DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] The utility model provides an integrated heat dissipation device of an expansion water tank and a radiator water chamber. The heat dissipation device is mainly used in an engine cooling radiator of a vehicle thermal management system and is connected to a radiator core body by welding, riveting and the like.

[0020] like Figure 1-3As shown, an integrated heat dissipation device of an expansion water tank and a radiator water chamber mainly includes an expansion water tank cavity 11 and a radiator water chamber cavity 14. The integrally formed shell 6 is divided into two upper and lower chambers by a middle partition 13, wherein the upper chamber is the expansion water tank cavity 11, and the lower chamber is the radiator water chamber cavity 14. The expansion water tank cavity 11 in the upper half is mainly used to store and replenish the coolant in the engine cooling system. A mounting bracket 1 is provided at one end of the shell 6, and a sensor interface 9 for installing a sensor is provided on the side of the shell 6. The sensor interface 9 is provided with a first fixed threaded hole 4 on the top surface of the shell 6 to monitor the minimum liquid storage level of the expansion water tank, and a second fixed threaded hole 10 is provided on the side of the shell 6. The utility model designs the expansion water tank and the radiator water chamber as an integrated structure, so that the heat dissipation device occupies a small space and has a flexible shape design. In addition, this integrally cast structure simplifies the manufacturing process and reduces the cost.

[0021] like Figure 1 As shown, the shell 6 is provided with a liquid injection port 2, an overflow pipe 3, a return air port 5, an inlet pipe 7 and a water supply pipe 8. Among them, the liquid injection port 2 is arranged at the top of the expansion water tank cavity 11, and is connected to the expansion water tank cavity 11. The liquid injection port 2 is a port for filling the system with coolant, which is connected to the pressure cap; the overflow pipe 3 is vertically arranged on the side of the liquid injection port 2, and is connected to the liquid injection port 2. The overflow pipe 3 is a pipe for discharging gas to the atmosphere when the system pressure is too high; the return air port 5 is arranged at the top of the expansion water tank cavity 11, and is connected to the expansion water tank cavity 11. The outer end of the return air port 5 is connected to the exhaust pipe of the engine; the inlet pipe 7 is arranged on the shell 6 The side of the shell 6 is connected with the radiator water chamber cavity 14. The engine coolant enters the radiator water chamber cavity 14 through the inlet pipe 7 and then flows through the radiator core; the water supply pipe 8 is arranged on the side of the shell 6 and is connected with the expansion water tank cavity 11. The water supply pipe 8 is connected to the inlet of the circulating water pump through a hose to replenish the system. When the temperature of the cooling system is reduced, part of the coolant flows back to the engine cylinder block from the expansion water tank cavity 11 through the water supply pipe 8 to adjust the volume of the coolant and maintain the normal operation of the cooling system. The injection port 2 can also be provided with a sight glass sleeve 12. An exhaust pipe 15 connecting the expansion water tank cavity 11 and the radiator water chamber cavity 14 is provided on the middle partition 13. When the engine is at a high temperature, the coolant expands and enters the expansion water tank cavity 11 through the return air port 5 and the exhaust pipe 15 to prevent the coolant from overflowing from the cooling system. The preferred installation method of the exhaust pipe 15 in this embodiment is as follows Figure 2As shown, an exhaust pipe 15 is provided at each position near both ends of the middle partition 13, one end of the exhaust pipe 15 is fixed to the middle partition 13, and the other end extends to the top of the expansion water tank cavity 11 along a direction perpendicular to the plane of the middle partition 13, and a certain distance is left between the top of the exhaust pipe 15 and the top surface of the expansion water tank cavity 11. The top of the exhaust pipe 15 is preferably designed as an oblique cut structure, and the cut directions of the oblique cuts of the two exhaust pipes are preferably opposite to each other, which is conducive to optimizing the fluid movement in the expansion water tank cavity 11. The utility model is conducive to simplifying the pipeline layout, avoiding additional installation, realizing internal exhaust of the radiator, and avoiding the problems of hose connection leakage and aging.
