Pass through the design of above-mentioned preferable angle so that the vibration of free end reaches optimal, so that the efficiency of heating surface reaches To optimal.

As shown in figure 9, the tube bank of floating coiled pipe is 4, tube bank A, B, C, D UNICOMs.Certainly, four are not limited to, can be with It is arranged as required to multiple, specific attachment structure is identical with Fig. 4.

The floating coiled pipe 22 is multiple, and multiple floating coiled pipes 22 independently connect the first bobbin carriage 2 and the second bobbin carriage 8, I.e. multiple floating coiled pipes 22 are parallel-connection structure.

The fuel oil preheating of automobile of the present utility model, especially electric bus, heat-exchange system, when the igniting of heater 15 adds After heat, when water temperature≤80 DEG C, electric calorifie installation 9 works automatically, and when water temperature >=95 DEG C, electric calorifie installation 9 is stopped, water pump 14 by the heat-exchanger rig 21 of water suction heater 15, and after recirculated water is heated, water is passed through into recirculated water by the effect of water pump 14 Road 17 drains back to main body water circulation system, i.e. water tank 16, and the shut-off of recirculated water is controlled by water valve 13；

Passenger cabin is recycling next hot water by heater 15, and hot water is sucked into passenger cabin heating system by water pump 2 In radiator, the temperature in member storehouse is improved to room temperature in whole cyclic process, and in member storehouse temperature by controlling The intelligent decision of device 10, when temperature≤10 DEG C, it is judged as winter, controller controls the unlatching of water pump, sentenced when temperature >=25 DEG C Break and closed for summer, controller control water pump 2；

Battery compartment is recycling next hot water by heater 15, and hot water is sucked into battery compartment heating system by water pump 5 In radiator, when battery compartment temperature sensor temperature sensor be≤5 DEG C when, controller control water pump 5 work, when temperature >=10 DEG C, controller control water pump 5 is stopped；When to battery compartment heat supply, valve 4 is opened, and valve 20 is closed；

When controller 10 is judged as summer, valve 4 is closed, opens valve 20, the partial circulating of cooling water tank 6 dissipates with battery compartment Hot systems 7 form side by side, and then the temperature in intelligent control battery storehouse keeps constant temperature.In main body water circulation system 16, battery compartment It is equipped with cooling-water temperature sensor 12 on cooling system 7 to be connected with the data of controller 10 with storehouse temperature sensor 8, controller carries out intelligence and sentenced Break to control the operation of above-mentioned function, real time temperature is all shown on instrument board 11, enabled a driver to more easily The temperature change of various pieces is grasped, and corresponding control is made according to the change of temperature.

Preferably, service on buses or trains storehouse temperature sensor 28 measure temperature also real-time display on instrument board 11.

Preferably, high-pressure hydraulic pump 14 is equipped with butterfly fan connection water inlet pipe and water outlet pipe.

Service on buses or trains storehouse radiator be by 8 groups of hollow groups of fins into.

Battery compartment supply, cooling system equally by heater 15 electric bus traveling during, due to being electrokinetic cell, Consuming electricity is big, and temperature change is fast, passes through main body water circulation system 16 when heater 15 recycles next thermal source, by controller 10 After intelligent decision temperature by high-pressure hydraulic pump 5 suck thermal source, be recycled to by 4 pieces of hollow groups of fins into cooling system 7, separately One end is back to main body water circulation system 16 provided with water-flow circuit.

Although the utility model is disclosed as above with preferred embodiment, the utility model is not limited to this.Any Art personnel, do not departing from spirit and scope of the present utility model, can make various changes or modifications, therefore this practicality New protection domain should be defined by claim limited range.
