Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 is a sectional view of a cooler integrated with an automatic temperature control valve according to an embodiment of the present application; Figure 2 is a sectional view of a cooler integrated with an automatic temperature control valve according to an embodiment of the present application, when the automatic temperature control valve is in an open state.

[0032] An embodiment of the present invention provides a cooler with an integrated automatic temperature control valve, comprising: a shell 10 and an automatic temperature control valve 20. The shell 10 is provided with a partition plate 14 that divides its inner cavity into a cooling water tank 11, a seawater cooling tank 12 and a water storage tank 13. The automatic temperature control valve 20 can be optionally a wax temperature control valve. The automatic temperature control valve 20 is arranged on the partition plate. The automatic temperature control valve 20 is provided with a low-temperature water channel connecting the cooling water tank 11 and the water storage tank 13. When the temperature of the cooling water in the cooling water tank 11 is not higher than a preset temperature threshold, the cooling water in the cooling water tank 11 can flow into the water storage tank 13 through the low-temperature water channel in the automatic temperature control valve 20. A high-temperature water channel 15 is provided in the partition plate 14 between the cooling water tank 11 and the seawater cooling tank 12. An inlet 122 connected to the high-temperature water channel 15 and an outlet 123 connected to the water storage tank 13 are provided on the side wall of the seawater cooling tank 12. A seawater cooling core 121 is provided in the seawater cooling tank 12. The automatic temperature control valve 20 is used to open when the cooling water temperature in the cooling water tank 11 is higher than a preset temperature threshold to connect the cooling water tank 11 and the high-temperature water channel 15, while closing the low-temperature water channel. At this time, the cooling water in the cooling water tank 11 first enters the high-temperature water channel 15, and then flows into the seawater cooling tank 12. Finally, the cooling water entering the seawater cooling tank 12 is cooled by the seawater cooling core 121. By integrating an automatic temperature control valve 20 in the cooler, when the temperature of the cooling water is low, the cooling water can flow directly to the water storage tank 13 through the low-temperature water channel without being cooled by the seawater cooling tank 12. Only when the temperature of the cooling water is high, the cooling water flows to the seawater cooling tank 12 through the high-temperature water channel 15, and after being cooled by the seawater cooling tank 12, it flows into the water storage tank 13. Therefore, it can prevent the cooling water from being overcooled or overheated, thereby ensuring the cooling effect of the cooler and the stability of the diesel engine operation.

[0033] It should be noted that the automatic temperature control valve 20 belongs to the existing technology, and its working principle can be referred to the existing technology. The purpose of this application is to apply it in the cooler to change the flow path of the cooling water according to the temperature change of the cooling water.

[0034] In some embodiments, the partition plate 14 includes an L-shaped partition plate 141 and a T-shaped partition plate 142. The L-shaped partition plate 141 and the T-shaped partition plate 142 enclose a high-temperature water channel 15. The inlet 122 is provided on the vertical plate of the T-shaped partition plate 142, and the outlet 123 is provided on the horizontal plate of the T-shaped partition plate 142. The automatic temperature control valve 20 is provided on the horizontal plate of the L-shaped partition plate 141 and the horizontal plate of the T-shaped partition plate 142. Figure 1As shown, the vertical plate of the T-shaped partition 142 is located above the horizontal plate of the T-shaped partition 142. The L-shaped partition 141, the vertical plate of the T-shaped partition 142, and the left portion of the horizontal plate of the T-shaped partition 142 enclose a high-temperature water channel 15. A low-temperature water channel is provided within the automatic temperature control valve 20, which runs from top to bottom. The horizontal plate of the L-shaped partition 141 is provided with an upper mounting hole 1411. The automatic temperature control valve 20 includes a water retaining plate 22 and a center rod 21. The low-temperature water channel is provided within the center rod 21. The center rod 21 is axially slidably connected to the water retaining plate 22, which is located on the horizontal plate of the L-shaped partition 141. The outer diameter of the section of the center rod 21 located below the water retaining plate 22 is smaller than the upper mounting hole 1411. When the water temperature in the cooling water tank 11 is not higher than the preset temperature threshold, the center rod 21 is in its initial position. When the temperature of the cooling water in the cooling water tank 11 is higher than the preset temperature threshold, the center rod 21 automatically moves upward so that the upper end of the center rod 21 is pressed against the inner top of the cooling water tank 11. At the same time, the cooling water in the cooling water tank 11 enters the high-temperature water channel 15 through the gap between the upper mounting hole 1411 and the center rod 21.

[0035] Furthermore, in order to increase the flow rate of cooling water, multiple automatic temperature control valves 20 are provided on the partition plate 14. For example, two automatic temperature control valves 20 can be set on the horizontal plate of the L-shaped partition 141. In addition, when one of the automatic temperature control valves 20 fails, the other automatic temperature control valve 20 can still ensure its automatic opening and closing function.

[0036] In some embodiments, a lower mounting hole 1421 is provided on the horizontal plate of the T-shaped partition 142, and a sealing ring 1422 is provided between the outer periphery of the lower end of the center rod 21 and the lower mounting hole 1421. For example, a sealing ring groove can be provided in the lower mounting hole 1421, and the sealing ring 1422 can be placed in the sealing ring groove. The sealing ring 1422 can prevent cooling water from flowing from the lower mounting hole 1421 into the water tank 13.

[0037] In some embodiments, the upper mounting hole 1411 is a stepped hole, the water retaining plate 22 is located on the stepped surface of the stepped hole, the outer diameter of the section of the center rod 21 below the water retaining plate 22 is smaller than the minimum outer diameter of the stepped hole, and the lower surface of the water retaining plate 22 contacts the stepped surface of the stepped hole to prevent cooling water from flowing downward from the stepped hole into the high-temperature water channel 15. When the temperature of the cooling water is not higher than a preset temperature threshold, the center rod 21 is in an initial position, and the cooling water does not flow out from between the water retaining plate 22 and the center rod 21; when the temperature of the cooling water is higher than the preset temperature threshold, the center rod 21 moves upward, and the gap between the center rod 21 and the water retaining plate 22 increases, and the cooling water flows through the gap into the high-temperature water channel 15.

[0038] In some embodiments, the upper mounting hole 1411 is a tapered hole with a gradually reduced inner diameter from top to bottom, and the outer periphery of the central rod 21 is provided with a tapered section with a gradually reduced outer diameter from top to bottom, when the central rod 21 is in the initial position, the tapered section and the tapered hole are in contact with each other, which can effectively prevent the cooling water from flowing out of the upper mounting hole 1411 downward, when the temperature of the cooling water in the cooling water tank 11 is higher than the preset temperature threshold, the central rod 21 moves upward, the gap between the tapered section and the tapered hole increases, at this time, the cooling water can flow from the gap to the high-temperature water channel 15.

[0039] In some embodiments, the upper end of the cooling water tank 11 is provided with an opening, and the opening is provided with a cover plate 112, wherein the cover plate 112 is preferably detachably connected to the opening, for example, connected by bolts, when assembling, the cover plate 112 can be opened to facilitate the installation of the automatic temperature control valve 20 on the partition plate 14. The lower end of the cover plate 112 is provided with a protrusion 1121 corresponding to the upper end of the central rod 21, when the central rod 21 moves upward, the upper end of the central rod 21 abuts against the lower surface of the protrusion 1121 to block the low-temperature water channel in the central rod 21.

[0040] In some embodiments, the water storage tank 13 is provided with a water baffle 132 corresponding to the outlet end of the low-temperature water channel provided in the automatic temperature control valve 20, and a gap is left between the water baffle 132 and the outlet end of the low-temperature water channel. As shown in Figure 1 The left side of the water storage tank 13 is provided with a water baffle 132 extending to the right, the lower end of the automatic temperature control valve 20 on the left side corresponds to the water baffle 132, and the lower end of the horizontal plate of the T-shaped partition plate 142 is provided with an L-shaped water baffle 132, which can block the cooling water flowing out of the low-temperature water channel to prevent the cooling water from impacting the inner bottom surface of the shell 10, thereby protecting the shell 10 and improving the service life of the cooler.

[0041] In some embodiments, the cooling water tank 11 is provided with a cooling water inlet 111 on the side away from the seawater cooling tank 12, and the bottom end of the water storage tank 13 is provided with a cooling water outlet 131. As shown in Figure 1 The left side of the cooling water tank 11 is provided with a cooling water inlet 111, and the right side of the bottom end of the water storage tank 13 is provided with a cooling water outlet 131, and the cooling water outlet 131 and the outlet of the seawater cooling tank 12 are arranged staggered with each other, and the cooling water flowing out of the cooling water outlet 131 will eventually flow back to the cooling water inlet 111.

[0042] In some embodiments, a water level sensor 124 is provided on the upper portion of the seawater cooling tank 12. The water level sensor 124 can be located on the top plate of the seawater cooling tank 12 or on an upper sidewall of the seawater cooling tank 12. The water level sensor 124 can detect the level of cooling water in the seawater cooling tank 12. When the water level is low, the water level sensor 124 can generate an alarm signal to remind the user to refill water.

[0043] In actual use, the cooler is installed on the diesel engine, and the cooling water of the diesel engine enters the cooling water tank 11 through the pipeline. When the temperature of the cooling water is low, the automatic temperature control valve 20 is in the initial position, and the cooling water can enter the water storage tank 13 from the low-temperature water channel in the automatic temperature control valve 20. The flow direction of the cooling water is as follows: Figure 1 As shown by the arrow in the figure; when the temperature of the cooling water is high, the automatic temperature control valve 20 is opened, and the low-temperature water channel is closed. The cooling water can enter the high-temperature water channel 15 from the cooling water tank 11, and then enter the seawater cooling tank 12 for cooling, and finally flow into the water storage tank 13. The flow direction of the cooling water is as shown in FIG. Figure 2 As shown by the arrow in .
