Description

(54) УСТРОЙСТВО ДЛЯ ПРЕДОТВРАЩЕНИЯ ПЕРЕЖОГА СТЕНОК ВЫСОКОТЕМПЕРАТУРНОГО АГРЕГАТА(54) DEVICE FOR PREVENTION OF FIRING WALLS OF A HIGH-TEMPERATURE UNIT

Известны устройства дл  предотвращени  пережога стенок высокотемпературного агрегата, содержащие корпус с соосно установленной внутри высокотемпературной камерой .Devices are known for preventing the walls of a high-temperature unit from breaking through, comprising a housing with a high-temperature chamber coaxially mounted inside.

Однако в известных устройствах низок коэффициент теплопередачи от гор чей стенки к охлаждающему агенту.However, in known devices, the heat transfer coefficient from the hot wall to the cooling agent is low.

Цель изобретени  - интенсификаци  теплообмена .The purpose of the invention is to intensify heat transfer.

Эта цель достигаетс  тем, что в кольцевом зазоре между корпусом и камерой размещены эжекторы, установленные один от другого на рассто нии, равном 1,0-1,5 щирины кольцевого зазора, проходное сечение которого превыщает площадь сопла эжектора в 10-15 раз, а каждый эжектор имеет калибровочное отверстие.This goal is achieved by the fact that in the annular gap between the housing and the chamber there are ejectors placed one after another at a distance of 1.0-1.5 times the width of the annular gap, the flow area of which exceeds the ejector nozzle area by 10-15 times Each ejector has a calibration hole.

На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.

В корпусе 1 устройства установлена высокотемпературна  камера 2. В кольцевом зазоре а между корпусом 1 и камерой 2 размещены эжекторы 3, установленные один от другого на рассто нии, равном 1,0-1,5 щирины кольцевого зазора, проходное сечение которого превыщает площадь соплаA high-temperature chamber 2 is installed in the housing 1 of the device. In the annular gap a, between the housing 1 and the chamber 2, ejectors 3 are placed, installed one from another at a distance of 1.0-1.5 times the width of the annular gap, the flow area of which exceeds the nozzle area

эжектора в 10-15 раз, вследствие чего достигаетс  максимальное охлаждение внутренней стенки камеры 2. Эжекторы 3 имеют калибровочные отверсти  б.ejector 10-15 times, which results in maximum cooling of the inner wall of chamber 2. Ejectors 3 have calibration holes. b.

Через кольцевой зазор о поступает охлаждающий агент, проходит через эжекторы, где разрущаетс  лиминарный подслой у стенки вследствие изменени  направлени  и скорости общего потока хладагента. Наксимальное охлаждение происходит при рассто нии между эжекторами, равном 1,0-1,5 ширины, кольцевого зазора, проходное сечение которого превыщает площадь сопла эжектора в 10-15 раз.A cooling agent flows through the annular gap, passes through ejectors, where the lymph sublayer is destroyed near the wall due to a change in the direction and speed of the total refrigerant flow. The maximum cooling occurs when the distance between the ejectors is 1.0-1.5 width, the annular gap, the flow area of which exceeds the area of the ejector nozzle by 10-15 times.
