Description

Изобретение относитс  к дигател м внутреннего сгорани .This invention relates to internal combustion engine digesters.

Известны поршни дл  двигател  внутреннего сгорани , содержащие головку по меньшей мере с одной замкнутой полостью, частично заполненной жидким легкокип шим, веществом, и системо каналов дл  циркул ции охлаждающей среды.Pistons for an internal combustion engine are known, comprising a head with at least one closed cavity partially filled with a light boiling liquid, a substance, and a system of channels for circulating a cooling medium.

Недостаток извест1п 1х поршней заключаетс  в сравнительно невысокой интенсивности отвода тепла через замкнутую полость головки за счет взбалтывани  заполн ющей ее среды, что снижает интенсивность отвода тепла через систему циркул ционного охлаждени  в цепом.A disadvantage of the known 1x pistons is the relatively low intensity of heat removal through the closed cavity of the head due to agitation of the filling medium, which reduces the intensity of heat removal through the system of circulation cooling in the chain.

Цепью изобретени   вл етс  повышение эффективности охлаждени  поршн .The chain of the invention is to increase the cooling efficiency of the piston.

Это осуществл етс  введением в замкнутую полость средств, способствующих возрастанию интенсивности теплообмена, и достигаетс  организацией функционировани  замкнутой полости в рехсиме тепловой трубы.This is accomplished by introducing into the closed cavity of means that increase the intensity of heat exchange, and is achieved by organizing the functioning of the closed cavity in the heat pipe retrieval.

Дл  этого внутренние стенки замкнутой полости покрыты твердым капилл росодержащим веществом, обеспечивающим ее функционирование в режиме тепловой трубы.For this, the internal walls of the closed cavity are covered with solid capillary containing substance, which ensures its functioning in the heat pipe mode.

На чертеже схематично изображено предлагаемое устройство. IThe drawing schematically shows the proposed device. I

Поршень двигател  внутреннего сгорани  включает в себ  головку 1 по крайней мере с одной замкнутой полостью 2, частично заполненной жидким, легкокип щим веществом, и систему каналов 3 и 4 дл  циркул ции охлаждающей среды, причем внутренние стенки замкнутых полостей покрыты твердым капилл ро со держащим веществом дл  работы в режиме тепловой трубы.The piston of an internal combustion engine includes a head 1 with at least one closed cavity 2 partially filled with a liquid boiling substance and a system of channels 3 and 4 for circulating a cooling medium, the internal walls of the closed cavities being covered with solid capillary containing substance for heat pipe operation.

Поршень работает следующим образом.The piston works as follows.

Охлаждающа  среда по системе каналов 3 и 4 поступает к замкнутым полост м 2, частично заполненным легкокип щей жидкостью и внутренними стенками, покрытыми твердым капилл росодержащим веществом. За счетThe cooling medium through the system of channels 3 and 4 goes to a closed cavity 2, partially filled with a light boiling liquid and the internal walls covered with a solid capillary containing substance. By

изменени  агрегатного состо ни  теплоносител  при работе полости в режиме тепловой трубы резко возрастает интенсивность отвода тепла от головки 1 поршн , в результате чего повышаетс  интенсивность охлаждени  поршневой группы.changes in the aggregate state of the coolant when the cavity is operating in the heat pipe mode, the intensity of heat removal from the piston head 1 sharply increases, as a result of which the cooling intensity of the piston group increases.
