Description

Technical Field

[0001] The present application relates to the technical field of engine water cooling systems, and specifically discloses a water supply structure for an engine water cooling system. Background Art

[0002] The cooling system is generally composed of a radiator, a thermostat, a water pump, a water channel, etc. The radiator is mainly responsible for cooling the circulating water, and the thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the water circulation range, and adjusts the cooling capacity of the cooling system to ensure that the engine works within the appropriate temperature range. It usually contains a temperature sensing component that opens or closes the flow of air, gas or liquid through thermal expansion or contraction;

[0003] A pump is a device that uses mechanical energy or other external energy to increase the energy of a liquid, thereby transferring the liquid from one place to another;

[0004] Water flow is achieved through water channels, i.e. water pipes, to achieve water cooling. As we all know, the radiator is mainly responsible for cooling the circulating water and achieving water heat exchange. The water pipes enable water flow into the radiator, and the heat exchange is entirely dependent on the radiator. The working pressure of the radiator is very high.

[0005] In view of this, the inventor proposes a water supply structure for an engine water cooling system. Summary of the invention

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] The figure marks in the drawings of the specification include: water outlet pipe 1, cooling body 2, shell 201, first connection port 202, second connection port 203, baffle 204, chamber 205, cooling ball 206, air outlet 207, connecting pipe 4, second switch valve 5, outlet 6, first switch valve 7, water pump 8, outlet pipe 9, radiator 10, bent pipe 11, guide plate 12, heat conducting rod 13, cooling surface 14, flowing water 15.

[0027] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:

[0028] A water supply structure for an engine water cooling system includes a plurality of circulating water pipes used in the engine water cooling system, wherein the circulating water pipes include a plurality of water inlet pipes, a water outlet pipe 1 and a cooling body 2, wherein the cooling body 2 is used to connect one of the water inlet pipes and the water outlet pipe 1, wherein the water inlet pipes are provided with a single outlet 6 after being connected, wherein the outlet 6 is connected to a radiator 10, wherein the output end of the water outlet pipe 1 is connected to an outlet pipe 9, wherein the outlet pipe 9 is also connected to the radiator 10.

[0029] like Figure 1As shown, the water inlet pipes are arranged up and down, and a connecting pipe 4 is provided at the connection between the upper and lower arrangements. Then, a water inlet is provided at the end of the water inlet pipe away from the outlet 6. The water inlet is connected to a water tank and a water pump 8. The water tank and the water pump 8 provide circulating water. One end of the water inlet pipe is connected to a primary heat exchange structure, and the primary heat exchange structure includes a bend pipe 11 connected to the water inlet pipe, a guide plate 12 provided at the connection between the water inlet pipe and the bend pipe 11, and a heat sink provided inside the bend pipe 11.

[0030] Regarding the primary heat exchange structure: Figure 2 As shown, the guide plate 12 includes a first inclined plate and a second inclined plate, one end of the first inclined plate is fixedly connected to the inner wall of the water inlet pipe, the other end of the first inclined plate is fixedly connected to the second inclined plate, and the free end of the second inclined plate is located inside the elbow 11.

[0031] Specifically: After the engine is started, hot water enters the water inlet pipe, then flows from top to bottom, and finally is discharged from the outlet 6 and connected to the radiator 10. In this process, the water flows through the first inclined plate and the second inclined plate into the inner part of the bent pipe 11, such as Figure 2 As shown, the heat sink includes a cooling plate arranged on the inner wall of the curved pipe 11, the cooling surface 14 of the cooling plate is placed on the inner wall of the curved pipe 11, the heating surface of the cooling plate is placed outside the curved pipe 11, and a plurality of heat-conducting rods 13 are evenly arranged on the cooling surface 14. The heat-conducting rods 13 are convex, and a connecting plate is provided at the bottom of the heat-conducting rods 13, which is connected to the cooling surface 14. The convex heat-conducting rods 13 can increase the contact area between the water flow and the heat-conducting rods 13, thereby accelerating the cold and heat exchange.

[0032] The temperature of the heat conducting rod 13 is lowered by cooling the cooling surface 14, and the water flows in contact with the heat conducting rod 13, and heat exchange is achieved through the heat conducting rod 13. After layer-by-layer heat exchange, the water enters the radiator 10 from the outlet 6. At this time, the pressure of the radiator 10 drops suddenly. Similarly, the device is also applicable to the case where the radiator 10 is damaged.

[0033] like Figure 1 and Figure 3 Shown:

[0034] A first switch valve 7 is provided between the cooling body 2 and the water inlet pipe at the top, and a second switch valve 5 is provided on the water inlet pipe below the water inlet pipe near the top. When the first switch valve 7 is opened, the second switch valve 5 is closed; when the second switch valve 5 is opened, the first switch valve 7 is closed.

[0035] The first switch valve 7 and the second switch valve 5 are to prevent the primary heat exchange structure from working simultaneously with the cooling body 2, so that the primary heat exchange structure and the cooling body 2 can be applied to different working conditions and can be flexibly selected.

[0036] About Cooling Body 2:

[0037] like Figure 3 As shown;

[0038] The cooling body 2 includes a shell 201 with a cavity, a first connection port 202 and a second connection port 203 arranged on both sides of the top of the shell 201, a baffle 204 for separating the internal space of the shell 201, and a cooling ball 206 arranged based on the baffle 204, and the first connection port 202 and the second connection port 203 are used to connect the water inlet pipe and the water outlet pipe 1.

[0039] Then, the top of the baffle 204 is fixedly connected to the inner top of the shell 201, and the bottom of the baffle 204 is connected with a connecting rod, the size of the connecting rod is smaller than the internal size of the shell 201, and the free end of the connecting rod is connected to the inner bottom of the shell 201. The baffle 204 and the connecting rod are hollow inside and the baffle 204 and the connecting rod are connected. The baffle 204 is provided with an air outlet 207, and the cooling ball 206 is installed on the baffle 204 at the position of the air outlet 207.

[0040] Specifically: if the cooling body 2 is used, the flowing water 15 enters the cooling body 2. Since the baffle 204 has separated the internal space of the shell 201, the flowing water 15 can only Figure 3 As shown, because the size of the cooling ball 206 is smaller than the inner diameter of the housing 201, the flowing water 15 can only flow from top to bottom. In this flow process:

[0041] The baffle 204 has divided the internal space of the housing 201. For the convenience of introduction, the internal space of the housing 201 is divided into a left chamber 205 and a right chamber 205. Because the size of the connecting rod is smaller than the internal size of the housing 201, the flowing water 15 can only flow from top to bottom, that is, from the left chamber 205 and the right chamber 205;

[0042] In this process:

[0043] The flowing water 15 contacts the cooling ball 206, so in terms of specific connection: it also includes a gas generator, the interior of the gas generator is filled with gaseous coolant, the top of the baffle 204 and the bottom of the connecting rod are both set out of the shell 201, and the output end and the input end of the gas generator are respectively connected to the baffle 204 and the connecting rod set out of the shell 201.

[0044] Specifically: the gaseous coolant diffuses over the entire cooling ball 206 through the gas outlet 207, so that the temperature of the cooling ball 206 becomes lower, and heat exchange is achieved in the process of the flowing water 15 flowing from the left chamber 205 and the right chamber 205;

[0045] Because of the presence of the cooling balls 206, the area of ​​heat exchange is larger, so that heat exchange can be achieved quickly. The flowing water 15 after the heat exchange enters the radiator 10 to achieve cooling of the circulating water.

[0046] The device solves the problem that the cooling pipe in the water supply structure of the traditional engine water cooling system only has the function of water flow but not heat dissipation.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
