Automotive carpet radiant heating system

Abstract

The invention discloses an automotive carpet radiant heating system. The automotive carpet radiant heating system comprises an automotive carpet, an automobile body floor, an engine cooling system, a flow regulating valve and a plurality of coiled radiators, wherein the engine cooling system comprises an engine, a radiator and a water pump; a water inlet of the water pump is connected to a coolant outlet of the engine through a pipeline, the plurality of coiled radiators are connected in parallel and arranged between the automotive carpet and the automobile body floor, an inlet of the flow regulating valve is connected to a water outlet of the water pump through a pipeline, a first outlet of the flow regulating valve is connected to a water inlet of the radiator through a pipeline, a water outlet of the radiator is connected to a coolant inlet of the engine through a pipeline, a second outlet of the flow regulating valve is connected to water inlets of the plurality of coiled radiators through pipelines, and water outlets of the plurality of coiled radiators are connected to the coolant inlet of the engine through pipelines. By means of the heating system, the temperature of the automotive carpet can be balanced, so that the temperature of the air in a carriage is evenly distributed, and the comfort is improved.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an automobile carpet radiation heating system. Background technique [0002] Car carpet radiant heating is a method of introducing the coolant flowing out of the engine cooling system into the coil radiator installed between the car carpet and the floor of the car body to circulate, heat the entire car carpet, and evenly radiate heat into the cabin through the car carpet. Heating method. Compared with the traditional HVAC heating method, it has the following advantages: (1) The blower, air outlet, and air duct are canceled, which not only eliminates noise, but also reduces power consumption, and also simplifies the volume of the air-conditioning box; (2 )Using the uniform thermal radiation on the surface of the entire car carpet as a heat dissipation source, the heat radiates upward from the bottom to heat the air in the compartment, and the temperature of the car carpet ...

AI Technical Summary

Problems solved by technology

The floor heating radiators in each group are arranged in series, such as the five floor heating radiators described in the specific embodiment section, wherein two of the front row are connected in series, three of the rear row are connected in series, and the front row and the rear row are connected in parallel. The floor heating radiators and the rear floor heating radiators are all connected in series, so the average surface temperature of each floor heating radiator along the coolant flow direction decrease
