Abstract

The utility model provides a turbine intercooler of an automotive power system, relating to an automotive cooling device. The turbine intercooler of the automotive power system comprises a shell, wherein a cooling part consisting of fins is arranged at the middle of the shell; cooling pipelines sealed with strip seals are arranged among the fins; and each cooling pipeline has is provided with an inlet and an outlet. The turbine intercooler of the automotive power system is characterized in that transition pipes are arranged between the inlets and the cooling pipelines and as well as between the outlets of and the cooling pipelines; the transition pipes are arranged on two sides of the shell; the transition pipes form a measurement space in a surrounding way; and a measurement hole is formed in the side face of the each transition pipe. The turbine intercooler of the automotive power system has the measurement space of which the volume is larger; a measured gas is buffered in the measurement space, so that the stability of a measurement environment is guaranteed and the measurement accuracy is improved; meanwhile, a temperature transducer, a pressure transducer or other monitoring detectors can be installed on the measurement hole according to demands; and in addition, the repair and the replacement are facilitated.

Description

The turbine intercooler of a kind of power train in vehicle application system

Technical field

The utility model relates to cooler, particularly a kind of turbine intercooler for automotive power.

Background technique

Turbine is the rotary power machinery that a kind of transformation of energy with flow working medium is mechanical work, is one of critical piece of aeroengine, gas turbine and steam turbine.Be low-voltage high-temperature gas from turbine gas out, so need to cool off, corresponding device is called interstage cooler, namely intercooler.

General intercooler is the structure of a heat exchanger, has housing, enclosure interior is provided with the passage that hot gas flows, the intermediate portion of housing is the radiator portion that is made of the fin that a large amount of rules are arranged, it is exactly the hot gas passage that is sealed to form by strip of paper used for sealing between fin and the fin, the import and export of hot gas are set in the both sides of housing, have just consisted of the intercooler of an air cooling heat exchange.

The present equipment such as automobile electronization, intelligent requirements are more and more higher, thus need to monitor the parameter of links, and turbine exhaust is an important combustion parameter, more should in time be monitored.In the prior art, setting realizes data monitoring such as air pressure, temperature transducer at the turbine rear, and this mounting type complex structure, loaded down with trivial details is measured relatively difficulty of variety renovation; Because the gas that turbine is discharged has certain flow, and whole measurement environment is unstable, measurement accuracy is lower simultaneously.

The model utility content

The purpose of this utility model is to invent a kind of turbine intercooler that can detect easily the power train in vehicle application system of turbine gas parameter.

This intercooler comprises housing, it is the cooling segment that fin consists of in the middle of the housing, it is the cooling pipe of strip of paper used for sealing sealing between the fin, cooling pipe has import and outlet, it is characterized in that: be respectively equipped with transition tube between import and export and the cooling pipe, transition tube is arranged on the both sides of housing, and transition tube surrounds a measurement space, in the side of transition tube, be provided with a measuring hole.

The utility model has designed one and has had volume obviously greater than the measurement space of cooling pipe sectional area, the gas that allows turbine discharge cushions in this space, distribution of gas is even, measurement environment is stable, guarantees in this measurement environment the measurement accuracy to gas density, temperature, pressure and other parameters.Simultaneously, as required mounting temperature sensor, pressure transducer or other various monitoring detectors on the measuring hole, maintenance, change convenient.

Because it is higher to detect the seal request of mouth, for the ease of the installation of sensor, so preferred: measuring hole is arranged on the pedestal of a thickening, and described pedestal is provided with seal groove and attachment hole simultaneously.As previously mentioned, the gas that turbine is discharged is low-pressure gas, and the pedestal of thickening can overcome the impact in local exterior's pressure difference of measuring hole position.

Further preferred, the shape of transition tube is: close up to import and export from housing, the lines of outline that consists of its profile is the continuous transition curve.As previously mentioned, the measurement space volume that transition tube surrounds is larger, and inner support is poorer than cooling pipe, and this shape does not have as much as possible corner angle and faces directly, is in order to reduce pressure to the impact of whole transition tube, to guarantee working life equally.

Fig. 2, the sectional view that cooling pipe and fin, strip of paper used for sealing consist of;

Fig. 3, the structural drawing of the pedestal 8 of thickening.

Embodiment

Such as Fig. 1, intercooler of the present utility model adopts the hard good conductors such as stainless steel, aluminium to make, and housing 1 generally is square, and the centre is the cooling segment that fin 2 that rule is arranged consists of.Such as Fig. 2, be the cooling pipe 4 that is surrounded by strip of paper used for sealing 3 sealings between the fin 2.Whole radiating principle is exactly the hot gas that mobile turbine is discharged in the cooling pipe, and then cool air is crossed fin from the case side top blast, realizes heat radiation.Cooling pipe 4 is continuous bendings, and caliber is less, to improve radiating effect.Both sides at housing 1, be connected ground with cooling pipe, be provided with two transition tube 5, import 6 and the outlet 7 of hot gas are set on the transition tube 5 again, the shape of transition tube 5 is that connecting housing parts is roomy, close up gradually toward the curve of import and export with continuous transition, form the profile without corner angle, reducing external pressure affects it.

Space in the transition tube 5 becomes measurement space, because opening is larger, the transition tube volume is also larger, so the hot gas that turbine is discharged at first can fully cushion in measurement space before entering cooling pipe, the parameters such as the pressure of the hot gas in this space, temperature are more stable, and measurement result is accurate.

Such as Fig. 1 and Fig. 3, the side of transition tube 5 is provided with the pedestal 8 of a thickening, and pedestal is provided with measuring hole 9, and this measuring hole 9 can be used for the installation of the sensors such as temperature, pressure.Install in order to improve sealing effect and to be convenient to simultaneously, pedestal 8 is provided with attachment hole 10 and seal groove 11.

To sum up, the utility model provides a structural stability, measurement space that fastness is high, be provided with simultaneously the measuring hole of dismantled and assembled various sensors, the utility model can be applied on the various automobile-used power system of intelligent requirements, and the reliability of survey data and convenience all are much higher than prior art.
