Description

Technical Field

[0001] This application relates to the field of automotive cooling systems, and more particularly to an automotive coolant reservoir. Background Technology

[0002] The coolant reservoir, also known as an expansion tank or auxiliary coolant tank, is a crucial component of an automotive cooling system, primarily used to regulate coolant volume changes and maintain system pressure balance. In related technologies, a coolant reservoir typically includes a reservoir body and a filler cap. The reservoir body contains a cooling chamber for storing coolant. The reservoir body is equipped with an overflow pipe connected to the vehicle's radiator for supplying coolant to the cooling chamber, and a return pipe also connected to the radiator for supplying coolant out of the cooling chamber. During engine operation, a large amount of heat is generated. The rapid expansion of air within the radiator causes the coolant entering the overflow pipe to carry a significant amount of gas, resulting in the formation of numerous air bubbles within the cooling chamber of the coolant reservoir. Regarding the aforementioned technologies, the inventors believe that these air bubbles, circulating with the coolant, negatively impact the coolant's flow properties and heat dissipation efficiency. Utility Model Content

[0003] In order to improve the heat dissipation efficiency of the coolant reservoir and reduce air resistance, this application provides an automotive coolant reservoir.

[0004] The automotive coolant reservoir provided in this application adopts the following technical solution: An automotive coolant reservoir includes a reservoir body; the reservoir body has a cooling chamber for storing coolant; the reservoir body has an overflow pipe connected to a radiator for supplying coolant into the cooling chamber, and a return pipe connected to the radiator for supplying coolant from the cooling chamber back to the radiator; the overflow pipe includes an output pipe disposed inside the cooling chamber and extending vertically downward, and an outer pipe connected to the upper end of the output pipe and extending outward from the cooling housing; the output pipe is provided with a bubble separation mechanism; the bubble separation mechanism includes a mounting base detachably mounted on the output pipe and a filter screen disposed on the mounting base for dispersing bubbles; the mounting base has an arrangement slot for arranging the end of the output pipe.

[0005] By adopting the above technical solution, when the car engine is running, the coolant expands in volume due to heat. The portion exceeding the radiator capacity flows into the cooling chamber through the overflow pipe for temporary storage. After the coolant temperature drops, its volume contracts, creating a negative pressure in the cooling chamber. The coolant stored in the coolant tank is then drawn back to the radiator through the return pipe. The output pipe is arranged vertically downwards with an air bubble separation mechanism at the lower end. When the coolant is output from the lower end of the output pipe, the filter screen can disperse and reduce air bubbles in the coolant, which helps to improve the heat dissipation efficiency of the coolant tank and reduce air resistance.

[0006] Optionally, the mounting base has a snap-fit ​​structure, which includes a snap-fit ​​groove formed on the side wall of the mounting base, a snap-fit ​​connecting rod arranged along the lower edge of the snap-fit ​​groove and having elasticity, and a snap hook head arranged at the upper end of the snap-fit ​​connecting rod. The output pipe has a snap hook groove for the snap hook head to snap into place.

[0007] By adopting the above technical solution, the buckle head of the snap-fit ​​structure is engaged with the buckle groove of the output tube to achieve a detachable connection between the mounting base and the output tube, which facilitates the installation, disassembly and maintenance of the bubble separation mechanism.

[0008] Optionally, the number of the snap-fit ​​structures is two and they are symmetrically arranged on both sides of the mounting base, and the output tube has two snap-fit ​​grooves for the two snap-fit ​​heads to engage one-to-one.

[0009] By adopting the above technical solution, the two symmetrically arranged snap-fit ​​structures cooperate with the two corresponding snap-fit ​​grooves on the output tube, making the connection between the mounting base and the output tube more stable and helping to improve the reliability of the bubble separation mechanism installation.

[0010] Optionally, the mounting base has an arrangement hole on the side wall of the arrangement slot and a ball spring plunger is installed in the arrangement hole, and the outer side wall of the output pipe has a snap-fit ​​hole for arranging the plunger ball of the ball spring plunger.

[0011] By adopting the above technical solution, the detachable connection between the mounting base and the output tube is achieved by utilizing the cooperation between the ball-head spring plunger and the snap-fit ​​hole, making the installation and disassembly of the mounting base more convenient and facilitating the maintenance and replacement of the bubble separation mechanism.

[0012] Optionally, the number of arrangement holes is two and they are symmetrically arranged on the side wall of the arrangement slot. The ball spring plunger is installed in each of the two arrangement holes, and the output pipe has two snap-fit ​​holes for the two ball spring plungers to engage one-to-one.

[0013] By adopting the above technical solution, the two symmetrically arranged ball-head spring plungers cooperate with the two snap-fit ​​holes on the output tube, making the connection between the mounting base and the output tube more stable and helping to improve the efficiency of installation and disassembly.

[0014] Optionally, the outer wall of the output pipe is provided with an external thread, and the mounting seat is provided with an internal thread on the side wall of the through groove that mates with the external thread.

[0015] By adopting the above technical solution, the installation base and the output pipe are connected by the cooperation of external and internal threads, which makes the installation and disassembly of the installation base simple and facilitates the maintenance and replacement of the bubble separation mechanism. At the same time, the threaded connection has good sealing and stability, which helps to ensure the normal operation of the bubble separation mechanism.

[0016] Optionally, the filter screen has a pore size of 1-3 mm.

[0017] By adopting the above technical solution and setting a filter screen with a pore size range of 1-3mm, bubbles can be dispersed more effectively, which helps to improve the separation efficiency of the bubble separation mechanism, while ensuring the normal circulation and heat dissipation effect of the coolant.

[0018] Optionally, the arrangement groove includes a first ring portion and a second ring portion along the direction away from the output pipe. The inner diameter of the first ring portion is larger than the inner diameter of the second ring portion, and a stepped surface is formed between the first ring portion and the second ring portion. The mounting base is provided with a sealing gasket arranged on the stepped surface for the lower end of the output pipe to abut against.

[0019] By adopting the above technical solution, a specific structure for arranging the through groove is disclosed. The first ring and the second ring form a stepped surface, and a sealing gasket is arranged on the stepped surface so that the lower end of the output pipe abuts against the sealing gasket. This helps to improve the connection sealing between the output pipe and the mounting base, thereby reducing the risk of coolant leakage from the gap between the mounting base and the output pipe.

[0020] Optionally, the cooling chamber includes multiple sub-chambers, and the cooling tank body is provided with multiple partition plates for separating the sub-chambers; the lower part of the partition plate has a liquid passage hole that penetrates the inner and outer surfaces and is used for the flow of coolant, and the upper part of the partition plate has a vent hole that penetrates the inner and outer surfaces and is used for balancing air pressure.

[0021] By adopting the above technical solution, the cooling chamber is divided into multiple sub-chambers, which causes the coolant to form eddies or slow down when flowing into the coolant tank, and flows between the sub-chambers through the liquid passage holes, which is conducive to the uniform distribution and flow of the coolant; the vent holes can balance the air pressure between the sub-chambers, ensure the smooth circulation of coolant, and help improve the working stability of the coolant tank.

[0022] Optionally, the top of the cooling vessel has a feeding port, and the feeding port is provided with a sealing end cap for sealing and closing the feeding port.

[0023] By adopting the above technical solution, the filling port at the top of the cooling tank makes it easy to add coolant into the cooling chamber, and the sealing end cap can seal the filling port, which helps to ensure the airtightness of the cooling chamber and reduce the risk of coolant leakage and debris entering the cooling chamber.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. An automotive coolant reservoir, comprising a reservoir body, an overflow pipe, and a return pipe; when the automotive engine is running, the coolant expands in volume due to heat, and the portion exceeding the radiator capacity flows into the cooling chamber through the overflow pipe for temporary storage. After the coolant temperature drops, its volume contracts, creating a negative pressure in the cooling chamber, and the coolant stored in the reservoir is drawn back to the radiator through the return pipe; the output pipe is arranged vertically downwards and an air bubble separation mechanism is provided at the lower end, so that when the coolant is output from the lower end of the output pipe, the filter screen can disperse and reduce air bubbles in the coolant, which helps to improve the heat dissipation efficiency of the coolant reservoir and reduce air resistance; 2. By setting a snap-fit ​​structure on the mounting base, the snap-fit ​​hook head engages with the snap-fit ​​groove of the output pipe, thereby achieving a detachable connection between the mounting base and the output pipe, which facilitates the installation, disassembly, and maintenance of the bubble separation mechanism; 3. By setting two symmetrically arranged snap-fit ​​structures that cooperate with the corresponding two snap-fit ​​slots on the output tube, the connection between the mounting base and the output tube is made more stable, which helps to improve the reliability of the bubble separation mechanism installation.

[0036] Reference Figure 3 and Figure 4 The cooling tank body 1 is provided with partition plates for dividing the cooling chamber 13 into multiple sub-chambers 131. The partition plates include multiple upper partition plates 111 vertically arranged on the upper housing 11 and lower partition plates 121 vertically arranged on the lower housing 12, each corresponding to one of the upper partition plates 111. The lower edges of the upper partition plates 111 and the upper edges of the corresponding lower partition plates 121 abut against each other. The upper partition plates 111 have vent holes 1111 penetrating the inner and outer surfaces for balancing air pressure.

The lower housing 12 has a return pipe 122 connected to the radiator for allowing coolant to be output from the cooling chamber 13 to the radiator. The return pipe 122 is horizontally arranged at the bottom of the lower housing 12.

The bubble separation mechanism 2 includes a mounting base 21 detachably mounted on the lower end of the output pipe 141 and a filter screen 22 disposed on the mounting base 21 for dispersing bubbles. The mounting base 21 has an arrangement slot 211 for the end of the output pipe 141. The arrangement slot 211 includes a first ring portion 2111 and a second ring portion 2112 in a direction away from the output pipe 141. The inner diameter of the first ring portion 2111 is larger than the inner diameter of the second ring portion 2112, and a stepped surface 2113 is formed between the first ring portion 2111 and the second ring portion 2112.

[0039] The implementation principle of an automotive coolant reservoir according to this application embodiment is as follows: When the car engine is running, the coolant expands in volume due to heat. The portion exceeding the radiator capacity flows into the cooling chamber 13 through the overflow pipe 14 for temporary storage. After the coolant temperature drops, the volume contracts, creating a negative pressure in the cooling chamber 13. The coolant stored in the reservoir 1 flows in the cooling chamber 13 and is drawn back to the radiator through the return pipe 122. The output pipe 141 is arranged vertically downwards and a bubble separation mechanism 2 is set at the lower end. When the coolant is output from the lower end of the output pipe 141, the filter screen 22 can effectively disperse and reduce the bubbles in the coolant, which helps to improve the heat dissipation efficiency of the coolant reservoir and reduce air resistance.

One end of the plunger spring 2162 abuts against the bottom end of the inner cavity of the plunger housing 2161, and the other end abuts against the plunger ball head 2163, so that the plunger ball head 2163 always tends to abut against the opening of the plunger housing 2161. The output pipe 141 has a snap-fit ​​hole 1412 on its outer side wall for arranging the plunger ball head 2163 of the ball-head spring plunger 216. In this embodiment, there are two arrangement holes 215, which are symmetrically arranged on the side wall of the arrangement slot 211.
