Description

Technical Field

[0001] This utility model relates to the field of intake manifold technology, and in particular to a liquid-cooled intake manifold. Background Technology

[0002] The intake manifold is the intake pipe from the carburetor or throttle body to the intake manifold of the cylinder head. Its function is to distribute the air-fuel mixture from the carburetor or throttle body to the intake manifold of each cylinder.

[0003] Existing intake manifolds mainly consist of an intake chamber, an intercooler, and an exhaust chamber. The intercooler cools the hot air inside the intake manifold, thereby improving engine combustion efficiency. Currently, most intake manifolds rely solely on the intercooler for cooling. However, the limited cooling efficiency of existing intercoolers results in limited cooling of the hot air inside the intake manifold. Furthermore, the uneven distribution of coolant at the inlet of existing intercoolers leads to inconsistent heat exchange within the cooling core, resulting in inconsistent cooling of the hot air inside the intake manifold. Additionally, engine operation causes vibration in the intake manifold; if the cooling core within the intercooler shifts due to frequent vibration, coolant leakage can occur. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, to provide a liquid-cooled heat dissipation intake manifold with simple structural design and significantly improved cooling efficiency.

[0006] Furthermore, the liquid cooler includes a mounting frame, a heat exchange assembly, a water inlet, a water outlet, and a flow guide plate. The top end of the mounting frame is sealed to the air inlet chamber, and its bottom end is sealed to the air outlet chamber. The heat exchange assembly is disposed inside the mounting frame. The water inlet and water outlet are respectively installed on the front and rear sides of the mounting frame. The flow guide plate is respectively disposed inside the front and rear ends of the mounting frame. The flow guide plate has several flow expansion channels. The water inlet and water outlet are respectively connected to the heat exchange assembly through several flow expansion channels.

[0007] Furthermore, the inner diameter of the flow channel gradually increases towards the heat exchange component.

[0008] Furthermore, the heat exchange assembly includes side plates, crossbars, liquid cooling plates, and heat dissipation fins. Two side plates are provided, spaced apart laterally, and the corners of the two side plates are connected by crossbars. Multiple liquid cooling plates are provided, evenly distributed between the two side plates. The front and rear ends of the liquid cooling plates extend into the flow guide plate, respectively. Flow channels are opened in the liquid cooling plates, and heat dissipation fins are provided between adjacent liquid cooling plates.

[0009] Furthermore, the liquid cooler also includes a distribution plate, which is installed inside the flow guide plate and disposed between the flow expansion channel and the heat exchange assembly; the distribution plate has uniformly distributed through holes.

[0010] Furthermore, the heat exchange assembly also includes a positioning post, which is mounted on a crossbar, and the end of the positioning post away from the crossbar is inserted into a positioning hole provided in the mounting bracket.

[0011] Furthermore, it also includes a deflector plate, which is installed inside the air intake chamber to guide hot air to flow evenly towards the liquid cooler.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, a liquid-cooled intake manifold includes an intake chamber 100, a liquid cooler 200, an exhaust chamber 300, heat dissipation reinforcing ribs 400, and heat dissipation fins 500. The intake chamber 100 is connected to the exhaust chamber 300 through the liquid cooler 200. Several heat dissipation reinforcing ribs 400 are arranged on the bottom outer wall of the exhaust chamber 300. Multiple heat dissipation fins 500 are arranged on the peripheral outer wall of the liquid cooler 200.

[0030] Several heat dissipation reinforcing ribs 400 are arranged on the bottom outer wall of the exhaust cavity 300, which improves the heat dissipation effect of the intake manifold itself, while also enhancing the strength and rigidity of the intake manifold. In conjunction with the arrangement of multiple heat dissipation fins 500 on the peripheral outer wall of the liquid cooler 200, the cooling effect of the liquid cooler 200 itself is improved, thereby significantly improving the cooling efficiency of hot air in the intake manifold.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the liquid cooler 200 includes a mounting frame 210, a heat exchange assembly 220, a water inlet 230, a water outlet 240, and a flow guide plate 250. The top end of the mounting frame 210 is sealed to the air inlet chamber 100, and its bottom end is sealed to the air outlet chamber 300. The heat exchange assembly 220 is disposed inside the mounting frame 210. The water inlet 230 and the water outlet 240 are respectively installed on the front and rear sides of the mounting frame 210. The flow guide plate 250 is disposed inside the front and rear ends of the mounting frame 210. The flow guide plate 250 has several expansion channels 251. The water inlet 230 and the water outlet 240 are respectively connected to the heat exchange assembly 220 through the several expansion channels 251. Specifically, the several expansion channels 251 are evenly distributed along the length of the flow guide plate 250, and the inner diameter of the expansion channels 251 gradually increases towards the heat exchange assembly 220. The front and rear ends of the heat exchange assembly 220 are respectively sealed to the flow guide plate 250.

[0032] like Figure 4 As shown, several expansion channels 251 are provided on the flow guide plate 250, so that the coolant in the water inlet 230 enters the heat exchange component 220 evenly, so that the heat exchange effect of the heat exchange component 220 is consistent, thereby ensuring that the cooling effect of the hot air in the intake manifold is consistent.

[0033] like Figure 3 and Figure 5 As shown, the heat exchange assembly 220 includes side plates 221, crossbars 222, liquid cooling plates 223, and heat dissipation fins 224. Two side plates 221 are provided, spaced apart laterally. The corners of the two side plates 221 are connected by the crossbars 222. Multiple liquid cooling plates 223 are provided, evenly distributed between the two side plates 221. The front and rear ends of the liquid cooling plates 223 extend into the guide plate 250, and liquid flow channels are opened in the liquid cooling plates 223 for coolant circulation. Heat dissipation fins 224 are arranged between adjacent liquid cooling plates 223 to increase the heat exchange area. Specifically, the side plates 221 and crossbars 222 are sealed and abut against the guide plate 250. The liquid flow channels in the liquid cooling plates 223 can be designed in a wavy shape to increase the heat exchange area of ​​the liquid cooling plates 223. The heat dissipation fins 224 are also designed in a wavy shape and abut against the inner side of the adjacent liquid cooling plates 223 to form triangular airflow channels for hot air circulation.

[0034] During operation, hot air enters the intake chamber 100 and enters the exhaust chamber 300 through the airflow channel between adjacent liquid cooling plates 223; at the same time, coolant enters the water inlet 230, enters the liquid flow channel in the liquid cooling plate 223 through the front expansion channel 251, and finally enters the water outlet 240 through the rear expansion channel 251; the hot air passing through the airflow channel and the coolant passing through the liquid flow channel achieve heat exchange.

[0035] Example 2

[0036] To further improve the uniformity of the coolant entering the heat exchange component 220, this embodiment adds a distribution plate 260 based on embodiment 1, such as... Figure 6 As shown, the uniform distribution plate 260 is installed inside the flow guide plate 250 and is located between the flow expansion channel 251 and the heat exchange component 220. The uniform distribution plate 260 has uniformly distributed through holes.

[0037] Example 3

[0038] This embodiment adds a positioning post 225 based on embodiment 1 or embodiment 2, such as Figure 7 and Figure 8 As shown, the positioning post 225 is mounted on the horizontal bar 222, and the end of the positioning post 225 away from the horizontal bar 222 is inserted into the positioning hole 211 inside the mounting bracket 210. The cooperation between the positioning post 225 and the positioning hole 211 limits the heat exchange assembly 220, preventing the heat exchange assembly 220 from moving due to frequent vibration of the intake manifold, thereby ensuring that the heat exchange assembly 220 and the guide plate 250 always remain sealed, thus preventing coolant leakage.

[0039] Example 4

[0040] This embodiment adds a guide vane 600 to embodiment 1, 2, or 3, such as... Figure 9 As shown, the baffle 600 is installed inside the air intake chamber 100 to guide the hot air to flow evenly and fully to the liquid cooler 200.
