Description
Technical field
The present invention relates to a kind of cooling circulating device of engine, particularly a kind of engine cooling and circulating system utilizing outlet pipe auxiliary heating.
Background technique
In traditional engine cooling circulation, cooling liquid major cycle and cooling liquid short circle are all set, when coolant temperature is lower, adopt cooling liquid short circle, utilize the endless form rapid temperature increases do not dispelled the heat; When coolant temperature reaches design standard, generally 80 ~ 90 DEG C time, switch cooling liquid major cycle, cooling liquid is dispelled the heat by radiator.When the temperature of the surroundings is low, after engine start, cooling liquid initial temperature is low, and heating is slow, and in car, air-conditioning heating effect is poor, also has impact to engine warm engine efficiency.Present auxiliary heating has fuel oil auxiliary heater and PTC auxiliary heating two kinds, consumes energy larger.And containing higher heat in motor exhaust, directly discharge causes heat loss larger.
Chinese patent CN1687663A discloses a kind of sheath type water heater on end gas tube of automobile engine, by the shell of two ends fall home plane at a right angle with formed by casing motor exhaust tube wall inner casing inside, shell two ends are welded on the offgas duct tube wall that quilt cover, and are connected with offgas duct.Be water tank between shell and offgas duct tube wall inner casing, there is lagging the outside of shell, and the one end below shell is provided with cold water inlet, and the other end is above provided with hot water outlet.During use, the water pipe sleeve of cold water inlet band water pump connects water source, on hot water outlet water pipe sleeve and on the shower nozzle be connected in tent or radiator, pump water inlet of then fetching boiling water, starts motor car engine heating, just can carry out shower or heating.Although this device utilizes engine tail gas waste-heat, but can only use when stopping, and need engine start to dally, cause energy waste, and water jacket and outlet pipe are made of one structure, when not needing heat exchange, the high temperature of tail gas to the water heating evaporation in water jacket, can damage water jacket.
For another example Chinese patent CN2645955Y, CN2551494Y, above-mentioned two patents are a kind of motor exhaust hot-water heating heat-exchanger rig respectively, all adopt the water jacketing heat exchange be fixedly installed on outlet pipe, therefore need to arrange outlet pipe bypass branch, without the need to switching outlet pipe branch road during heat exchange, it is overheated to avoid, and this device needs to do larger change to outlet pipe, is difficult to the exhaust performance ensureing outlet pipe.
Summary of the invention
The object of the invention is to change larger problem for large, the existing tail gas water heating device of existing cooling recirculation system warming-up auxiliary heating power consumption to outlet pipe, providing a kind of to the engine cooling and circulating system that utilize outlet pipe auxiliary heating of outlet pipe without the need to changing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of engine cooling and circulating system utilizing outlet pipe auxiliary heating, comprise the cooling liquid short circle loop being provided with air conditioning warm air core body and the cooling liquid major cycle loop being provided with radiator, the thermostat for switching is provided with between cooling liquid short circle loop and cooling liquid major cycle, tail gas heat exchange module is provided with before the air conditioning warm air core body in described cooling liquid short circle loop, tail gas heat exchange module comprises outlet pipe and the separable armful of water jacket be clipped on outlet pipe, on water jacket, two ends are provided with import and the outlet of cooling liquid.During automobile starting, engine exhaust pipe is the position that the outer temperature of motor is the highest, when coolant temperature is lower, when cooling liquid carries out short circle, water jacket is embraced and is clipped on outlet pipe, the temperature of outlet pipe is utilized to carry out auxiliary heating to cooling liquid, through from water jacket heating cooling liquid now as the part that temperature cooling liquid is the highest, enter air conditioning warm air core body immediately, improve the effect of warm air conditioner in car, make full use of tail gas heat quantity simultaneously, also improve the engine warm engine efficiency under cryogenic conditions.When coolant temperature reaches thermostat requirement, open major cycle, now water jacket is separated with outlet pipe, does not carry out heat exchange, avoids cooling liquid overheated.This device does not need to change outlet pipe, ensure that smooth gas discharge.
As preferably, described water jacket is semilune structure, intrados and outlet pipe outer surface adaptive.Water jacket cross section is semilune structure, can embrace and press from both sides or be separated by transverse shifting with outlet pipe.
As preferably, described water jacket is provided with two in outlet pipe bilateral symmetry, embraces respectively be clipped in outlet pipe from both sides.Make outlet pipe both sides stress equalization.
As preferably, the side that folder embraced by described water jacket and outlet pipe adopts walled metallic structure.Ensure the surface contact of water jacket and outlet pipe, and adopt the metallic material of thin-walled, good heat conductivity.
As preferably, the embracing to press from both sides of described water jacket and outlet pipe adopts thermostat synchronous switching control with being separated.
As preferably, the import of described water jacket and outlet adopt flexible pipe to be connected with cooling liquid short circle loop.
As preferably, described water jacket adopts micromachine to drive and realizes pressing from both sides with embracing of outlet pipe and being separated.
The present invention arranged tail gas heat exchange module before the air conditioning warm air core body in cooling liquid short circle loop, utilized tail gas heat quantity heated cooling fluid, improved warm air conditioner effect, improve engine warm engine efficiency; Water jacket controls to embrace with outlet pipe to press from both sides or discrete by thermostat, avoids cooling liquid overheated.
