Abstract

The invention discloses an adjustable independent heat dissipation device of a loader-digger. A cooling assembly (1) is arranged on a belt wheel end of an engine (5), a hydraulic pump (4) is connected with the engine (5), one oil port of the hydraulic pump (4) is connected with a hydraulic oil tank through an oil suction pipe (7), the other oil port of the hydraulic pump (4) is connected with an electromagnetic proportional overflow valve (2) through an oil pipe, the electromagnetic proportional overflow valve (2) is connected with the hydraulic oil tank through an oil return pipe (6), the electromagnetic proportional overflow valve (2) is connected with a motor (8) through an oil pipe, a temperature sensor is mounted on a radiator, and the temperature sensor and the electromagnetic proportional overflow valve (2) are electrically connected with a heat management system controller. The adjustable independent heat dissipation device of the loader-digger has the advantages that a fan is not directly driven through an engine any longer, the heat management system controller analyzes real-time data of the radiator detected by the temperature sensor, the purpose of controlling the rotating speed of the fan according to the temperature of the radiator is achieved by controlling the oil mass through the electromagnetic proportional overflow valve, oil consumption is lowered, and noise is reduced.

Description

The adjustable independent heat abstractor of a kind of loader-digger
Technical field
The present invention relates to the adjustable independent heat abstractor of a kind of loader-digger, belong to heat sink technology field.
Background technology
In order to meet the need of market, loader-digger requires more and more higher aspect energy-conservation, noise reduction, system radiating, particularly the affect aspect of each system radiating on overall performance.The cooling dependence motor of traditional loader-digger hydraulic system, transmission system, engine system drives fan to lower the temperature to radiator by belt, though reduced to a certain extent the temperature of each system, but the direct drive fan of motor, rotation speed of the fan changes with engine speed, cannot change and adjust rotating speed according to radiator temperature, power consumption is large, and noise is high, and environmental suitability is poor.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides the adjustable independent heat abstractor of a kind of loader-digger, can regulate rotation speed of the fan according to radiator temperature, the effect that reach energy-conservation when effectively controlling temperature, reduces noise.
To achieve these goals, the technical solution used in the present invention is: the adjustable independent heat abstractor of a kind of loader-digger, comprise cooling unit, cooling unit is placed on the pulley end of motor, also comprise electromagnetic proportion relief valve, hydraulic pump, heat management system controller and temperature pick up, hydraulic pump is connected with motor, a hydraulic fluid port of hydraulic pump is connected with hydraulic oil container by fuel sucking pipe, another hydraulic fluid port of hydraulic pump is connected with electromagnetic proportion relief valve by oil pipe, electromagnetic proportion relief valve is connected with hydraulic oil container by oil return pipe, electromagnetic proportion relief valve is connected with motor by oil pipe, temperature pick up is arranged on radiator, temperature pick up and electromagnetic proportion relief valve are electrically connected to heat management system controller.
Further, also comprise high pressure filter, hydraulic fluid port of high pressure filter is connected with hydraulic pump, and a hydraulic fluid port is connected with electromagnetic proportion relief valve.
Further, temperature pick up has three, is arranged on respectively on water radiator, hydraulic oil radiator and torque-converters radiator.
The invention has the beneficial effects as follows: fan is no longer directly driven by motor, the radiator real time data that heat management system controller analysis temperature sensor detects, thereby by electromagnetic proportion relief valve, control oil mass and control motor rotary speed, reach the object of controlling rotation speed of the fan according to radiator temperature, therefore better save oil consumption, reduced noise.
