The utility model comprises a radiator, a fan and a fan housing, wherein the fan housing is connected with the radiator and the fan is arranged between the radiator and the fan housing. The utility model is characterized in that the fan is connected with a DC motor; a temperature inductor is arranged in a water inlet pipe of the radiator; the DC motor and the temperature inductor which are connected with an earth wire are both connected with a control circuit. Compared with the prior art, the automatic cooler of a backpack combine harvester has the characteristics of less power consumption, high efficiency, etc. Besides, the utility model can avoid the generation of the phenomenon of overheated engines and the phenomenon of cooling plethora.
Description
Technical field
The utility model relates to a kind of vehicle power cooling unit, especially a kind of backpack combine-harvester auto-cool system.
Background technique
Backpack combine-harvester of the prior art is to be improved to install additional by the transportation locomotive to form, utilized traditional cooling fan that motor is cooled off, its cooling capacity is to design with the working condition a certain commonly used that locomotive transports, the specific (special) requirements of high temperature, low speed and high load operation when obviously not meeting harvester operation, in actual job, be prone to the engine overheat phenomenon, both influence operating efficiency, also strengthened the loss of machine.If only solve the engine overheat phenomenon with the method that installs auxiliary water tank, increasing intake grill additional, then be difficult to satisfy the cooling requirement under the various working staties, excess coolant often appears.
In addition, conventional fan is still passed through belt drives by motor, so the motor of cooling fan is housed must be fixed on the vehicle frame of locomotive with elastic support respectively with the radiator that fan housing is housed, be in operation owing to vibration causes that fan and fan housing collide for fear of locomotive, the design value of the radial clearance of blast fan and fan housing is greater than 20mm, and this just greatly reduces the volumetric efficiency of cooling fan; Inevitable loss of traction also makes the mechanical efficiency of fan lower in the belt transmission.In addition, fan still adopts the impeller of sheet metal punching press, and its hydraulic efficiency is just lower.The total efficiency of fan depends on the product of volumetric efficiency, mechanical efficiency and hydraulic efficiency, so the total efficiency of clutch type cooling fan has only 30-40%.
Because the power consumption N f of fan can calculate with following formula: Nf=PVa/D (in the formula: P-fan pressure, Va-fan discharge capacity, D-fan total efficiency), and be subjected to the restriction of driving mode, radiator must be arranged in the dead ahead of motor, and the cooling air flabellum must be installed in the small space between radiator and the motor, this must increase the circulating resistance of cooling air, has promptly increased fan pressure P; Because the total efficiency D of fan is lower, thereby the power Nf that fan consumes increases a lot.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of backpack combine-harvester auto-cool system at above-mentioned deficiency of the prior art, and this auto-cool system has that power consumption is few, efficient is high, can avoid characteristics such as engine overheat phenomenon generation.
The technological scheme that its technical problem that solves the utility model adopts is: backpack combine-harvester auto-cool system, its structure comprises radiator, fan and fan housing, fan housing and radiator join, fan is arranged between radiator and the fan housing, wherein, fan and direct current motor join, and are provided with temperature inductor in the radiator inleting pipe, and the direct current motor and the temperature inductor that join with ground wire all join with control circuit.
Described control circuit comprises power switch K, relay coil J, relay switch JK and resistance R, temperature inductor serial connection relay coil J, resistance R, power switch K and positive source join, relay switch JK is serially connected between direct current motor and the positive source, and power cathode and ground wire join.
This auto-cool system is the unlatching of regulating fan with temperature inductor within the specific limits automatically, to reach the purpose of cooling, minimizing fan power consumption and increase mechanical effect.
Backpack combine-harvester auto-cool system of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) avoided the generation of engine overheat phenomenon and excess coolant phenomenon
The automatic control cooling fan is driving with the motor, not influenced by the rotating speed of motor, when locomotive need dispel the heat, and inductor demand working power supply, cooling fan makes water temperature reduce rapidly with high rotational speed; When temperature was reduced to the minimum temperature of setting, inductor was cut off the electricity supply, and cooling fan quits work, and so just the engine cooling water water temperature was controlled at optimum temperature, had stopped the generation of engine overheat phenomenon or excess coolant phenomenon;
(2) efficient height
The automatic control cooling fan can not be subjected to the influence of the whole assembling of locomotive, can free fan housing, radiator be installed together, guarantee concentric circle strict between fan and the fan housing, reduced the radial clearance of blast fan and fan housing to greatest extent, the volumetric efficiency of fan is greatly improved; On technology, be not subjected to the restriction in space, can utilize the streamline moulding and adopt new material to make fan and impeller, improve the hydraulic efficiency of fan: the mechanical efficiency of motor direct drive mode is also much higher than belt transmission, promptly is greatly improved by the fan total efficiency of the product decision of volumetric efficiency, mechanical efficiency and the hydraulic efficiency of fan;
(3) power consumption is few
The free assembling characteristics of automatic control cooling fan makes selects the optimal ventilation position to become very easy, like this, has reduced the negotiability of cooling air, has reduced fan pressure; The electric energy of storage battery is converted into the power loss that the mechanical energy of cooling fan produces than the engine-driving fan and is much smaller; Owing to can accurately control temperature, reduce the power consumption of fan.By using reaper 15hm to testing
2The influence of other factors to current test got rid of in wheat harvesting result's calculating, draws every mu of test result of saving 0.65L fuel of reaper that average specific is not installed automatic cooling fan.
Description of drawings
Accompanying drawing 1 is the structural representation of backpack combine-harvester auto-cool system.
Embodiment
Explain below with reference to Figure of description backpack combine-harvester auto-cool system of the present utility model being done.
As shown in drawings, backpack combine-harvester auto-cool system of the present utility model, constitute by radiator 1, fan 2, fan housing 3, direct current motor 4, temperature inductor 5 and control circuit, fan housing 3 joins with radiator 1, and the fan 2 that direct current motor 4 joins is arranged between radiator 1 and the fan housing 3, be provided with temperature inductor 5 in the intake pipe of radiator 1, the direct current motor 4 and the temperature inductor 5 that join with ground wire all join with control circuit.
Described control circuit comprises power switch K, relay coil J, relay switch JK and resistance R, temperature inductor 5 serial connection relay coil J, resistance R, power switch K and positive source join, relay switch JK is serially connected between direct current motor 4 and the positive source, and power cathode and ground wire join.Relay switch JK is a normal open switch.
Working principle: when engine water temperature was raised to 100 ℃, temperature inductor was connected and is made the relay coil energising, and the relay switch closure is connected power supply and direct current motor, fan begins to rotate, when temperature dropped to 95 ℃, temperature inductor cut off electric current, and fan stops operating.So repeatedly, temperature is controlled between 95-100 ℃ that helps engine operation most, reaches the purpose that reduces wasted work.
