The specific embodiment

In order to make those skilled in the art further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, accompanying drawing only provide with reference to and usefulness is described, be not to be used for limiting the utility model.

Fig. 1 is the cross-sectional schematic of the utility model first embodiment.The utility model provides a kind of heat exchange EGR, as shown in Figure 1, comprises a heated body 1, a fluid circuit 2 and a compress cell 3, wherein:

The material of heated body 1 usefulness good heat conductivity is made, and as copper etc., is used for being assemblied in a pyrotoxin 4 (as shown in Figure 3) top.The utility model for embodiment in, heated body 1 comprises a top cover 10 and a base 11.Base 11 be formed with an indent room 110 and with the inlet 111 and outlet 112 of room 110 intercommunications, inlet 111 be the inlet of liquid working fluid 113 when flowing into heated bodies 1, the outlet when outlet 112 is gaseous working fluid 113 discharges.The position of outlet 112 is higher than inlet 111 residing positions.Establish for top cover 10 driving fits lid base 11 tops, and the room 110 by base 11 makes heated body 1 inside be hollow.

Fluid circuit 2 circuitous being looped around outside the heated body 1.On fluid circuit 2, wear a plurality of radiating fins 20 or further install the device that other has refrigerating function additional, as radiator fan (not shown) etc.Fluid circuit 2 has one first port 21 and one second port 22, first port 21 wherein is connected outlet 112 places of heated body 1, after fluid circuit 2 is walked around the periphery of heated body 1, make its second port 22 penetrate and extend in the room 110 of its base 11 by the inlet 111 of heated body 1, make fluid circuit 2 and heated body 1 constitute a circulatory system of sealing, and then at an amount of working fluid 113 of heated body 1 inner injection.

As shown in Figure 1 and Figure 2, feature of the present utility model mainly is to install a compress cell 3 at above-mentioned fluid circuit 2 near second port, 22 places.Compress cell 3 is positioned at heated body 1 inside, can be the crooked body of one " L " font, and has an inlet end 30 and an outlet side 31 that communicates with each other.As shown in Figure 2, when pressure inlet 3 is installed in fluid circuit 2 near behind its second port, 22 places, its outlet side 31 is promptly because of penetrating in the fluid circuit 2 and towards second port 22 of fluid circuit 2, promptly second port 22 of pressure inlet 3 is setting in the same way with second port 22 of fluid circuit 2.The inlet end 30 of compress cell 3 extends outside the fluid circuit 2, and is higher than the surface of the working fluid 113 in the heated body 1 and is positioned at working fluid 113 tops.

By above-mentioned contexture, can obtain heat exchange EGR of the present utility model.

As shown in Figure 3, the utility model in use, be assemblied in heated body 1 on the pyrotoxin 4 and attaching mutually, after pyrotoxin 4 produces heat, the working fluid 113 of heated body 1 inside begins gasification (shown in the solid line arrow) gradually, and rise in the fluid circuit 2 by the outlet 112 of heated body 1, after process fluid circuit 2 outer radiating fin 20 cooling devices such as grade dispel the heat, revert to liquid state (shown in dotted arrow) gradually, and flow to heated body 1 inside by second port 22 of fluid circuit 2 along fluid circuit 2, be used for meeting once more heat and produce phase change and the heat radiation that circulates.

Yet, when the working fluid 113 after pyrotoxin 4 continues to produce heats and gasification presents saturation state in heated body 1 inside, have working fluid 113 behind the partial gasification can be forced to and enter in the compress cell 3 by inlet end 30.At this moment, because the gas pressure and the event of flowing can form a power-assisted that promotes, the liquid working fluid 113 that drives in the fluid circuit 2 flows to second port 22 more quickly and flows into heated body 1 inside, accelerate the flowing velocity of working fluid 113, effectively improved its heat exchanger effectiveness.

The inlet end 30 of compress cell 3 is the wide-mouth shape, and the working fluid 113 after the gasification is more easily entered in the compress cell 3, and second port 22 of fluid circuit 2 is the reducing shape, can quicken the flow velocity of liquid working fluid 113.In order to make liquid working fluid 113 flowing in fluid circuit 2 more smooth and smooth, fluid circuit 2 is beneficial to liquid working fluid 113 inflow heated bodies 1 inside be from top to bottom skewed near one section a outside the inlet 111 of heated body 1.

As Fig. 4, shown in Figure 5, in second embodiment of the present utility model, compress cell 3 comprises an air inlet pipe 3a and a throttle pipe 3b.The end of air inlet pipe 3a is described inlet end 30, and the other end is a link 30a.Offer a through hole 31a in the air inlet pipe 3a, inlet end 30 is connected with link 30a.The end of throttle pipe 3b is described outlet side 31, and the other end is the blind end 30b that caliber dwindles, and blind end 30b locates to offer a connecting hole 31b who connects airtight with the link 30a of air inlet pipe 3a above its side

direction.In throttle pipe

3b, 31 offer a downward-sloping runner 32b to the outlet side, offer a blasthole 33b who communicates with runner 32b on the blind end 30b by connecting hole 31b.

See also Fig. 6, when being installed in compress cell 3 on the fluid circuit 2, open nearly its second port, 22 places at fluid circuit 2 earlier and offer a perforation 220, the link 30a of air inlet pipe 3a is inserted perforation 220, and the blind end 30b of throttle pipe 3b is nested with on second port 22 of fluid circuit 2, and make its connecting hole 31b relative with the perforation 220 of second port 22, connecting hole 31b is connected with the link 30a driving fit of air inlet pipe 3a.

As Figure 6 and Figure 7, when liquid working fluid 113 flow to its second port 22 along with fluid circuit 2, because the blind end 30b of throttle pipe 3b is that caliber dwindles shape, therefore can form gap 34b (as shown in Figure 7) with second port 22, gap 34b communicates with the blasthole 33b of throttle pipe 3b.Thus, liquid working fluid 113 will be flowed in the runner 32b of throttle pipe 3b by blasthole 33b by gap 34b.After working fluid 113 gasification of heated body 1 inside and being saturation state, portion gas is entered in the compress cell 3 by the inlet end 30 of air inlet pipe 3a, can stress on liquid working fluid 113 liquid levels in the runner 32b, reach identical purpose with above-mentioned first embodiment.

In sum, the utility model is real to be rare novel creation product, it can reach the application target of expection really, solve the defective that exists in the prior art, tool novelty and creativeness meet the application important document of utility model patent fully, file an application according to Patent Law, would like to ask detailed survey and authorize this case patent, to ensure designer's right.

The above is embodiment of the present utility model only, is not so promptly limits claim of the present utility model, and the equivalent structure that every utilization the utility model specification and accompanying drawing content are done changes, and all in like manner is included in the claim of the present utility model.
