Further, described hydraulic oil cooler 1 used material is an aluminium alloy, is that material is that the material cost is low with the copper alloy with the aluminium alloy;

Further, described water radiator 2 used materials are aluminium alloy, are that material is that the material cost is low with the copper alloy with the aluminium alloy;

Further, described torque converter oil cooler 3 used materials are aluminium alloy, are that material is that the material cost is low with the copper alloy with the aluminium alloy;

Further, be respectively equipped with a hanger 9 on the opposing sidewalls of described steel frame 4, be provided with two installation feet 10 symmetrically in the bottom of described steel frame 4, hanger 9 and installation foot 10 are used for installing with main frame.

Further, described combination exchanger, also comprise and add water assembly, the described water assembly that adds comprises compound tank lid 7, steam fairlead 8 and discharging valve 11, described steam fairlead (8) is arranged on compound tank lid (7) one sides, and be arranged at the top of water radiator 2, and compound tank lid 7 is used to add water, and steam fairlead 8 is used to discharge superheated steam; Described discharging valve 11 is arranged at the bottom of water radiator 2, is used for discharging water in case of necessity.

The beneficial effects of the utility model:

A kind of combination exchanger is changed system into a combination exchanger by the heat exchanger that three independently are installed separately, and whole machine installation is arranged more convenient; Make cooling element with aluminium alloy, product cost can reduce 20-30% with the copper alloy preparation; Replace the recirculated water cooling with engine blower cooling, because of cooling medium air and thermal medium hydraulic pressure oil and the oily temperature difference increasing of torque-converters, but the cooling effect of device, torque converter oil cooler is better to make hydraulic oil.

In sum, the utlity model has simple installation, take up room little, cost is low, the advantage of good cooling results.
