Abstract
The utility model discloses a sealing arrangement in the technical field of heat pipe exchanger fitting for integral heat pipe exchanger, comprising a heat pipe. A sealing bolt is arranged on the same axis with the heat pipe in the middle of the heat pipe. A radial convex is positioned at the root of the sealing bolt. The upper part of the heat pipe passes through an upper tube plate arranged in a condensation cavity. The middle part of the heat pipe passes through a median septum installed between the condensation cavity and an evaporating cavity. The lower part of the heat pipe passes through a lower tube plate arranged in the evaporating cavity. The median septum is provided with a step shaped hole and the major diameter section of the step shaped hole is matched with the radial convex. The sealing bolt passes through the minor diameter section of the step shaped hole. A flexible graphite pad is positioned in the annular space formed by the step shaped hole, the radial convex and the sealing bolt. A locking nut for locking the sealing bolt and the median septum is arranged on the sealing bolt. The utility model can make both ends of the heat pipe freely extend as being heated, and the utility model is well sealing, safe and reliable and can be easily dismantled and assembled.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of seal arrangement of integrated thermal heat exchanger.
Background technique
In the prior art, a kind of integrated thermal heat exchanger is arranged, its heat pipe one end is arranged in the condensation cavity, the other end is arranged in the evaporating cavity, for preventing to gang up between condensation cavity and the evaporating cavity, need between condensation cavity and evaporating cavity, seal arrangement be set, at present, a kind of seal arrangement that is applicable to this integrated thermal heat exchanger is arranged, comprise heat pipe, the middle part of heat pipe is provided with the sealing bolt with the coaxial setting of heat pipe, the root of sealing bolt is provided with a radial protrusion, heat pipe top is passed in the upper perforated plate that is provided with in the condensation cavity, the middle part of heat pipe is passed in the central diaphragm that is provided with between condensation cavity and the evaporating cavity, and on the lower perforated plate of lower end conflict in being arranged at evaporating cavity of heat pipe, described central diaphragm is provided with the through hole that matches with described radial protrusion, be threaded on the sealing bolt one with the suitable sealing nut of described through hole, central diaphragm, sealing bolt, be provided with the Expanded graphite packing ring in the annular space that forms between sealing nut and the radial protrusion; This Expanded graphite packing ring can be extruded distortion and compress mutually with through-hole wall on sealing bolt and the central diaphragm, and sealing nut is used to push the Expanded graphite packing ring; There is following shortcoming in the seal arrangement of this structure, and sealing nut need be screwed in the through hole, and its inconvenient operation is difficult for tightening, and the Expanded graphite packing ring is difficult for being extruded tightly, causes poor sealing easily; When being heated, heat pipe can only extend upward, and the Expanded graphite packing ring stretches out outside the central diaphragm easily, makes it and can not seal.
The model utility content
The purpose of this utility model provides a kind of seal arrangement that is applicable to the integrated thermal heat exchanger, and the heat pipe two ends can freely be stretched, and good seal is safe and reliable, is easy to dismounting.
The purpose of this utility model is achieved in that a kind of seal arrangement that is applicable to the integrated thermal heat exchanger, comprise heat pipe, the middle part of heat pipe is provided with the sealing bolt with the coaxial setting of heat pipe, the root of sealing bolt is provided with a radial protrusion, heat pipe top is passed in the upper perforated plate that is provided with in the condensation cavity, the middle part of heat pipe is passed in the central diaphragm that is provided with between condensation cavity and the evaporating cavity, the lower perforated plate that is arranged in the evaporating cavity is passed in the lower end of heat pipe, described central diaphragm is provided with a stepped bore, the big footpath section and the described radial protrusion of this stepped bore are suitable, sealing bolt passes the path section of this stepped bore, stepped bore, be provided with the Expanded graphite packing ring in the annular space that forms between radial protrusion and the sealing bolt, sealing bolt is provided with the locking nut that sealing bolt and central diaphragm are locked mutually.
The utility model utilizes locking nut and sealing bolt that heat pipe is fixed on the central diaphragm, and the two ends up and down of heat pipe can freely be stretched, and is unlikely to because of the extruding Expanded graphite packing ring that expands causes poor sealing, and therefore, its use is more reliable; Because locking nut exposes outside the central diaphragm, its easy accessibility is easy to push tight Expanded graphite packing ring; As seen, the utility model good seal, safe and reliable, be easy to dismounting.
