[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0028] like Figure 1-4 As shown, an intercooler for a fuel cell engine according to an embodiment of the utility model comprises a heat dissipation body 1, two first frames 2, a second frame 3, a third frame 4 and a mounting assembly 5. The two first frames 2 are correspondingly mounted on both sides of the heat dissipation body 1 along the width direction y of the heat dissipation body 1, and the first frame 1 is provided with a coolant outlet 11 and a coolant inlet 6, which are respectively connected to the heat dissipation body 1; the second frame 3 is mounted on one side of the heat dissipation body 1 along the length direction x of the heat dissipation body 1, and the second frame 3 is provided with an air outlet 7, which is connected to the heat dissipation body 1; the third frame 4 is mounted on the other side of the heat dissipation body 1 along the length direction x of the heat dissipation body 1, and the third frame 4 is provided with an air inlet 8, which is connected to the heat dissipation body 1; the mounting assembly 5 is arranged on the first frame 2 and is used to install the intercooler.

[0029] In this embodiment, the heat dissipation body 1 adopts liquid cooling to dissipate heat. For example, the heat dissipation body 1 includes a shell and a heat dissipation pipe installed in the shell. When working, the two ends of the heat dissipation pipe are connected to the air outlet 7 and the air inlet 8 respectively, and the shell is connected to the coolant outlet 11 and the coolant inlet 6, so that the coolant of the heat dissipation pipe is wrapped, thereby cooling the air in the heat dissipation pipe.

[0030] Based on the above arrangement, the heat dissipation body 1 can be protected by the first frame body 2 , the second frame body 3 and the third frame body 4 , thereby ensuring the safety of use and making the overall installation structure compact.

[0031] like Figure 1 As shown, in one embodiment, the coolant outlet 11 is provided on one of the first frames 2, and the coolant inlet 6 is provided on the other first frame 2. By respectively providing the coolant outlet 11 and the coolant inlet 6 on the two first frames 2, the pipelines are located at different positions during the subsequent pipeline installation process, so that the installation space is larger.

[0032] Specifically, the coolant outlet 11 faces the length direction x of the heat sink 1, and the coolant inlet 6 faces the width direction y of the heat sink 1. During installation, the coolant outlet 11 and the coolant inlet 6 face different directions, which is more conducive to the installation of the pipeline.

[0033] like Figure 2 As shown, two air outlets 7 are provided, and the air outlets 7 face the height direction z of the heat dissipation body 1. The air outlets 7 face the height direction z, and can be staggered with the coolant outlet 11 and the coolant inlet 6, so that the pipeline connected to the air outlet 7 is more convenient to install, avoiding hitting the pipeline connected to the coolant outlet 11 and the coolant inlet 6.

[0034] like Figure 3 As shown, in one embodiment, one end of the third frame body 4 extends out of the heat dissipation body 1 to form a protrusion 41, and the air inlet 8 is provided on a side of the protrusion 41 close to the second frame body 3, and the air inlet 8 faces the length direction x of the heat dissipation body 1. By providing the protrusion 41, the pipeline connected to the air inlet 8 can be installed against the side wall of the first frame body 2, making the structure compact.

[0035] In one embodiment, the intercooler further includes a purge port 9 and a sensor interface 10, which are arranged at both ends of the second frame 3 along the width direction y of the heat dissipation body 1. The purge port 9 is connected to the air outlet 7 and is used to purge the interior of the second frame 3 to prevent excessive hydrogen concentration in the air; the sensor interface 10 is used to install a sensor to monitor the temperature of the air discharged from the air outlet 7.

[0036] In one embodiment, the mounting assembly 5 includes a first mounting seat 51 and a second mounting seat 52, wherein the first mounting seat 51 is disposed on one of the first frames 2, and the second mounting seat 52 is disposed on the other first frame 2. The intercooler is mounted by the first mounting seat 51 and the second mounting seat 52, so that the installation is stable and reliable.

[0037] Specifically, two second mounting seats 52 are provided and are spaced apart along the height direction z of the heat dissipation body 1 . The second mounting seats 52 can fix the intercooler in the height direction z.

[0038] In one embodiment, the length and width of the heat dissipation body 1 are both greater than three times its height, so that the heat dissipation body 1 is flat, compact and occupies little space.

[0039] In one embodiment, two surfaces of the heat dissipation body 1 along the height direction z are respectively flush with the first frame 2, the second frame 3 and the third frame 4, so that the surfaces on both sides of the intercooler are flat, which is convenient for installation and fixing.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
