Semiconductor parking heater capable of achieving thermoelectric power generation

Abstract

The invention provides an efficient semiconductor parking heater capable of achieving thermoelectric power generation. The semiconductor parking heater capable of achieving thermoelectric power generation comprises a parking heater body and a thermoelectric power generation device. The parking heater body comprises an engine warm air water outlet connecting water inlet pipe (1), an engine warm air water return opening connecting water return pipe (12), other pipelines (11), a pipeline heat insulation material, a cylindrical semiconductor heating piece (10), a two-position three-way electromagnetic reversing valve (5), a water pump (6), temperature sensors (3) and (7), an automobile warm air system, a storage battery (14) and a parking heater controller. The thermoelectric power generation device comprises a semiconductor power generation piece, namely a semiconductor heating piece (10), semiconductor heating piece cold face radiating plates (2), a thermoelectric power generation controller and a rectifier (13). According to the semiconductor parking heater capable of achieving thermoelectric power generation, when an automobile engine is not started, the electric quantity of the storage battery of the automobile is used for preheating engine cooling liquid and a cab, and therefore the problems that a traditional fuel parking heater is large in size, low in heat efficiency, excessively large in oil consumption, insufficient in combustion and likely to pollute the environment are solved; and when the engine is started, the cylindrical semiconductor heating piece stops the heating function, the power generation effect starts to be played, thermoelectric power generation can be conducted through the temperature difference between the cooling liquid and an engine compartment, and energy is sufficiently utilized.

Description

technical field [0001] The invention relates to the field of vehicle heating equipment and a vehicle power generation system, in particular to a parking heater and a vehicle thermoelectric power generation device. Background technique [0002] The parking heater is a product that heats the circulating water of the engine so that the engine can be started hot and at the same time warms up the cab. Without starting the engine, the engine and the interior of the car can be preheated in advance at the same time, avoiding the wear and tear on the engine caused by low-temperature cold start, so that the owner can feel the warmth when opening the door in cold winter, and it can also solve the problem of window defrosting and snow scraping , The trouble of wiping the fog. This product has a good market prospect, especially suitable for cold regions. Traditional parking heaters burn gasoline, diesel and other fuels to preheat and heat the engine and the interior of the car, but the...
