Abstract

The utility model relates to a heat exchanger, which comprises a hydraulic oil cooler, a water radiator and a connecting assembly, wherein the hydraulic oil cooler and the water radiator are connected into a whole by the connecting assembly, and the connecting assembly is the combination of bolts, nuts, washers and the like. The technical scheme reduces the axial dimension of the combined heat exchanger and is not only beneficial to installation and arrangement but also saves installation time; two copper heat exchanger products are changed into aluminum products, and thereby, the cost is reduced by about 30 percent.

Description

A kind of heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, especially the combination exchanger of being made up of water radiator and hydraulic oil cooler.

Background technology

The heat exchanger great majority that use on medium-sized engineering machinery are but devices of copper pipe type water radiator and aluminum plate-fin type hydraulic oil, both be by two independently the assembly separate groups be contained in the engine front, oil is different with two kinds of heat exchanger structures of water, and partial installation before and after needing.The shortcoming of prior art is the cost of goods manufactured height, and axial dimension is bigger, the mounting arrangements inconvenience.

The utility model content

Technical problem to be solved in the utility model provides a kind of compact conformation, cost is lower, heat transfer efficiency is higher heat exchanger.

For achieving the above object, the technical scheme that the utility model is taked is:

A kind of heat exchanger comprises hydraulic oil cooler, water radiator, coupling assembling; Described hydraulic oil cooler and water radiator connect as one by coupling assembling, and described coupling assembling is combinations such as screw, nut, packing ring;

Hydraulic oil cooler comprises end socket (2), aluminum plate-fin type hydraulic oil cooler core body and end socket (3), and end socket (2) and end socket (3) are welded on the upper/lower terminal of plate-fin hydraulic oil cooler core body respectively;

Water radiator comprises end socket (5), aluminum plate-fin type water radiator core body and end socket (6), and end socket (5) and end socket (6) are welded on the upper/lower terminal of plate-fin water radiator core body respectively.

Further be improved to, go up the welding filler, compound tank lid and steam fairlead are housed on the filler at end socket (4).On end socket (6), discharging valve is housed.Be welded with oil-in and oil-out respectively on end socket (2) and the end socket (3).

Assemble aluminum heat exchanger assembly by the profit split that this technical scheme is made, replace existing partial installation structure with installation component combined aluminium heat exchanger made, assembly structure is made up in front and back be improved to the axial dimension that the integral solder combining structure has been dwindled combination exchanger, both be convenient to mounting arrangements, saved the set-up time again; Change two kinds of copper heat exchanger products into the aluminum product, cost reduces about 30%.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

Embodiment 1

As shown in Figure 1, after hydraulic oil cooler 1, water radiator 4 processed respectively, with coupling assembling 7 hydraulic oil cooler 1 and water radiator 4 are connected as one, coupling assembling 7 is combinations such as screw, nut, packing ring;

The end socket 2 of hydraulic oil cooler 1 and end socket 3 are welded on the upper and lower part of plate-fin hydraulic oil cooler core body 8 respectively; The end socket 5 of water radiator 4 and end socket 6 are welded on the upper and lower part of plate-fin water radiator core body 9 respectively.

On end socket 4, weld the filler, compound tank lid 10 and steam fairlead 11 are housed on the filler.Discharging valve 12 is housed on end socket 6.Be welded with oil-in 13 and oil-out 14 on end socket 2 and the end socket 3 respectively.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
