[0038] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples and are intended to explain the present application, and should not be understood as limiting the present application.

[0039] As shown in Figure 1 and Figure 2 , the intercooler in the present embodiment is used in a large-bore engine, which refers to a large engine with a bore of more than 150 mm. The intercooler includes a shell 100 and a core 200. The shell 100 defines a receiving cavity 110, and the core 200 is located in the receiving cavity 110.

[0040] It can be understood that the intercooler of the present disclosure can also be used in a small-bore engine.

[0041] The specific cross-sectional shape of the receiving cavity 110 is set according to the core 200. Optionally, the cross-sectional shape of the core 200 can be square, circular, etc. The present embodiment is described by taking the square cross-sectional shape of the core 200 as an example.

[0042] Please refer to Figure 2 and Figure 3 , the core 200 includes a body 210 and a sealing member 220, the sealing member 220 is connected with the body 210 and located between the body 210 and the shell 100. The sealing member 220 functions to seal between the shell 100 and the body 210.

[0043] Optionally, the sealing member 220 extends in a first direction, and the first direction is the installation direction of the core 200 in the receiving cavity 110. For ease of description, the present embodiment defines the direction close to the inlet 112 of the receiving cavity 110 as the outer side, and the direction away from the inlet 112 of the receiving cavity 110 as the inner side.

[0044] Specifically, when installing the core 200, the core 200 is pushed into the receiving cavity 110 from the outer side to the inner side like a drawer. When disassembling the core 200, the core 200 is pulled out from the inner side to the outer side of the receiving cavity 110.

[0045] In the embodiment, the sealing member 220 comprises a mounting strip 221 and a sealing strip 222. The mounting strip 221 is fixed on the body 210, and the sealing strip 222 extends in the first direction to facilitate replacement of the sealing member 220. The sealing strip 222 is fixed on the mounting strip 221 by means of fasteners such as screws.

[0046] Exemplarily, the sealing strip 222 is made of flexible rubber material to improve the sealing effect of the body 210 and the shell 100 by deforming the sealing strip 222.

[0047] For ease of illustration, the embodiment defines the upper and lower directions of the body 210 to describe the position of the sealing member 220. The upper and lower inner walls of the accommodating cavity 110 are sealing surfaces. In use, the intercooler abuts against the sealing surfaces by means of the sealing strip 222 to form a sealing effect.

[0048] Exemplarily, the embodiment is provided with the sealing member 220 on each of the upper and lower sides of the body 210, which is conducive to ensuring the sealing performance of the sealing member 220 and the shell 100.

[0049] In the installation process of the intercooler, the core 200 is hoisted into the accommodating cavity 110 of the shell 100 by means of a lifting appliance. Specifically, the lifting appliance is of a C-shaped structure. The lifting appliance hoists the core 200 from the side of the core 200 and then pushes the core 200 into the accommodating cavity 110 from the position of the inlet 112 of the accommodating cavity 110 to achieve installation of the core 200.

[0050] As shown in Figures 2-4 , the intercooler in the embodiment further comprises a guide assembly 300. The guide assembly 300 is arranged between the shell 100 and the core 200 and is used to guide the movement of the core 200 in the first direction in the accommodating cavity 110. The guide assembly 300 can constrain the movement track of the core 200 in the installation process, avoid deviation of the core 200 from the sealing surface during installation, and simultaneously has the effect of protecting the sealing member 220, avoiding collision between the core 200 and the shell 100, and being conducive to ensuring the sealing performance of the intercooler.

[0051] As an alternative, the guide assembly 300 comprises a first guide member 310 and a second guide member 320 that cooperate with each other, as shown in Figure 2 .

[0052] In some embodiments, the first guide member 310 is arranged on the body 210, and the second guide member 320 is arranged on the shell 100. The first guide member 310 and the second guide member 320 extend in the first direction, so as to guide the movement of the core 200 in the first direction by cooperation of the first guide member 310 and the second guide member 320.

[0053] In some embodiments, the first guide is arranged on the housing 100, and the second guide is arranged on the body 210. The first guide and the second guide extend along the first direction, and the movement of the core 200 along the first direction is guided by the cooperation of the first guide and the second guide.

[0054] In some embodiments, the first guide and the second guide are arranged on the housing 100 and the body 210 respectively. The first guide on the body 210 cooperates with the second guide on the housing 100, and the first guide on the housing 100 cooperates with the second guide on the body 210.

[0055] In some embodiments, the first guide 310 is a sliding rail 311 or a pulley, which is suitable for different application requirements and is conducive to expanding the application range of the intercooler.

[0056] When the first guide 310 is a sliding rail 311, the first guide 310 and the second guide 320 are in sliding cooperation. When the first guide 310 is a pulley, the first guide 310 and the second guide 320 are in rolling cooperation.

[0057] Optionally, the first guide 310 is detachably connected with the body 210, so as to facilitate replacement of the first guide 310. During installation of the core 200, the first guide 310 slides in the guide groove 3211 of the second guide 320, which is easy to cause wear or collision of the first guide 310. The first guide 310 can be replaced for maintenance.

[0058] Please refer to Figure 4 Optionally, the second guide 320 includes two guide rails 321 which are opposite and spaced apart. The space between the two guide rails 321 is defined as the guide groove 3211, and the first guide 310 is slidably or rollably cooperated with the guide groove 3211. During installation of the core 200, the structure of the second guide 320 facilitates alignment of the first guide 310 and the guide groove 3211, which is conducive to improving the installation efficiency.

[0059] Specifically, when the first guide 310 is a sliding rail 311, the first guide 310 and the guide groove 3211 are slidably cooperated. When the first guide 310 is a pulley, the first guide 310 and the guide groove 3211 are rollably cooperated, and the first guide 310 rolls in the guide groove 3211 along the first direction by means of the pulley.

[0060] Further, the guide rail 321 comprises a first guide portion 3212 and a second guide portion 3213. The first guide portion 3212 extends along the first direction, and the second guide portion 3213 is connected to the first end of the first guide portion 3212 close to the inlet 112 of the accommodating cavity 110. The distance between the opposite inner sides of the two second guide portions 3213 gradually increases from the first end in the direction close to the inlet 112 of the accommodating cavity 110, thereby forming an outer-large-inner-small guide slot 3211 structure, which can provide a wider distance for the alignment of the first guide 310 and the guide rail 321 when the core 200 is initially installed, and gradually enter the guide area of the first guide portion 3212 during the advancement of the core 200 into the accommodating cavity 110. The guide rail 321 structure facilitates the installation of the core 200, and is conducive to reducing the labor intensity and cost of the installation process.

[0061] Optionally, the second guide portion 3213 can be an arc-shaped structure, so that the transition of the first guide 310 is more gentle when moving in the guide slot 3211 formed by the constraint of the two arc-shaped second guide portions 3213, which is conducive to avoiding the occurrence of jamming.

[0062] In some embodiments, the second guide portion 3213 can also be a straight line structure.

[0063] Optionally, on the lower end surface of the body 210, the guide assembly 300 is two groups, and the two groups of guide assemblies 300 are respectively arranged on the two sides of the sealing member 220, thereby supporting the body 210 on the two sides of the sealing member 220, further avoiding the collision between the sealing member 220 and the shell 100, avoiding the damage of the sealing member 220, and being conducive to improving the safety of the sealing member 220.

[0064] Optionally, two groups of guide assemblies 300 are respectively arranged on the upper and lower end surfaces of the body 210, thereby further improving the guiding effect on the installation process of the core 200.

[0065] In order to facilitate the replacement of the second guide 320, the guide assembly 300 further comprises a fixing member 330, which fixedly connects the second guide 320 with the shell 100 or the body 210, so that the second guide 320 is an independent structure and is convenient to replace.

[0066] Exemplarily, the fixing member 330 can be a screw, a pin, etc. Both the screw and the pin are commonly used fixing members 330, and have a relatively simple structure, which is convenient to install and disassemble.

[0067] As Figure 5As shown, the distance between the surface of the second guide 320 facing away from the lower inner wall of the shell 100 and the surface of the second guide 320 facing the core 200 is a first distance X, and the length of the fixing member 330 is greater than the first distance, so as to ensure that even if the fixing member 330 is loosened, it cannot fall off the second guide 320, which is beneficial to improve the safety performance of the intercooler. As an example, since the intercooler is applied to the engine, and the engine inevitably has a jolt and other working conditions during use. This working condition can cause the fixing member 330 to loosen and then fall off the second guide 320. When the length of the fixing member 330 is greater than the first distance, even if the fixing member 330 is loosened, it cannot fall into the gap between the core 200 and the shell 100.

[0068] As shown in Figure 3 and Figure 4 As an optional solution, the intercooler further comprises a pad 400 connected to the lower outer wall of the core 200, and the pad 400 is used to abut against the shell 100 when the core 200 is installed at the entrance 112 of the accommodating cavity 110. During the initial installation of the core 200, when the core 200 is located at the entrance 112 of the accommodating cavity 110, the pad 400 can abut against the shell 100 to support the core 200, which facilitates the alignment of the positions of the first guide 310 and the guide groove 3211, and is beneficial to improve the efficiency of installing the core 200.

[0069] As an example, the pad 400 is a non-metal block with a rounded structure, so as to avoid rigid collision between the pad 400 and the shell 100.

[0070] Optionally, the pad 400 is detachably arranged on the core 200, so as to facilitate replacement when the pad 400 is damaged.

[0071] Optionally, the pad 400 is two, and the two pads 400 are oppositely arranged on the lower outer wall of the core 200, and the two pads 400 are located at one end of the core 200 close to the inner side of the accommodating cavity 110, so that the pad 400 is more easily contacted with the shell 100 when the core 200 is installed at the entrance 112.

[0072] In other embodiments, two pads 400 can also be arranged on the upper outer wall of the core 200 opposite to the lower outer wall of the core 200, so as to prevent the guide assembly 300 from being damaged due to collision caused by misoperation.

[0073] In order to enable the pad 400 to effectively support the core 200 at the entrance 112 of the accommodating cavity 110, the height of the pad 400 is greater than the height of the first guide 310 located on the core 200, and at the same time, the height of the first guide 310 located on the core 200 is greater than the height of the second guide 320 located on the shell 100, so that the pad 400 only plays a supporting role when the core 200 is initially installed.

[0074] The inner lower wall of the shell 100 is provided with a groove 111, after the core 200 is installed into the accommodating cavity 110, the cushion block 400 is spaced apart from the shell 100, so that the cushion block 400 is in a suspended state and no longer contacts the shell 100. This scheme can make the sealing strip 222 abut against the inner wall of the accommodating cavity 110, and ensure that the sealing strip 222 is sealed effectively.

[0075] Optionally, in the first direction, the length of the groove 111 is not less than half of the overall depth of the accommodating cavity 110, so that when the core 200 is installed, the cushion block 400 is suspended as early as possible, and only the guide assembly 300 is used to cooperate to constrain the movement of the core 200.

[0076] In order to make the cushion block 400 suspended, the guide rail 321 does not extend to the innermost side of the accommodating cavity 110, but leaves a distance from the end close to the inner side of the accommodating cavity 110, and the first guide part 3212 is not arranged.

[0077] Now, the installation process of the intercooler will be described. Figures 1-4 The installation process of the intercooler will be described.

[0078] As shown in Figure 1 and Figure 4 , when the core 200 is installed, the operator uses the lifting tool to lift the core 200 to the entrance 112 of the accommodating cavity 110. First, the operator sets the cushion block 400 of the core 200 on the inner wall of the accommodating cavity 110, then the operator aligns the first guide part 310 with the guide groove 3211 between the second guide part 3213, and under the guidance of the second guide part 3213, pushes the core 200 to install it into the accommodating cavity. During the installation of the core 200, the first guide part 310 gradually moves into the guide groove 3211 corresponding to the first guide part 3212, to achieve accurate positioning.
