Problems solved by technology

In this way, due to the setting of 76 degrees, the engine water temperature will be too low during non-long downhill, resulting in increased fuel consumption and worsened emissions
The disadvantages of the existing retarder thermostat scheme, in addition to the lowering of the engine operating temperature, is not conducive to the energy saving and emission reduction of the engine; in addition, due to the poor sensitivity of the traditional wax-type thermostat, when the retarder intervenes, it cannot Rapidly increasing the flow rate of the large cycle, the retarder has to take measures to limit the braking torque to adapt to the sensitivity of the thermostat, thus limiting the function of the retarder at the initial stage of braking

Abstract

The invention discloses a retarder cooling system. The retarder cooling system comprises a radiator, an engine, a transmission, a water pump, a retarder, a heat exchanger and a temperature regulator with a first chamber and a second chamber, the first chamber is provided with a cooling water inlet and a cooling water outlet, the second chamber is provided with a hot water inlet, a big circulation port and a small circulation port, the first chamber is communicated with the second chamber through a connecting tube, and a first valve for controlling the opening or closing of the connecting tube and the like are arranged in the first chamber. Not only is the structure of the retarder cooling system simple and small, but also the action of the retarder cooling system is linked with the retarder, and thereby the retarder can be rapidly cooled.

Description

technical field [0001] The invention relates to the technical field of retarder cooling, in particular to a retarder cooling system. Background technique [0002] The hydraulic retarder is activated by the operating handle. During the working period, the heating power is as high as 200-600 kilowatts. It needs to dissipate heat quickly. The oil temperature should be controlled below 160 degrees to avoid oil deterioration. The main route of its traditional cooling cycle is: engine water outlet - retarder heat exchanger - thermostat - large circulation (radiator) / small circulation - water pump - engine water inlet, the core of this scheme is The traditional wax-type thermostat connects the engine cooling system with the main channel of the retarder heat exchanger. In order to prevent the oil overheating problem of the retarder, that is, to solve the problem of rapid heat dissipation of the retarder, while increasing the flow rate of the thermostat, the initial opening temper...
