The 3rd connecting line 145 on second connecting line 143, so the liquid refrigerant of gentle high pressure is prevented in described
Only the heat in engine room is transferred directly the gas refrigerant to the low temperature and low pressure and prevents the gas refrigeration
The temperature rise of agent.
Therefore, the evil of the air-conditioning cooling performance as caused by raising the gas refrigerant temperature can be prevented in advance
Change.
In addition, the liquid refrigerant of gentle high pressure passes through section below of the configuration in the heat radiation part 110 in described
First connecting line 141 under the 3rd connecting line 145.Therefore, when the gas with the low temperature and low pressure
During refrigerant heat-shift, prevent from being over cooled by the LPG fuel of first connecting line 141 and by described in
LPG fuel is cooled to gratifying temperature.
As described above, the LPG fuel for being cooled to the gratifying temperature passes through the quilt of first outlet 131
There is provided to the steel cylinder 5.
Therefore, the heat exchanger 100 be applied to cause by the high temperature LPG fuel that the engine 3 returns with it is described low
The gas refrigerant of gentle low pressure and it is described in gentle high pressure liquid refrigerant heat-shift, in order to by the LPG fuel
It is cooled to the gratifying temperature.Thereafter, the heat exchanger 100 provides the LPG fuel to the steel cylinder 5.Cause
This, prevents the internal pressure increase in the steel cylinder 5 as caused by flowing into the high temperature LPG fuel.
Meanwhile be included in by the 3rd connecting line 145 it is described in gentle high pressure liquid refrigerant in institute
State uncooled gas refrigerant and pass through the heat with passing through the low temperature of second connecting line 143 and the gas refrigerant of low pressure
Amount exchange is condensed.Accordingly it is possible to prevent the degradation in efficiency of the air-conditioning as caused by the uncooled gas refrigerant is simultaneously
And the expansion efficiency of the expansion valve 30 can be improved.
Therefore, it is applied to according to the heat exchanger 100 for LPI vehicle of the exemplary of the present invention
Reduced by the refrigerant Jing Guo the Air-conditioning Cycle and the heat exchange being back between the LPG fuel of the steel cylinder 5
After the temperature of the LPG fuel, the LPG fuel is flowed into the steel cylinder 5.Accordingly it is possible to prevent in the steel cylinder 5
Internal pressure increase.
In addition, because prevent the internal pressure in the steel cylinder 5 increase, it is possible to swimmingly progress fuel supply and can
To improve merchantability.
In addition, according to the present invention an exemplary the heat exchanger 100 for LPI vehicle be applied into
