Description

Изобретение относитс к системам охлаждени тепловых цвигагелей.,The invention relates to cooling systems for thermal dvigagels.

Известна система испарительного охлазкдени теплового двигател , содержаща теплообменник с испарительной камерой , снабженной отвод5шщм патрубком, выходной участок которого размехцен в выхлопном тракте двигател fll .A heat engine evaporative cooling system is known, comprising a heat exchanger with an evaporation chamber equipped with a branch pipe, the outlet section of which is in the exhaust path of the engine fll.

Основным недостатком известной системы охлаждени вл етс невозможность обеспечени регулировани интенсивности испарени охлаждающей жидкости в испарительной камере в результате чего снижаетс эффективность и надежность охлаждени теплового двигател при увеличении температуры выше расчетной.The main disadvantage of the known cooling system is the inability to control the intensity of evaporation of the coolant in the evaporation chamber, which reduces the efficiency and reliability of cooling the heat engine when the temperature rises above the calculated one.

Цель изобретени - повышение надежности путем обеспечени регулированного охлаждени .The purpose of the invention is to increase reliability by providing controlled cooling.

Указанна цель достигаетс тем, что выходной участок снабжен размещенным на его периферии биметаллическим силь фоном, плотно соединен1 ым одним своимThis goal is achieved by the fact that the exit section is provided with a bimetallic force placed on its periphery, tightly connected by its own

торцом с патрубком, а другим - с тор- нрм дополнительно установленной втулки , расположенной внутри патрубка с возможностью продольного перемещени .the end with the pipe, and the other with the torque of the additionally installed sleeve, located inside the pipe with the possibility of longitudinal movement.

На чертеже представлена система испарительного охлаждени теплового двигател , общий вид.The drawing shows the evaporative cooling system of a heat engine, a general view.

Система испарительного охлаждени теплового двигател срдержит теплооб1менник 1 с испарительной ;камерой 2, The evaporative cooling system of the heat engine will hold the heat sink 1 with the evaporative chamber 2,

10 заполненной охлаждающей жидкостью 3 и снабженной отвод щим патрубком 4, выходной участок 5 которого размещен в выхлопном тракте 6 двигател . Выходной участок 5 патрубка 4 снабжен раэ1IS мещенным на его периферии биметаллическим сильфоном 7, Сильфон 7 плотно соединен своим торцом 8 с патрубком 4, а другим торцом 9 - с торцом 1О втулки 11, расположенной внутри патрубка 4 10 filled with coolant 3 and equipped with a discharge pipe 4, the outlet section 5 of which is located in the exhaust path 6 of the engine. The output section 5 of the nozzle 4 is provided with a bimetallic bellows 7 placed at its periphery, the bellows 7 is tightly connected with its end 8 to the pipe 4, and the other end 9 to the end 1O of the sleeve 11 located inside the pipe 4

Claims

20 with the possibility of longitudinal movement. A heat insulating sleeve 1 placed inside the bellows 7 is installed on the periphery of the output section 5.

2. The exhaust 5 / track 6 contains a nozzle nozzle 13. The longitudinal movement of the sleeve 11 during operation is carried out in the nozzle I nozzle 13 coaxially with the latter. When heat is supplied from the coolant heat exchanger, the latter is evaporated, and its vapor through the exhaust pipe 4 is removed from the evaporation chamber 2 due to ejection by exhaust gases. The increase in the temperature of the exhaust gases and, consequently, the temperature of the cooled surfaces of the engine causes an increase in the linear dimensions of the bimetallic bellows 7. In this way 11, attached to the bellows 7, moves along the axis of the nozzle nozzle 13 in the direction of its critical section. When the 10 end 11 of the critical section reaches the nozzle 13, which corresponds to the maximum temperature of the exhaust gases, the maximum vacuum in the pipe 4 and the evaporation chamber 2 is achieved, which provides an increase in the intensity-evaporation of the cooling fluid 3 and, consequently, an increase in heat removal . Equipping the outlet section of the outlet nozzle with a bimetallic bellows placed at its periphery, tightly connected with one nozzle to the nozzle and the other with the additionally installed sleeve located inside the nozzle with the possibility of longitudinal movement, automatically adjusts the evaporation of the coolant in the evaporation chamber and to improve the efficiency and reliability of engine cooling, the claims of the invention. The evaporative cooling system of the heat engine, containing conductive heat exchanger with the evaporator chamber provided with a conductive nozzle outlet, the outlet portion of which is placed in the exhaust tract of the engine, characterized in that, in order povpieni. reliability by providing controlled cooling, the output section is provided with a bimetallic bellows placed on its periphery, tightly connected by one end to the branch pipe, and the other to the end of the additionally installed sleeve located inside the branch pipe with the possibility of longitudinal movement.
