Besides, the relay used by the utility model is a temperature sensing relay. The utility model utilizes directly the water temperature of an engine cooling system as control information, and when the temperature of the cooling water exceeds the rated temperature, the blade of a fan rotates to a designed incidence to load the fan; when the temperature of the cooling water is below the rated temperature, the blade of the fan restores to the zero incidence to stop the fan. The fan can perform effectively functions and save energy, and besides, the cooling fan of the utility model has the advantages of small physical deterioration, long service life, high reliability, easy manufacture, etc.
Description
The utility model is relevant with the vehicle motor cooling fan.
The vehicle motor cooling fan of existing variable-vane angle can be divided into mechanical control and two kinds of patterns of automatic guidance by its structural shape.The fan person of being to use of mechanical control is according to the operating mode of driving engine, and the direct control control mechanism changes the fan blade angle, and not only control is complicated, and increases operator's burden.Existing automatic guidance fan, its blade installation angle is that the height with engine speed becomes, so the air quantity that fan is produced also is to become with engine speed, there is no direct relation with cooling water expansion tank water temperature in the cooling system, fan can not play a role effectively according to the variation of temperature of cooling water expansion tank, do a large amount of idle works, waste energy.And this fan is very high to blade material and manufacture process requirement.
Task of the present utility model is to design a kind of engine cooling water water temperature of directly utilizing as control information, the stagger angle of automatic guidance fan blade, thus regulate air quantity of fan, effectively bring into play the cooling fan of its effect.Reach reliable operation, energy savings alleviates the purpose of operator's burden.
Cooling fan of the present utility model as shown in drawings, it is made up of the belt pulley (1) of being with the skirt section, petiole (2), blade (3) etc., petiole is installed on the skirt section of belt pulley by petiole nut (4) and petiole guide (5), petiole nut and petiole guide are equipped with end face ball bearing of main shaft (6) together, thereby petiole can relatively rotate the change blade incidence in the petiole guide.The utility model is the most outstanding to be characterised in that the automatic control device of a changed blade incidence of being made up of temperature-sensitive paraffin thruster (7), transmission ring (8), transmission hook (9) etc., and is installed in the thermal relay in the cooling system.Described temperature-sensitive paraffin thruster structure as shown in Figure 3, it is made up of resistor wire (10), temperature-sensitive paraffin (11), rubber sealing boot (12), push rod (13), shell (14) etc., the resistor wire back of connecting with relay normally open contact joins with power supply.When cooling water expansion tank had reached temperature rating, the closed power supply of connecting the thruster resistor wire of thermal relay normally open contact, resistor wire heating power, temperature-sensitive paraffin expanded by heating, the push rod layman that is squeezed promoted the transmission ring motion.Because transmission shank body is fixed on the transmission ring, it will move with transmission ring, the hook portion of transmission hook contacts with blade in addition, and contact position and blade centreline have an eccentric distance e (as shown in Figure 2), blade just can turn to the design and installation angle by relative petiole guide under the effect of transmission hook, fan pectinid amount increases.When cooling water temperature was lower than temperature rating, the thermal relay normally open contact resetted, and the thruster resistor wire stops heating, temperature-sensitive paraffin cooling shrinkage, and push rod is return.For guaranteeing that blade returns to 0 degree stagger angle.Blade retracing spring (15) has been installed on the petiole guide, and its end is fixed on the belt pulley skirt section, and the other end is fixed on the blade.In addition, having the steady arm (16) that play the guiding role more than two to pass transmission ring is installed on the belt pulley, to guarantee the transmission ring motion accurately and reliably, the stop nut (17) of adjustable transmission ring stroke also is housed, on steady arm with the maximum stagger angle of adjusting vane.For under blade incidence automatic control device or the out of order situation of thermal relay, also can the adjusting vane stagger angle, be with a safety sleeve outside aforementioned steady arm, it can pass through setting nut (19) thereby mobile transmission ring adjusting vane stagger angle (shown in Fig. 1,4,5).Cooling fan of the present utility model is equipped with a dust cover (20) at belt pulley skirt section end face, there is an electric current input media to be installed on this cover plate, this electric current input media comprises collector ring (21), touch block (22), brush (23) etc., and insulating gel plank (24) is equipped with at the two ends of touch block and collector ring.Brush links to each other with extension spring steady arm (26) on being installed in body by extension spring (25), and insulcrete (27) is housed between extension spring steady arm and body.Cooling fan of the present utility model, power supply one utmost point that is used for heating the thruster resistor wire links to each other with body, another utmost point is received the extension spring steady arm and is received an end of the resistor wire in the temperature-sensitive paraffin thruster by electric current input media and lead behind the thermal relay open contact, this resistor wire other end links to each other (as shown in figs. 1 and 6) with body through shell.Another prominent feature of the present utility model is that described thermal relay can be a temperature-sensitive paraffin relay (28), its structure as shown in Figure 7, it is made up of moving contact (29), break back contact (30), moving contact binding post (31), break back contact binding post (32), temperature-sensitive paraffin (33), rubber sealing boot (34), moving contact drive spindle (35), moving contact retracing spring (36), shell (37), wax head metal case (38) and lead, mounting screw etc.Temperature-sensitive melting point of paraffin wax temperature is a little less than the cooling water expansion tank temperature rating.The wax head metal case of temperature-sensitive paraffin relay is installed in the cooling water circulation system, directly contacts with cooling water expansion tank.When cooling water temperature met or exceeded temperature rating, the temperature-sensitive melted paraffin wax also expanded, by the motion of rubber sealing boot extruding moving contact drive spindle, moving contact closure.When coolant water temperature was lower than temperature rating, paraffin was solid shape, and shrank, and moving contact remains on the normally open position under action of reset spring.
Cooling fan of the present utility model is control information with the cooling water temperature, the setting angle of automatic guidance fan blade, and when cooling water temperature meets or exceeds a certain temperature rating (as 92 ℃), blade turns to the design and installation angle automatically, and fan is fully loaded with pectinid.When cooling water temperature was lower than this temperature rating, it was zero position that blade automatically resets to stagger angle, and fan stops pectinid, only consumes minimum power, and fan can play a role effectively, greatly energy savings.It is little that cooling fan of the present utility model also has mechanical wear, long working life, and good reliability, simple in structure, advantage such as easy to manufacture.
