Description
Technical field
The utility model is a kind of double-tube type heat regenerator, it is characterized in that double-tube type heat regenerator by inner tube, outer tube,
Water inlet pipe, outlet pipe and drainpipe composition, heat regenerator are connected in the exhaust pipe of engine, and engine exhaust is directly from inner tube
By, engine coolant from water inlet pipe enter inner and outer tubes between cavity, flowed out from outlet pipe, heated cooling
Liquid is heated to driver's cabin and engine, improves comfortableness, reduces discharge of poisonous waste, and when engine water temperature is sufficiently high, heat is returned
Valve to be received to close water inlet pipe and outlet pipe, drainpipe is opened, and the heat of engine exhaust vaporizes the coolant in heat regenerator,
Drainpipe at the minimum position of heat regenerator, on heat regenerator cavity top assemble by steam, and pressure caused by steam is by coolant
Without heat recovery function is lost after coolant inside drainpipe push-in expansion tank, heat regenerator, the heat of engine exhaust is avoided
Amount excessively recovery makes engine overheat.
Background technology
Engine fuel burning caused by heat about 30% fall with discharge loss, this partial heat recovery always with
All not obtain the attention of automobile factory, although heat recovery principle is very simple, it is only necessary to which a simple heat exchanger can
With by the heat recovery of engine exhaust, but the heat effect reclaimed is very limited, is exactly to be used for heating driver's cabin nothing but, improves
Comfortableness, increase the cost of hundreds of members for main engine plants and can only be used for driver's cabin and heat, not as good as with using electrical heating empty
Adjust and calculate, recovery more so heat, which increases a set of heat recovery system, loses more than gain, so still because the high effect of cost is small
Reason is rejected, and as environmental regulation is more and more tighter, especially hybrid power engine is gradually popularized, and each automobile factory is gradually right
Engine exhaust heat recovery starts to pay attention to, and the heat of recovery can not only heat driver's cabin, can allow hair with heated engine
Motivation reaches optimum Working with the most short time, it is possible to reduce discharge of poisonous waste, so a kind of i.e. safety can be found
The reliable cheap heat regenerator of cost again is the key that can technique be popularized.
Purpose of utility model and advantage
The utility model is a kind of double-tube type heat regenerator, it is characterized in that double-tube type heat regenerator by inner tube, outer tube,
Water inlet pipe, outlet pipe and drainpipe composition, structure are very simply connected to engine exhaust without the part of activity, heat regenerator
Guan Zhong, inner tube are directly connected with the exhaust pipe of engine, and the exhaust of engine is from inner tube by the way that engine coolant is through water inlet pipe
Into the cavity between inner and outer tubes, flowed out after being heated through outlet pipe, the water inlet of heat regenerator is controlled by heat-recovery valve, gone out
Water and draining, when engine water temperature is sufficiently high, heat-recovery valve closes water inlet pipe and outlet pipe, and drainpipe is opened, recuperation of heat
Device is closed, and now also has the coolant necessarily measured in heat regenerator, if serious problems, solution party can be produced by not being discharged
Case is that the heat of engine exhaust gradually makes coolant boiling dull in heat regenerator and vaporization, and drainpipe is in heat regenerator
Minimum position, steam heat regenerator cavity top assemble produce pressure by the coolant in cavity from drainpipe discharge, it is cold
But liquid is extruded into the expansion tank of engine, until the coolant in cavity is all discharged, the coolant in heat regenerator
All after discharge, no coolant takes away heat, loses heat recovery function, avoids heat from causing engine mistake by excessive recovery
Heat, the simple cost of structure of heat regenerator is low, and the heat of recovery makes engine and driver's cabin quick heating, improves in-car comfort level,
Reduce engine discharge of poisonous waste.
Utility model content
A kind of double-tube type heat regenerator of the present utility model (see Fig. 1), it is therefore an objective to optimize heat regenerator structure, be allowed to tie
Structure is simple, cost reduces, it is characterized in that double-tube type heat regenerator is by inner tube (1), outer tube (2), water inlet pipe (3), outlet pipe (4)
Formed with drainpipe (5), the cavity (7) of inner tube (1) and outer tube (2) composition closing, water inlet pipe (3), outlet pipe (4) and draining
Pipe (5) is welded on outer tube (2) and communicated with cavity (7), and engine coolant enters cavity (7) through water inlet pipe (3), from going out
Water pipe (4) flows out, and water inlet pipe (3) and outlet pipe (4) position are higher than drainpipe (5), and drainpipe (5) is in extreme lower position, water inlet pipe
(3) and outlet pipe (4) installation site in discharge directions regardless of front and rear, if the position residing for heat regenerator needs installation to hang
Hook (12), suspension hook (12) can be welded on outer tube (2) (see Fig. 2), and heat regenerator is connected in the exhaust pipe of engine (see figure
5), engine exhaust from inner tube (1) by heating the coolant in heat regenerator, the coolant after heating flows through sky
Heater tank and engine are adjusted, is heated to driver's cabin and engine, improves cab comfort, engine is reached with shorter time
Optimum state, engine discharge of poisonous waste is reduced, when the cooling-water temperature sensor on engine monitors that water temperature is sufficiently high, is started
Machine ECU sends instruction and opens heat-recovery valve I closings, heat-recovery valve II, and the water inlet pipe (3) and outlet pipe (4) of heat regenerator close
Close, drainpipe (5) is opened, and is trapped in coolant in heat exchanger cavity (7) and is continued by the heat of engine exhaust, cold
But liquid vaporizes, and steam assembles generation pressure on heat regenerator cavity (7) top and coolant is pushed into motivation from drainpipe (5)
In expansion tank, last steam also can with drainpipe (5) enter expansion tank in, be cooled into liquid and reclaim, it is unnecessary not
The steam being recovered after coolant emptying, loses heat recovery function, avoids heat out of the stomata discharge on kettle lid, heat regenerator
Amount causes engine overheat by excessive recovery.
According to real needs, inner tube (1) is substituted by heat exchanger fin (6), and such a structure can be called heat exchange chip heat regenerator
(see Fig. 3), multiple heat exchanger fins (6) are stacked together, and engine exhaust flows through from the passage of heat exchanger fin (6) interior sealing, heat exchange
The outside cavity (7) that closing is formed with outer tube (2) of piece (6), coolant enter cavity (7) from water inlet pipe (3), then through outlet pipe
(4) flow out, after heat regenerator is closed, the coolant in cavity (7) is discharged into expansion tank from drainpipe (5), allows heat regenerator to lose
Heat recovery function is gone to avoid engine overheat, heat exchange chip heat regenerator is complicated, and cost is high, but organic efficiency is high, size
In the case of identical, recovery heat is more, and coolant heats up faster.
Second of structure (see Fig. 6) of the outer tube (2) of double-tube type heat regenerator, inner tube (1) and outer tube (2) are all curved
Pipe, bend pipe moulding is advantageous to be arranged in the less region in space, and blast pipe can be wrapped up entirely, plays a part of insulation,
Catalyst converter shorter time can be made to reach firing point initial stage in engine start, reduce discharge of poisonous waste.
The third structure (see Fig. 7) of the outer tube (2) of double-tube type heat regenerator, sometimes due to the limitation of structure, inner tube
(1) and outer tube (2) is bend pipe, and inner tube (1) and outer tube (2) suit technique can not be realized, after outer tube (2) is divided into multistage splicing
Welding, forms the cavity (7) of closing among the outer tube (2) that inner tube (1) and multistage are spliced, and the outer tube (2) of multistage splicing can solve
Certainly packaging technology problem.
