Description

Technical Field

[0001] The present application relates to the technical field of engine accessories, and in particular to an engine water outlet pipe with high torque and high heat dissipation. Background Art

[0002] When the engine is working, a large amount of heat is generated, and coolant needs to be set around it to take away the excess heat to prevent the engine from being damaged due to overheating. The coolant needs to be connected to the cooler through a water outlet pipe connected to the engine to achieve a cooling cycle. The existing water outlet pipe is covered on the outside of the engine drainage end through a clamp structure. Although it can remain stable due to the friction of the rubber, when the engine is working at high power, such as high torque output, the engine heats up faster and the vibration intensity is higher. In addition, the coolant will adaptively accelerate and give the water pipe a stronger impact force. Under this condition, the probability of the water outlet pipe loosening will increase. Summary of the invention

[0003] The purpose of the present application is to provide an engine water outlet pipe with a more reliable connection, high torque and high heat dissipation.

[0004] In order to achieve the above objectives, the present application provides a high-torque and high-heat dissipation engine water outlet pipe: comprising a pipe body, the end of the pipe body having a pipe sleeve and an inner liner, the inner liner is located in the pipe sleeve, the pipe body is fixedly connected to a steel ring through the inner liner, and a slot is formed between the outer side surface of the steel ring and the inner wall of the pipe sleeve for plugging with the engine drainage end or the cooler water inlet end.

[0005] As a preferred embodiment, the cross-section of the pipe body is a circular ring, and the pipe sleeve and the liner are coaxial with the annular end face of the pipe body, so as to facilitate cooperation with most cylindrical drainage ends and water inlet ends.

[0006] As a preference, the outer side surface of the end of the pipe sleeve has a clamping edge, which is suitable for preventing the clamp sleeved outside the pipe sleeve from slipping off and limiting the position of the clamp structure outside the pipe sleeve.

[0007] As a preferred embodiment, two clamping edges are provided at both ends of the pipe sleeve, and a clamping groove is formed between the two clamping edges at the same end, so as to further improve the stability of the clamping structure outside the pipe sleeve.

[0008] As a preferred embodiment, the pipe sleeve and the inner liner are an integrated structure with the pipe body and are made of rubber material with uniform material and good structural stability.

[0009] Preferably, the inner wall of the lining is provided with an embedded groove, and the end face of the steel ring has an embedded ring suitable for being inserted and fixed in the embedded groove to ensure the connection stability of the steel ring.

[0010] Preferably, the embedded ring is coaxial with the steel ring, the outer diameter of the embedded ring is smaller than the outer diameter of the steel ring, and a convergence groove is formed between the outer side surface of the embedded ring and the end face of the steel ring for fitting with the thinned part of the lining, thereby making the inner wall of the slot smooth and continuous.

[0011] As a preference, the steel ring is made of stainless steel, and the end of the steel ring facing away from the liner is also located in the pipe sleeve, ensuring that the steel ring can be fully inserted into the drainage end or the water inlet end.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) A steel ring structure that can be embedded in the drainage end of the engine is provided at the connection end of the water outlet pipe. The thermal expansion characteristics of the steel ring are utilized. When the engine is working at high torque, the steel ring is tightly engaged with the inner wall of the drainage end by hard contact, thereby dispersing the impact force of the coolant on the rubber pipe sleeve, effectively improving the connection stability of the water outlet pipe, and reducing the probability of falling off when the engine is working at high power. The water outlet pipe has higher reliability;

[0014] (2) The connection end of the water outlet pipe has a double-layer structure. The drainage end of the engine or the water inlet end of the cooler can be inserted between the double-layer structures at the end of the water outlet pipe. When the inner steel ring expands and fits tightly against the inner wall of the drainage end of the engine or the water inlet end of the cooler, even accelerated coolant cannot overflow, and the water outlet pipe has better sealing performance.

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0027] like Figure 1-7The high-torque and high-heat dissipation engine water outlet pipe shown includes a curved pipe body 1, and the end of the pipe body 1 has a pipe sleeve 101 and an inner liner 102. The outer diameter of the pipe sleeve 101 is approximately the same as the outer diameter of the pipe body 1, and the inner diameter of the inner liner 102 is the same as the inner diameter of the pipe body 1. At the same time, the outer diameter of the inner liner 102 is smaller than the inner diameter of the pipe sleeve 101, so the inner liner 102 is located in the pipe sleeve 101, and the pipe sleeve 101 and the inner liner 102 are an integral structure with the pipe body 1, and are all made of rubber material with good material uniformity, and can flexibly adjust their own extension direction according to the pipe layout position. The cross-section of the pipe body 1 is a circular ring, and the pipe sleeve 101 and the inner liner 102 are coaxial with the annular end face of the pipe body 1. The pipe sleeve 101 and the inner liner 102 are both cylindrical, and the length of the inner liner 102 along the axial direction is only about one-fifth of that of the pipe sleeve 101, and the length of the inner liner 102 is shorter than that of the pipe sleeve 101, so as to reserve sufficient configuration space for other components.

[0028] The pipe body 1 is fixedly connected with the steel ring 2 through the liner 102. It is the metal part of the entire water outlet pipe and is made of stainless steel material. It has the characteristics of high structural stability, good corrosion resistance and thermal conductivity, and obvious thermal expansion effect. A slot 105 is formed between the outer side surface of the steel ring 2 and the inner wall of the pipe sleeve 101. The slot 105 extends also to between the pipe sleeve 101 and the liner 102, and is used to be plugged with the drainage end of the engine or the water inlet end of the cooler. After plugging, the clamp structure will be tightened outside the pipe sleeve 101 to ensure the stability of the plug-in. In order to reduce the movement of the clamp structure outside the pipe sleeve 101, the outer side surface of the end of the pipe sleeve 101 will have a clamp edge 103, which can effectively prevent the clamp sleeved on the outside of the pipe sleeve 101 from slipping. Usually, there are two clamp edges 103 at both ends of the pipe sleeve 101, and a clamp groove 104 is formed between the two clamp edges 103 at the same end, and the clamp structure is clamped in the clamp groove 104.

[0029] The end of the steel ring 2 facing away from the liner 102 is also located in the pipe sleeve 101, that is to say, the length of the steel ring 2 is also smaller than the length of the pipe sleeve 101, in order to prevent the steel ring 2 from being too long and causing the engine drainage end or the cooler water inlet end to be unable to be fully inserted into the slot 105. An embedded groove 106 is provided on the inner wall of the liner 102, and an embedded ring 201 is provided on the end face of the steel ring 2, which is just inserted and fixed in the embedded groove 106. It is usually fixed by applying curing glue on the outer side of the embedded ring 201, which can not only ensure stability but also have good sealing performance. The embedded ring 201 is coaxial with the steel ring 2, and the two have the same inner diameter, but the outer diameter of the embedded ring 201 is smaller than the outer diameter of the steel ring 2. A convergence groove 202 is formed between the outer side surface of the embedded ring 201 and the end face of the steel ring 2, which just fits with the thinned part of the liner 102, so that the outer side surface of the steel ring 2 is flush with the outer side surface of the liner 102, and the inner wall of the slot 105 will be smoother.

[0030] Working principle: When in use, one end of the water outlet pipe is plugged into the drainage end of the engine and the other end is plugged into the water inlet end of the cooler until the slot 105 is fully inserted, and the pipe sleeve 101 is clamped to the outside of the drainage end or the water inlet end with a clamp structure, and the steel ring 2 is located inside the drainage end or the water inlet end. When the engine starts, the engine body heats up and transfers heat to the steel ring 2. The outer diameter of the steel ring 2 expands and can fit closely to the inner wall of the drainage end of the engine, effectively reducing the risk of falling off due to increased body vibration and increased coolant flow rate when the engine is working at high torque.

[0031] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
