Abstract
The utility model relates to the technical field of automobile construction and engine cooling systems and relates to a heat exchanger for auxiliary cooling of a fire fighting truck. The heat exchanger is composed of a heat exchanger housing and heat exchange tubes which are uniformly distributed in the heat exchanger housing and fixed on the heat exchanger housing via front and rear water chambers at two ends and baffle plates in the middle. A fire pump cooling water inlet and a fire pump cooling water outlet are formed in the rear water chamber. The front and rear water chambers are communicated with the heat exchange tubes. The front and rear portions of the heat exchanger are provided with a cooling liquid inlet and a cooling liquid outlet. The baffle plates divide a cooling liquid cavity formed by the inner wall of the heat exchanger housing and outer walls of the heat exchange tubes. Partition plates are arranged in the front water chamber and the rear water chamber. The heat exchanger for auxiliary cooling of the fire fighting truck is high in heat exchange capability, small in size and little in resistance and is suitable for an original truck cooling system and an auxiliary heat exchanger assembly required by the fire fighting truck and also capable of resolving a cooling problem arising from continuous operation of the fire fighting truck.
Description
Technical field
It is auxiliary cooling with heat exchanger that the utility model relates to a kind of fire-fighting truck, belongs to the technical field of automobile construction and engine-cooling system.
Background technique
FAW Jiefang Automotive Company, Ltd.'s fire-fighting truck newly developed required in arbitrary season of national any area, and fire-fighting truck can be not less than 6 hours the time of fighting one battle after another.
According to test result, the cooling system of former car is worked and is had larger hot air reflux under parking operating mode, and cooling system heat dissipation potential declines, and can not meet the demands.Affected by arrangement, improve radiator front and accumulate in difficulty; Add barge board temperature in engine compartment when causing the higher speed of a motor vehicle and raise, reduce the working life of rubber parts.Common supplementary heat exchanger cannot directly apply to fire-fighting truck.We are by performance Analysis and Calculation, brand-new design the auxiliary cooling heat exchanger of using of a kind of fire-fighting truck.
Summary of the invention
Technical problem to be solved in the utility model is to have overcome the problem that prior art exists, and provides a kind of fire-fighting truck auxiliary cooling with heat exchanger, the cooling requirement of motor while meeting fire-fighting vehicle long time continuous working.
For solving the problems of the technologies described above, the utility model is to adopt following technological scheme to realize, and accompanying drawings is as follows:
Fire-fighting truck is auxiliary cooling to be comprised of heat exchanger shell and heat exchanging tube with a heat exchanger, it is characterized in that:
Described heat exchanging tube 1 is distributed in heat exchanger shell 2, and be fixed on heat exchanger shell 2 by front water chamber 6, rear hydroecium 5 and the middle deflection plate 3 at two ends, rear hydroecium 5 is provided with fire water pump cooling water intake 9, fire water pump cooling water outlet 10, forward and backward hydroecium and heat exchanging tube 1 UNICOM, described heat exchanger shell 2 front and rear portions are provided with cooling liquid inlet 7, cooling liquid outlet 8.
Deflection plate described in technological scheme 3 is separated the cooling liquid cavity of heat exchanger shell 2 inwalls and heat exchanging tube 1 outer wall formation, by reducing the circulation area of cooling liquid, improves flow velocity, and the surperficial convection transfer rate of heat exchanging tube 1 outer wall increases.
For the vehicle that adopts different motors, deflection plate described in technological scheme 3, according to the requirement of system flow resistance, selecting deflection plate quantity is 3 or 5, regulate the position of deflection plate, by reducing the circulation area of cooling liquid, improve flow velocity, the surperficial convection transfer rate of heat exchanging tube 1 outer wall increases.
In front water chamber described in technological scheme 6 and rear hydroecium 5, be provided with dividing plate.
Compared with prior art the beneficial effects of the utility model are:
The utlity model has feature simple in structure, can be directly used in the auxiliary cooling of fire-fighting truck; The utility model exchange capability of heat is high, volume is little, resistance is little, be applicable to the supplementary heat exchanger assembly of former car cooling system and fire-fighting truck requirement, has solved the cooling problem that fire-fighting truck fights one battle after another.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
In figure: 1, heat exchanging tube; 2, heat exchanger shell; 3, deflection plate; 4, sealing cover; 5, rear hydroecium; 6, front water chamber; 7, cooling liquid inlet; 8, cooling liquid outlet; 9, fire water pump cooling water intake; 10, fire water pump cooling water outlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail:
This heat exchanger is to consist of the following components:
1, heat exchanging tube; 2, heat exchanger shell; 3, deflection plate; 4, sealing cover;
5, rear hydroecium (interior band dividing plate); 6, front water chamber (interior band dividing plate); 7, cooling liquid inlet;
8, cooling liquid outlet; 9, fire water pump cooling water intake; 10, fire water pump cooling water outlet.
When fire-fighting truck is worked, it is auxiliary cooling with heat exchanger that the cooling liquid flowing out from vehicle radiator flows into fire-fighting truck from cooling liquid inlet 7, with heat exchanging tube 1 outer surface generation convection heat exchange, deflection plate 3 can improve cooling liquid speed, deflection plate 3 is separated the cooling liquid cavity of heat exchanger shell 2 inwalls and heat exchanging tube 1 outer wall formation, by reducing the circulation area of cooling liquid, improve flow velocity, the surperficial convection transfer rate of heat exchanging tube 1 outer wall increases.
For the vehicle that adopts different motors, position and the quantity of deflection plate 3 are adjustable, according to flow resistance, calculate, and it is the best that the quantity of deflection plate 3 is three or five, by reducing the circulation area of cooling liquid, improve flow velocity, the surperficial convection transfer rate of heat exchanging tube 1 outer wall increases.
After reducing, coolant temperature flows out from cooling liquid outlet 8, the cooling water of fire water pump flows into heat exchanging tube 1 from fire water pump cooling water intake 9 simultaneously, with heat exchanging tube 1 internal surface generation convection heat exchange, the effect that front water chamber 6 and rear hydroecium 5 play sealing and improve cooling water flow velocity, after raising, cooling water temperature flows out from fire water pump cooling water outlet 10, finally reach new thermal equilibrium, thereby reached the object of auxiliary cooling vehicle motor, meet the requirement of fire-fighting vehicle long time continuous working.Different vehicles is arranged to cooling liquid inlet 7 and cooling liquid outlet 8 can exchange, and versatility is good.
