    • A total cooling assembly adapted for installation in an engine compartment of an I.C. engine vehicle. The assembly includes a heat exchanger module to transfer heat from fluid coolant to air entering the air flow path and having front and rear faces such that air can pass in heat exchange relation across the heat exchanger module to absorb heat from fluid coolant flowing through the heat exchanger module. The heat exchanger module includes an inlet and an outlet. A cooling fan module carries the heat exchanger module and includes a fan and an electric fan motor for drawing air across the heat exchanger module from the front face to the rear face of the heat exchanger module. Pump structure is carried by the cooling fan module to circulate fluid coolant. The pump structure has at least one pump and an electric motor driving the pump. A cooling circuit is provided in which fluid coolant is circulated by the action of the pump structure. The cooling circuit permits the fluid coolant to move from the pump structure to the engine. An outlet of the engine is constructed and arranged to communicate fluid coolant with the inlet to the heat exchanger module. The outlet of the heat exchanger module is fluidly connected with an inlet to the pump structure to return the fluid coolant to the pump structure. The cooling circuit includes bypass structure constructed and arranged to fluidly connect an outlet of the engine with an inlet to the pump structure. Valve structure is provided in the cooling circuit to regulate flow therethrough. A controller controls operation of the at least one electric motor of the pump structure, the electric fan motor, and the valve structure. During a warm-up operating condition of the engine, the bypass structure permits fluid coolant to flow from the outlet of the engine to the inlet of the pump structure while substantially preventing fluid coolant to flow through the heat exchanger module.
    • 一个总冷却组件,适用于安装在一个I.C.的发动机室中。 发动机车。 该组件包括热交换器模块,用于将热量从流体冷却剂传递到进入空气流动路径的空气,并且具有前表面和后表面,使得空气可以跨热交换器模块传递热交换关系,以吸收流过热量的流体冷却剂的热量 交换机模块。 热交换器模块包括入口和出口。 冷却风扇模块承载热交换器模块,并且包括风扇和电风扇电动机,用于从热交换器模块的前表面向后表面吸引空气穿过热交换器模块。 泵结构由冷却风扇模块承载,以循环流体冷却液。 泵结构具有至少一个泵和驱动该泵的电动马达。 提供了一种冷却回路,其中流体冷却剂通过泵结构的作用而循环。 冷却回路允许流体冷却剂从泵结构移动到发动机。 发动机的出口被构造和布置成使流体冷却剂与热交换器模块的入口相通。 热交换器模块的出口与泵结构的入口流体连接,以将流体冷却剂返回到泵结构。 冷却回路包括构造和布置成将发动机的出口与泵结构的入口流体连接的旁路结构。 阀门结构设置在冷却回路中以调节流过其中的流量。 控制器控制泵结构的至少一个电动机,电风扇电动机和阀结构的操作。 在发动机的预热操作状态期间,旁路结构允许流体冷却剂从发动机的出口流到泵结构的入口,同时基本上防止流体冷却剂流过热交换器模块。
