Description

Technical Field

[0001] The invention belongs to the field of radiators, and in particular relates to a radiator for a forest fire fighting vehicle. Background Art

[0002] Air conditioning radiator and radiator are both necessary components of the car's cooling system. Among them, the radiator generally includes a water inlet chamber, a water outlet chamber, a radiator core, a radiator cap, a fan and other components.

[0003] Since the working environment and driving environment of forest fire trucks are different from those of ordinary cars, the radiator equipped in its engine compartment must also be different from ordinary radiators in some performance aspects, such as shock absorption. However, the radiators with shock absorption effect at present are such as the integrated water tank radiator with expansion tank disclosed in the existing patent CN202222975889.8, and the horizontal remote water tank radiator disclosed in CN209512592U. Although such radiators have shock absorption effect, the shock absorption direction is single, and most of them only have shock absorption design in the up and down directions, so their shock absorption performance still needs to be improved; in addition, water tank radiators now mostly adopt integrated design, which is more difficult to install. A quick-connect positioning design is adopted, but the shock absorption corresponding to different designs is not much different, which affects the actual shock absorption effect. Therefore, the quick connection structure and the shock absorption structure need to be designed in a coordinated manner to improve the balance and reliability of the radiator in the engine compartment; secondly, there are three main types of radiator cores: tube-belt radiator cores, tube-fin radiator cores and plate radiator cores. The first two are the most widely used and the cooling tubes of the radiator core mostly adopt an oblate cross-section design. In actual use, although a filtering structure is installed in the engine compartment to control the inlet and outlet water sides, once scale falls off and enters the cooling tube, the uniform surface can easily cause impurities to swirl and rise in the cooling tube, affecting the discharge efficiency of impurities.

DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Examples, such as Figures 1-14As shown, the present invention provides a radiator for a forest fire truck, comprising a radiator body 1 and a fan assembly 8. The radiator body 1 includes, from top to bottom, a water inlet chamber 11, a water outlet chamber 12, a tube-and-belt radiator core 13, and a radiator cover 14. The tube-and-belt radiator core 13 includes side covers 131, between which are disposed an upper perforated plate 132, a lower perforated plate 133, and several cooling tubes 134 and a heat dissipation belt (not shown). The heat dissipation belt is arranged between adjacent cooling tubes 134 in a Z-folded manner. The fan assembly 8 is located on the rear side of the radiator body 1 and includes at least two fans, which are used to enhance the heat dissipation performance of the radiator when the forest fire truck is operating outdoors. The fan assembly 8 is also provided with multiple grilles to transmit unidirectional airflow, further improving the heat dissipation performance in the engine compartment.

[0021] In order to improve the quick clamping performance and shock absorption performance of the present device, at least two pairs of clamping arms 2 are provided on both sides of the radiator body 1 provided by the present invention. The clamping arms 2 are used to clamp with the positioning rods 3 provided in the engine compartment of the forest fire truck. Radiator suspension components 4 are provided on both sides of the radiator body 1. The radiator suspension components 4 are used to quickly position and clamp the radiator core. A plurality of shock absorbing components 5 are provided below the radiator body 1. The shock absorbing components 5 are used to reduce the vibration of the radiator body 1 in the left, right, and up and down directions. The shock absorbing components 5 include a fixing plate 51 connected to the radiator body 1. The fixing plate 51 is provided with a plurality of support openings 511 that are staggered and inverted up and down. The support openings 511 are provided with horizontal holes 512 and inclined holes 513 , positioning columns 514 are provided in the horizontal hole 512 and the inclined hole 513, and a balance spring 52 is sleeved on the positioning column 514. A U-shaped part 53 is provided on the side of the fixing plate 51, which contacts and cooperates with the two balance springs 52 in the horizontal hole 512 and the inclined hole 513 at the same time. A circular part 54 is provided on the outer side of the U-shaped part 53 and fully surrounds it. One end of the circular part 54 is provided on the square tube 55, and a plurality of mounting holes 551 are provided on the square tube 55. A shock-absorbing spring 56 is provided in the mounting hole 551, and the bottom of the shock-absorbing spring 56 contacts the inner bottom surface of the square tube 55. The bottom of the square tube 55 is provided with a mounting rod 552 corresponding to the mounting hole 551 one by one, and the mounting rod 552 is connected to the mounting bracket 6 set in the engine compartment.

[0022] Specifically, the fan assembly 8 and radiator body 1 can be installed into the front end of the engine compartment from top to bottom, with the clamping arm 2 clamped onto the positioning rod 3 to form a clamping relationship. The radiator suspension assembly 4 can quickly clamp onto the top of both sides of the radiator body 1 to establish a clamping relationship. The bottom of the radiator body 1 is supported by the mounting bracket 6, so this device can be quickly assembled with the engine compartment of the forest fire truck. Furthermore, regarding the shock absorber assembly 5, the edge of its support opening 511 is inclined. On the one hand, it can cross the water outlet pipe installed in the water outlet chamber 12, ensuring the reliability of the water outlet pipe connection; on the other hand, it allows the two ends of the U-shaped member 53 to move in a plane between the horizontal hole 512 and the inclined hole 513. More specifically, the two ends of the U-shaped part 53 cooperate with the balance spring 52 in the horizontal direction and the balance spring 52 in the inclined direction respectively. Since the fixing plate 51 is fixedly connected to the radiator body 1, when the radiator body 1 vibrates, the U-shaped part 53 will also be displaced. At the same time, under the restriction of the top and side edges of the circular part 54, the angle of the U-shaped part 53 will also change. For example, the position change of the U-shaped part 53 caused by horizontal vibration will be subject to the elastic force in the up and down directions after its position change, thereby buffering the horizontal vibration of the radiator body 1; the position change of the U-shaped part 53 caused by up and down vibration will be subject to the elastic force in the horizontal direction after its position change, thereby buffering the up and down vibration of the radiator body 1. In addition, there is the shock-absorbing effect of the shock-absorbing spring 56 and the restriction of the radiator suspension assembly 4 on the top of the radiator body 1, which can effectively improve the shock-absorbing performance of the device. Therefore, the shock-absorbing function of the shock-absorbing component 5 can act on multiple directions of the radiator body 1, balance the vibration of the radiator body 1 in the up, down, left and right directions, narrow the vibration range, shorten the balancing time, and improve the shock-absorbing performance of the device under outdoor sports conditions of forest fire trucks.

[0023] like Figure 14 As shown, in order to improve the flexibility of the dynamic cooperation between the U-shaped member 53 and the two balancing springs 52, the U-shaped member 53 provided by the present invention includes a U-shaped balancing rod 531. Each end of the balancing rod 531 is provided with a slider 532 that rotatably cooperates therewith. The slider 532 is provided with a blind hole 533 that contacts and connects with the end of the balancing spring 52. The support opening 511 is provided with a guide hole 515 that flexibly cooperates with the slider 532 and the balancing rod 531. The balancing rod 531 is limited in position by the side of the circular member 54 on one side of the horizontal hole 512, and by the top of the circular member 54 on the other side of the balancing rod 531 on the other side of the inclined hole 513. The vibration of the balancing rod 531 and the limiting effect of the circular member 54 allow the slider 532 to relatively smoothly complete the corresponding displacement movement in the guide hole 515, thereby allowing the shock absorber assembly 5 to complete real-time buffering adjustment.

[0024] like Figure 11-13As shown, the fixing plate 51, balancing spring 52, and U-shaped member 53 of the shock-absorbing assembly 5 can be pre-assembled with the radiator body 1, while the circular member 54, square tube 55, and mounting rod 552 of the shock-absorbing assembly 5 are pre-assembled with the mounting bracket 6. This facilitates the relative movement of the two parts during the vibration buffering adjustment process to better buffer vibrations. To facilitate assembly, the circular member 54 provided by the present invention includes a limit plate 541, the width of which is greater than the length of the balance bar 531, and a through hole 542 for the balance bar 531 to be assembled into place from top to bottom. The length of the through hole 542 is less than the horizontal width of the balance bar 531. The limit plate 541 is provided with a flap 543 hinged to the limit plate 541 through a door leaf. The flap 543 is L-shaped and its opening faces downward. The end of the flap 543 is provided with a fastening bolt 544, which cooperates with a fastening hole 545 provided at the end of the limit plate 541. Among them, the limiting plate 541 serves as the main limiting structure of the balance bar 531. After the angle of the balance bar 531 is slightly deflected, it can be installed into the through-opening 542 during the assembly process together with the radiator body 1. The balance bar 531 can automatically stretch after entering the limiting range and the natural stretching width is greater than the length of the through-opening 542, so as to reduce the pressure between the balance bar 531 and the flap 543 during the movement of the forest fire truck; the flap 543 can form a fastening relationship with the limiting plate 541 through the fastening bolt 544, and the flap 543 performs a sealing effect on the through-opening 542. Even if the fastening bolt 544 breaks, the probability of both sides of the balance bar 531 passing through the through-opening 542 at the same time is not 100%, so it also has a certain insurance effect.

[0025] To improve the reliability of the connection between the flap 543 and the limiting plate 541, the present invention provides a flap 543 with an upper portion equal to the width of the opening 542, a lower portion wider than the opening 542 and substantially equal to the side surface of the limiting plate 541, and fastening bolts 544 positioned at a position on the flap 543 where it is wider than the opening 542. This allows the hinges between the flap 543 and the limiting plate 541, along with the fastening bolts 544, to form a spatial support system, improving the stability of the flap 543. Furthermore, the penetration point of the fastening bolts 544 does not interfere with the balancing range of the balancing bar 531, and the two limiting surfaces of the balancing bar 531 are substantially smooth, thereby ensuring the proper operating performance of the shock-absorbing assembly 5.

[0026] like Figure 5 、 Figure 6 and Figure 9As shown, the radiator suspension assembly 4 provided by the present invention includes a fixing slot 41, which is installed in the engine compartment, with the slot opening of the fixing slot 41 facing the radiator body 1, and a positioning flip slot 43 connected to it through a rotating shaft 42 is provided in the slot opening of the fixing slot 41, and a torsion spring connected to the positioning flip slot 43 and the opening of the fixing slot 41 is provided on the rotating shaft 42, and one side of the positioning flip slot 43 protrudes from the outside of the slot opening of the fixing slot 41, and a slot-shaped hook 45 is provided on the inner side of the positioning flip slot 43, and the end of the slot-shaped hook 45 cooperates with the side hole plate 46 provided on the side cover 131, and the side hole plate 46 is provided with a plurality of waist-shaped holes 461 evenly distributed along its vertical length direction. The radiator suspension assembly 4 is a pre-assembled component in the engine compartment and is assembled with the radiator body 1 in steps. During the top-down assembly of the radiator body 1, the side cover 131 squeezes the top corner of the positioning flip slot 43, causing the positioning flip slot 43 to rotate about the rotation axis 42. This rotational action causes the fixed slot 41 to flip to the inside of the fixed slot 41. When the positioning flip slot 43 is not under pressure, the positioning flip slot 43 and the slot hook 45 are reset under the action of the torsion spring. The slot hook 45 then passes through the waist-shaped hole 461 on the side hole plate 46 until the radiator body 1 is assembled in place. The position of the waist-shaped hole 461 with which the slot hook 45 cooperates is determined and a barbed relationship is formed. The top corner position of the positioning flip slot 43, the barbed position of the slot hook 45, and the clamping relationship between the clamping arm 2 and the positioning rod 3 can effectively limit the vertical range of movement of the radiator body 1, thereby ensuring the stability of the radiator body 1.

[0027] Furthermore, the end of the slotted hook 45 has a certain margin of fit with the waist-shaped hole 461, thus achieving a certain degree of cushioning within a relatively small range. The slotted hook 45 adopts a slot-shaped design, with the ends of its two side surfaces formed into barbed hook structures. This ensures both the structural strength of the slotted hook 45 itself and a certain span over the waist-shaped hole 461, thereby ensuring the elastic suspension performance of the radiator suspension assembly 4 on the radiator body 1. Furthermore, the width of the slotted hook 45 provided by the present invention is smaller than the width of the positioning and flipping groove 43. A pair of tension springs 47 are disposed at the bottom of the slotted hook 45. The tension springs 47 are connected to the fixed groove 41 in a V-shaped manner. The fixed groove 41 is provided with a door plate hole 48 through which the slotted hook 45 can flip. In this way, the tension springs 47 cooperate with the torsion spring to provide a corresponding elastic force between the slotted hook 45 and the positioning and flipping groove 43. In particular, after the positioning and flipping groove 43 is passively flipped, it can automatically enter the engaging position, thereby engaging and positioning the inner edge of the side cover 131.

[0028] In order to improve the balance performance of the device, a balancing fork 7 is provided below the radiator suspension assembly 4 provided by the present invention. The balancing fork 7 is used to buffer the vibration of the radiator body 1 in the up and down directions.

[0029] Specifically, if Figure 4 、 Figure 8and Figure 10 As shown, the balancing fork 7 includes two C-shaped portions 71 that engage with the positioning rod 3. A spring plate 72 with hyperbolic sides is disposed between the C-shaped portions 71. The arc length of the side of the spring plate 72 facing the radiator body 1 is greater than the arc length of the other side facing away from the radiator body 1. A spring foot 73 is disposed at the end of the spring plate 72. The end of the spring foot 73 is triangular, and its two sides are used to engage with the waist-shaped hole 461. The C-shaped portion 71 serves as a mounting node for the entire balancing fork 7. The two arcuate edges of the spring plate 72 can produce corresponding tension and compression under the pressure of the spring foot 73. The two oblique edges of the spring foot 73 can produce a certain amount of slip within the waist-shaped hole where it is located, causing the balancing fork 7 to generate a reaction force in response to the vibration of the radiator body 1. This reaction force acts on the radiator body 1, thereby improving the overall shock absorption performance of the device.

[0030] In order to improve the immediacy of the elastic deformation of the spring plate 72, the balancing fork 7 provided by the present invention is provided with a pair of shear openings 74 symmetrically distributed up and down on the side facing the radiator body 1. By providing the shear openings 74, the force characteristics on the long side of the balancing fork 7 can be changed, so that it can produce reasonable deformation, which is beneficial to improving the shock absorption performance of the device.

[0031] like Figure 8 As shown, the cooling pipe 134 provided by the present invention includes a straight-line segment 1341, with a cylindrical segment 1342 disposed at the end thereof in communication therewith. The diameter of cylindrical segment 1342 is greater than the width of straight-line segment 1341. This cylindrical segment 1342 changes the conventional oblate-round design of cooling pipe 134, creating a certain inflection in the inner wall of cooling pipe 134. This reduces the path for impurities to swirl and rise within cooling pipe 134, facilitating their movement toward exhaust and subsequent filtration by filtering equipment located elsewhere in the engine compartment. This reduces the likelihood of clogging in the tube-and-belt radiator core 13.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
