Description

Technical Field

[0001] This utility model belongs to the field of vehicle engineering technology, specifically relating to an integrated engine and liquid cooling device and a vehicle. Background Technology

[0002] Traditional heavy-duty vehicles are typically equipped with separate engine radiators and hydraulic retarder radiators. The engine radiator is responsible for dissipating the heat generated by engine combustion and friction. The retarder generates a large amount of heat during operation and requires a separate radiator for cooling; its coolant circuit is usually isolated from or partially isolated from the engine cooling circuit.

[0003] Therefore, currently, two independent radiators are usually placed at the front and rear of the vehicle, respectively. This takes up valuable space, restricts the design of the cab to be moved back and the design of the air intake grille, increases wind resistance, and the dual cooling system also increases the amount of piping, brackets and coolant, significantly increasing the weight of the vehicle. Utility Model Content

[0004] To address the shortcomings of existing technologies, an integrated engine and liquid radiator cooling device and vehicle are provided to solve the problem of complex cooling system structure in vehicles equipped with liquid radiators.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An integrated engine and liquid-cooled cooling device, comprising: A heat dissipation device, wherein a liquid outlet and an engine outlet are provided on one side of the heat dissipation device, and a liquid inlet and an engine inlet are provided on the other side; A pipeline assembly, which is connected in series with the outlet of the retarder and the outlet of the liquid retarder, the inlet of the liquid retarder and the inlet of the retarder; A protective groove is provided on both sides of the heat dissipation device, and the protective groove covers the liquid slurry outlet, engine outlet, liquid slurry inlet and engine inlet. Two protective plates are respectively connected to the outside of the protective grooves on both sides; Two support components are respectively disposed on the outer middle part of the protective plate; An active ventilation device is installed on one side of the heat dissipation device.

[0006] Compared with existing technologies, the above technical solutions have the following beneficial effects: By setting the sump coolant outlet, engine coolant outlet, sump coolant inlet, and engine coolant inlet on the same radiator, both the sump coolant and engine can be cooled simultaneously using the same radiator. The sump coolant and engine are connected in parallel, and the cooling of the engine and sump coolant does not affect each other. In addition, to facilitate the reinforcement and fixation of the radiator, the protective grooves on both sides of the radiator can fix the entire radiator. The protective grooves can also cover the water inlets. The protective plate can cover and connect multiple protective grooves to form a whole. Then, the support component in the middle of the outer side of the protective plate can be used to fix it to the frame. Compared with the previous method of fixing it at the bottom of the entire radiator, the middle fixation is more stable.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, the opening of the protective groove is arranged facing both sides of the heat dissipation device, forming a receiving space with both sides of the heat dissipation device, and a plurality of reinforcing connecting cylinders are provided on the two side walls of the protective groove.

[0008] The containment space formed by the protective groove can not only accommodate the water inlet, but also allow other interfaces connected to the heat dissipation device to be connected to the heat dissipation device through the containment space. The reinforcing connecting cylinder connected in the protective groove can enhance the overall structural strength of the protective groove.

[0009] In one embodiment, through holes are provided on both sides of the protective groove corresponding to the reinforcing connecting cylinder, and the two sides of the connecting plate are folded over to cover the two sides of the protective groove, with connecting holes provided on both sides of the connecting plate corresponding to the through holes.

[0010] To facilitate the connection and installation of the protective groove and the protective plate, the hollow structure of the connecting cylinder is used to insert fasteners and connect them to the connecting holes on both sides of the protective plate. After the protective plate is folded over, it covers the protective groove, which has good stability. At the same time, the corresponding connecting holes and through holes facilitate connection and fixation.

[0011] In one embodiment, the support assembly includes two spaced-apart support seats, the bottom of which is connected to the outside of the protective plate, and the top of which is bent away from the heat dissipation device to form a connecting portion. The two sides of the connecting portion are respectively provided with buffer pads for connecting and fixing to the vehicle frame.

[0012] The spaced support seats can be clamped and fixed on the upper and lower sides of the longitudinal beam of the frame, thus providing a stable connection and fixation.

[0013] In one embodiment, the pipeline assembly includes a pipe, with the two ends of the pipe connected to the liquid retarder inlet and the retarder inlet, respectively. A water valve and a water pump are connected in series in the pipe, and several fixed supports are provided on the pipe at intervals.

[0014] In one embodiment, the heat dissipation device includes a heat dissipation tank and an intercooler, the intercooler being disposed above the heat dissipation tank, and a baffle plate being disposed around the periphery of the intercooler.

[0015] The heat dissipation effect of the intercooler can be enhanced by the baffle plate surrounding the intercooler.

[0016] In one embodiment, an expansion tank is also included, which is connected to the heat dissipation tank.

[0017] This embodiment also discloses a vehicle that includes an engine and a liquid cooling system as described above. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1 like Figure 1-2 As shown, the present invention provides an integrated engine and liquid cooling device, which includes: a cooling device 1, a pipeline assembly 2, a protective groove 3, a protective plate 4, two support assemblies 5, and an active ventilation device 6.

[0027] The cooling device 1 has a liquid retard outlet 101 and an engine outlet 102 on one side, and a liquid retard inlet 103 and an engine inlet 104 on the other side. At the same time, inlet and outlet ports for connecting the liquid retard and the engine are opened on both sides of the cooling device 1, so that the engine and the liquid retard can be cooled through the cooling device 1. The pipeline assembly 2 is used to connect the outlet of the retarder and the liquid retard outlet 101, the liquid retard inlet 103 and the retarder inlet in series.

[0028] The pipeline assembly 2 includes a pipe 201, which can be a flexible or rigid pipe. Specifically, the outlet of the retarder and the outlet of the liquid retarder are directly connected through the pipe 201. At the same time, a water valve 202 and a water pump 203 are connected in series in the pipe 201 between the inlet of the retarder and the inlet 103 of the liquid retarder. The water valve 202 and the water pump 203 are used to control the heat dissipation of the retarder. Several fixed supports 204 are provided at intervals on the pipe 201. The fixed supports 204 can fix the pipe 201 to the vehicle frame.

[0029] Protective grooves 3 are provided on both sides of the heat dissipation device 1. Multiple protective grooves 3 can be provided on each side of the heat dissipation device 1. The protective grooves 3 cover the liquid slurry outlet 101, engine outlet 102, liquid slurry inlet 103, and engine inlet 104. The heat dissipation device 1 typically has pipes 201 leading out from the side, so the water inlets need to be led out from the side. Therefore, providing protective grooves 3 on the side of the heat dissipation device 1 can protect each water inlet within them, while allowing the water inlets to be led out from the side of the protective grooves 3. The protective grooves 3 also serve a protective function for the bent water inlet connecting pipes.

[0030] Two protective plates 4 are respectively connected to the outside of the protective grooves 3 on both sides. The protective plates 4 can cover the protective grooves 3 again, which can further strengthen them, and at the same time connect the outside to form a whole.

[0031] Two support components 5 are respectively disposed on the outer middle of the protective plate 4. By placing the support components 5 on the outer side of the protective plate 4 that forms an integral whole, the overall stability of the support components 5, the protective plate 4, the protective groove 3, and the heat dissipation device 1 is good.

[0032] The active ventilation device 6 can be implemented by fans. Multiple fans are correspondingly arranged on one side of the heat dissipation device 1 to play the role of active ventilation and heat dissipation, effectively ensuring that the heat dissipation device 1 operates at full power.

[0033] By setting a liquid slug outlet 101, an engine outlet 102, a liquid slug inlet 103, and an engine inlet 104 on the same cooling device 1, the liquid slug outlet and engine can be cooled simultaneously using the same cooling device 1. The liquid slug outlet and engine are connected in parallel, and the cooling of the engine and liquid slug outlet does not affect each other. In order to facilitate the reinforcement and fixation of the cooling device 1, the protective grooves 3 on both sides of the cooling device 1 can fix the entire cooling device 1. At the same time, the protective grooves 3 can cover the outlets. The protective plate 4 can cover and connect multiple protective grooves 3 to form a whole. Then, the support component 5 at the middle of the outer side of the protective plate 4 can fix it to the vehicle frame. Compared with the previous method of fixing the entire cooling device 1 at the bottom, which is to add a fixing seat to the bottom of the radiator and put the entire bottom of the radiator on the vehicle frame, since the liquid slug outlet and engine need to be cooled at the same time, the size of the radiator needs to be effectively increased. Therefore, if the enlarged cooling device 1 is only fixed at the bottom, it will be unstable due to the increased center of gravity. It is estimated that setting the support component 5 in the middle can ensure that the overall fixation of the cooling device 1 is more stable.

[0034] The protective groove 3 can be made of channel steel or the like. The groove opening of the protective groove 3 is set facing both sides of the heat dissipation device 1, forming a receiving space 7 with both sides of the heat dissipation device 1. Specifically, the protective groove 3 can be fixed to both sides of the heat dissipation device 1 by welding. Several reinforcing connecting cylinders 8 are provided on the two side walls of the protective groove 3. The reinforcing connecting cylinders 8 are located inside the protective groove 3. At the same time, the two ends of the reinforcing connecting cylinders 8 are connected and fixed to the inner side of the side wall of the protective groove 3, which plays the role of reinforcing the interior of the protective groove 3.

[0035] Since the protective groove 3 is provided in multiple sections, each section of the protective groove 3 is provided with at least two reinforcing connecting cylinders 8, which are located inside the protective groove 3 near both ends.

[0036] The receiving space 7 formed by the protective groove 3 can not only accommodate the water inlet, but also other interfaces connected to the heat dissipation device 1 can be connected to the heat dissipation device 1 through the receiving space 7. The reinforcing connecting cylinder 8 connected in the protective groove 3 can strengthen the overall structural strength of the protective groove 3.

[0037] Since the reinforcing connecting cylinder 8 is cylindrical and hollow inside, through holes 10 are provided on both sides of the protective groove 3 corresponding to the reinforcing connecting cylinder 8, so that the two sides of the protective groove 3 can pass through the reinforcing connecting cylinder 8 through the through holes 10. The two sides of the connecting plate are folded over and covered on both sides of the protective groove 3. Connecting holes 11 are provided on both sides of the connecting plate corresponding to the through holes 10. The connecting holes 11 provided at the positions of the through holes 10 can connect and fix the two sides of the protective plate 4 to the protective groove 3 to form a whole.

[0038] Specifically, to facilitate the connection and installation of the protective groove 3 and the protective plate 4, fasteners are inserted through the hollow structure of the connecting cylinder and connected to the connecting holes 11 on both sides of the protective plate 4. The fasteners can be bolts or the like. At the same time, the interior of the reinforcing connecting cylinder 8 is also filled with a cylindrical shock absorber 9. The outer wall of the cylindrical shock absorber 9 is tightly fixed to the inner wall of the reinforcing connecting cylinder 8. The hollow area of ​​the cylindrical shock absorber 9 is used to insert the fasteners. At this time, a certain amount of movement margin can be achieved between the heat dissipation device 1 and the protective plate 4 to avoid damage caused by hard connection. After the protective plate 4 is folded over, it covers the protective groove 3, and the contact area is large, making the connection more three-dimensional and stable. At the same time, the connecting holes 11 correspond to the through holes 10, which facilitates connection and fixation.

[0039] In this embodiment, the support assembly 5 includes two spaced-apart support seats 501. The bottom of the support seat 501 is connected to the outside of the protective plate 4, and the top of the support seat 501 is bent away from the heat dissipation device 1 to form a connecting part 502. The two sides of the connecting part 502 are respectively provided with buffer pads 503 for connecting and fixing to the frame. Specifically, after fasteners pass through the buffer pads 503, the connecting part 502, and the buffer pads 503, they are connected and fixed to the frame. With the spaced-apart support seats 501, the two support seats 501 can clamp and fix to the upper and lower sides of the frame longitudinal beam, playing a role in stable connection and fixation. Therefore, the two support assemblies 5 include four support seats 501 connected to the frame, which increases the number of connection points and improves stability.

[0040] In this embodiment, the heat dissipation device 1 includes a radiator 105 and an intercooler 106. A liquid slurry outlet 101 and an engine outlet 102 on one side, and a liquid slurry inlet 103 and an engine inlet 104 on the other side are respectively disposed on both sides of the radiator 105. The intercooler 106 is disposed above the radiator 105. A baffle 107 is disposed around the intercooler 106. The baffle 107 surrounding the intercooler 106 can enhance the heat dissipation effect of the intercooler 106.

[0041] The protective grooves 3 are respectively located on both sides of the radiator 105 and the intercooler 106.

[0042] In this embodiment, an expansion tank 12 is also included, which is connected to the heat dissipation tank 105.

[0043] Example 2 This embodiment also discloses a vehicle that includes an engine and a liquid cooling system as described in Embodiment 1 above.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
