Abstract
The utility model relates to a novel oil gas heat exchanger, which comprises a hydraulic oil cooler and an intercooler, wherein the hydraulic oil cooler is positioned at the lower end of the intercooler and connected through a connection component; the connection component is a rivet; the hydraulic oil cooler is an aluminium-made plate-fin type hydraulic oil cooler, is formed through welding an oil core body and oil seal heads, and is provided with an oil drainage screw plug; the intercooler is an aluminium-made plate-fin type intercooler and is formed through welding a gas core body and gas seal heads; an installation seat is arranged on the hydraulic oil cooler; and installation aluminium angle is arranged on the intercooler. The utility model has the benefits that the aluminium-made plate-fin type intercooler and the aluminium-made plate-fin type hydraulic oil cooler, which are combined and assembled in tandem, are changed to a heat exchanger assembly adopting a vertical assembly manner, thereby shortening the axial dimension of the combined heat exchanger, facilitating the installation and the arrangement, and lowering the total cost by around 20% to 30%.
Description
Technical field
The utility model relates to a kind of novel oil gas heat exchanger, belongs to engineering machinery field, is applied on the excavator.
Background technology
The heat exchanger that uses on excavator is by charge air cooler and hydraulic oil cooler structure, the charge air cooler of prior art is the aluminum plate-fin type charge air cooler, hydraulic oil cooler is the aluminum plate-fin type hydraulic oil cooler, both be by two independently the assembly separate groups be contained in the engine front of excavator, two kinds of heat exchanger structures of hydraulic oil cooler and charge air cooler are different, and need be installed in respectively one in front and one in back, therefore, the product axial dimension is bigger, the mounting arrangements inconvenience, the wind side pressure is fallen bigger, weak effect, product cost height.
The utility model content
In order to address the above problem, the utility model provides a kind of novel oil gas heat exchanger, replace existing aluminum plate-fin type charge air cooler and aluminum plate-fin type hydraulic oil cooler with oil gas split assembling aluminum heat exchanger, change two heat exchangers of front and back assembling into an oil gas heat exchanger of split assembling up and down, dwindled the axial dimension of combination exchanger, make more compact structure, mounting arrangements is more convenient, having reduced the wind side pressure of whole heat exchanger simultaneously falls, help improving radiating effect, reduce product cost.
The technical solution of the utility model is: a kind of novel oil gas heat exchanger, comprise hydraulic oil cooler and charge air cooler, described hydraulic oil cooler is positioned at the charge air cooler lower end, and connect by coupling assembling, the coupling assembling rivet, hydraulic oil cooler is the aluminum plate-fin type hydraulic oil cooler, be welded by wick body and oil sealing head, and be provided with purge cock, charge air cooler is the aluminum plate-fin type charge air cooler, be welded by wick body and oil sealing head, hydraulic oil cooler is provided with mount pad, and charge air cooler is provided with established angle aluminium.
The beneficial effects of the utility model are: the utility model changes the aluminum plate-fin type charge air cooler and the aluminum plate-fin type hydraulic oil cooler of front and back combination assembling into the heat exchanger assembly of assembling up and down, dwindled the axial dimension of combination exchanger, be convenient to mounting arrangements, totle drilling cost is reduced about 20%-30%.
