HEAT EXCHANGER FOR INTERNAL COMBUSTION ENGINES

The present invention relates to a heat exchanger for internal combustion engines where a first fluid, preferably a hot gas, gives off its heat to a second fluid, preferably a coolant liquid. The present invention has caps that limit the heat exchange capacity of the exchanger without causing differential expansions between elements or parts of these elements that may damage the device or reduce its service life due to thermal fatigue. A device thus configured according to the invention can be sized for the engine having a higher rated power, and the same heat exchanger, can be adapted for operating with engines having a lower rated power without the velocity of the gas to be cooled being reduced, thereby preventing the accumulation of particles therein or fouling. 本申请涉及用于内燃机的热交换器，其中，第流体(优选为热气体)将其热放出至第二流体(优选为冷却剂液体)。本发明具有盖罩，该盖罩限制所述交换器的热交换能力而不在元件或这些元件的部件之间引起胀差，由于热疲劳所述胀差可损坏设备或降低其使用寿命。因此，根据本发明配置的设备能够设定尺寸用于具有更高额定功率的发动机，并且相同的热交换器能够适用于与具有较低额定功率的发动机操作而不降低待冷却气体的速度，从而阻止在其中的颗粒或污垢的累积。
