Abstract

The invention discloses an oil and water combined heat exchanger, which comprises a core (1), an end enclosure (2), an end enclosure (3), an end enclosure (4) and an end enclosure (5). The core (1) is formed by integrally soldering an aluminum plate fin type water radiator core (11) and a aluminum plate fin type hydraulic oil cooler core (12); the end enclosure (2) and the end enclosure (3) are welded at the upper end and the lower end of the aluminum plate fin type hydraulic oil cooler core (12) respectively; and the end enclosure (4) and the end enclosure (5) are welded at the upper end and the lower end of the aluminum plate fin type water radiator core (11) respectively. The oil and water combined aluminum heat exchanger manufactured through the technical scheme reduces the axial size of a combined heat exchanger, is convenient for installation, and saves the installation time.

Description

technical field [0001] The invention relates to an oil-water combined heat exchanger, which is a combined heat exchanger composed of a water radiator and a hydraulic oil cooler. Background technique [0002] Most of the heat exchangers used on small construction machinery are copper tube fin water radiators and copper tube aluminum fin hydraulic oil coolers, both of which are assembled separately in front of the engine by two independent assemblies, oil and The structure of the two water heat exchangers is different, and the front and back need to be installed separately. The disadvantages of the prior art are that the manufacturing cost of the product is high, the axial dimension is relatively large, and the installation and arrangement are inconvenient. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a heat exchanger with compact structure, lower cost and higher heat transfer efficiency. [0004] In order to solve th...
