As preferably, said heat pipe assembly comprises heat pipe, sealing ring and fin, and said heat pipe is axially placed along outlet pipe; One end passes the outlet pipe inner casing, gets in the interior pipe of outlet pipe, and the other end is in cooling water chamber; A plurality of heat pipe assemblies are arranged side by side, and said sealing ring is enclosed within on the said heat pipe, and the internal diameter of sealing ring closely contacts with the tube wall of heat pipe; The external diameter of sealing ring and outlet pipe inner casing fit tightly; Guarantee the excellent sealing at heat pipe jack place, fin axially axially is 90 ° of placements with heat pipe along heat pipe, and a plurality of fins are arranged in the heat pipe surface side by side and are in contact with it well.
Beneficial effect:
1. be employed in and arrange on the outlet pipe that heat pipe and cooling water chamber reduce the strategy of delivery temperature; During work; The anti-explosion diesel engine exhaust is flowed in outlet pipe, managing, and exhaust institute heat content passes to the cooling water in the cooling water chamber through the heat pipe assembly, and cooling water intake links to each other with the anti-explosion diesel engine cooling water pipeline with coolant outlet; And constitute the lasting coolant exhaust of circulation, greatly reduce delivery temperature.
2. heat pipe for thermal conductivity is functional, and following heat that can transmit of unit heat transfer area is the several times of traditional sense heat conducting element, adopts heat pipe as heat transfer element in the anti-explosion diesel engine outlet pipe, can rapidly, effectively reduce delivery temperature; The isothermal of heat pipe is functional, and functional reliability and stronger to the adaptive capacity of environment is adapted at applying on the anti-explosion diesel engine.
3. this anti-explosion diesel engine exhaust pipe structure is compact, only on common anti-explosion diesel engine outlet pipe basis, has increased one deck housing, and diameter increases slightly, and structure is simple relatively, convenient layout on anti-explosion diesel engine.
Description of drawings
In conjunction with accompanying drawing, other characteristics of the present invention and advantage can become clearer from the explanation of following preferred implementation of coming by way of example principle of the present invention is made an explanation.
Fig. 1 is the apparatus structure schematic representation of a kind of mode of execution of anti-explosion diesel engine outlet pipe of the present invention;
Fig. 2 is heat pipe assembly structural representation in a kind of mode of execution of anti-explosion diesel engine outlet pipe of the present invention;
Among the figure: 1-cooling water intake, 2-outlet pipe shell, 3-heat pipe assembly, 4-coolant outlet, 5-outlet pipe inner casing, 31-heat pipe, 32-sealing ring, 33-fin.
Embodiment
To combine accompanying drawing that mode of execution of the present invention is described in detail below:
As shown in Figure 1, present embodiment comprises cooling water intake 1, outlet pipe shell 2, heat pipe assembly 3, coolant outlet 4, outlet pipe inner casing 5.Form pipe in the outlet pipe in the said outlet pipe inner casing, form airtight cooling water chamber between said outlet pipe inner casing and the outlet pipe shell, cooling water intake 1 links to each other with the anti-explosion diesel engine cooling water pipeline with coolant outlet 4; Cooling water gets into cooling water chamber through cooling water intake 1; And flow out from coolant outlet 4, said heat pipe assembly 3 is axially placed along outlet pipe, and an end passes outlet pipe inner casing 5; Get in the interior pipe of outlet pipe; The other end is in cooling water chamber, and a plurality of heat pipe assemblies are arranged side by side, and tries one's best into even distribution.
As shown in Figure 2, heat pipe assembly 3 comprises heat pipe 31, sealing ring 32 and fin 33.Heat pipe 31 is axially placed along outlet pipe, and an end passes outlet pipe inner casing 5, gets in the outlet pipe in the pipe; The other end is in cooling water chamber; A plurality of heat pipe assemblies are arranged side by side, and said sealing ring 32 is enclosed within on the said heat pipe 31, and the internal diameter of sealing ring 32 closely contacts with the tube wall of heat pipe; The external diameter of sealing ring 32 and outlet pipe inner casing 5 fit tightly; Guarantee the excellent sealing at heat pipe jack place, fin 33 axially axially is 90 ° of placements with heat pipe along heat pipe, and a plurality of fins are arranged in the heat pipe surface side by side and are in contact with it well.
Working principle:
Anti-explosion diesel engine flows during high-temperature exhaust air is managed in outlet pipe in the course of the work, and exhaust institute heat content is delivered to inside heat pipe through the fin in the pipe in the insertion outlet pipe and the outer wall of heat pipe, is delivered to the surface of inserting the heat pipe in the cooling water chamber then.The cooling water that temperature is lower flows out from cooling water intake inflow cooling water chamber and from coolant outlet; When cooling water flows through the fin that is arranged in cooling water chamber and heat pipe outer wall; Taken away a large amount of heats, reduced heat pipe temperature, cooling water intake links to each other with the cooling water pipeline of anti-explosion diesel engine respectively with coolant outlet; Cooling water circulates in cooling water chamber and peripheral cooling system, and the heat that cooling water absorbs constantly is dispersed in the environment.In this way, exhaust gas heat distributes continuously, and its temperature is minimized.In outlet pipe, manage when flowing when exhaust, be disposed in that a plurality of heat pipe assemblies in the pipe and cooling water chamber constantly cool off in the outlet pipe, delivery temperature is reduced to below the desired temperature the most at last.
Material therefor and technology are all in accordance with national explosion-proof criteria among the present invention.
Though described mode of execution of the present invention in conjunction with accompanying drawing, those of ordinary skills can make various distortion or modification within the scope of the appended claims.
