body assembly, the first oil chamber assembly and the second oil chamber assembly, the first oil chamber assembly and the second oil chamber The assemblies are respectively arranged on both sides of the core body assembly, and the upper and lower sides of the core body assembly are respectively provided with cover plates. The first oil chamber assembly communicates with the second oil chamber assembly through the core body assembly; the core body assembly It consists of a number of outer fins, short seals and heat dissipation tubes that are brazed together from top to bottom. The outer fins are evenly brazed on the outside of the heat dissipation tube along the axial direction of the heat dissipation tube. Short seals, the short seals are fixed on the outside of the heat dissipation pipe; the lower part of the first oil chamber assembly is provided with an oil inlet pipe port, and the lower part of the second oil chamber assembly is provided with an oil outlet pipe port to dissipate heat when the oil passes through the heat pipe. During the process, the core body will be under the pressure of the airflow, and of course it may also be hit by other foreign objects, while the heat sink is only in welding contact with the side of the heat pipe through the bending position, and the heat transfer efficiency between the heat sink and the heat pipe is low, resulting in heat dissipation. Lower performance and less reliable connections to the heat sink, resulting in lower voltage withstand performance
