If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

[0036] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention. The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0037] Please refer to Figures 1 to 10 This application discloses a fan shroud structure 100 for fixing a heat exchanger 200. The fan shroud structure 100 includes a body 1 and a fixing component 2. The body 1 has an assembly space 101, within which the heat exchanger 200 is disposed. The fixing component 2 includes a fixing member 21 and a limiting member 22. The fixing member 21 is disposed on the body 1, and the limiting member 22 is disposed within the assembly space 101, with the fixing member 21 and the limiting member 22 located on opposite sides of the body 1. When the heat exchanger 200 is disposed within the assembly space 101, the fixing member 21 and the limiting member 22 are respectively connected to the heat exchanger 200 to fix the heat exchanger 200 to the body 1. This improves the adaptability of the fan shroud structure 100, thereby reducing costs.

[0038] For ease of explanation, the following definitions are provided. Figure 3 The thickness direction of the wind shield structure 100 shown is the first direction D1-D1, the height direction of the wind shield structure 100 is the second direction D2-D2, and the length direction of the wind shield structure 100 is the third direction D3-D3. The first direction D1-D1, the second direction D2-D2, and the third direction D3-D3 are all perpendicular to each other.

[0039] Please refer to Figures 1 to 6The body 1 includes a vertical wall 11 and a peripheral wall 12 perpendicularly disposed on the vertical wall 11. Specifically, the vertical wall 11 is disposed along a second direction D2-D2, and the peripheral wall 12 is disposed along a first direction D1-D1 on one side of the vertical wall 11. The vertical wall 11 and the peripheral wall 12 form an assembly space 101. A fixing member 21 is disposed on the peripheral wall 12 and protrudes from the peripheral wall 12 along the first direction D1-D1. A limiting member 22 is disposed on the inner wall of the peripheral wall 12. The fixing member 21 and the limiting member 22 are respectively located on opposite sides of the peripheral wall 12. When the heat exchanger 200 is placed in the assembly space 101, the two sides of the heat exchanger 200 in the thickness direction are connected to the fixing member 21 and the limiting member 22 respectively, so that the heat exchanger 200 can be fixed in the body 1, thereby improving the adaptability of the body 1.

[0040] The peripheral wall 12 includes a first peripheral wall 121, a second peripheral wall 122, a third peripheral wall 123, and a fourth axial wall connected end to end. The first peripheral wall 121, the second peripheral wall 122, the third peripheral wall 123, the fourth peripheral wall 124, and the vertical portion form an assembly space 101. The first peripheral wall 121 and the third peripheral wall 123 are arranged opposite each other along a third direction D3-D3, and the second peripheral wall 122 and the fourth peripheral wall 124 are arranged opposite each other along a second direction D2-D2. The outer wall surfaces of the second peripheral wall 122 and the fourth peripheral wall 124 are each provided with two fasteners 21, and the inner wall surfaces of the second peripheral wall 122 and the fourth peripheral wall 124 are each provided with two limiting members 22. Specifically, the two fasteners 21 on the second peripheral wall 122 and the two fasteners 21 on the fourth peripheral wall 124 are arranged opposite each other along the third direction D3-D3. Thus, by setting four fixing parts 21 and four limiting parts 22, the stability of the heat exchanger 200 in the assembly between the body 1 can be improved, and the separation of the heat exchanger 200 from the body 1 can be avoided, thereby affecting the heat dissipation effect.

[0041] Please refer to Figures 3 to 8The limiting member 22 is approximately L-shaped. It includes a base 221 and a limiting portion 222 vertically disposed on the base 221. The base 221 is fixedly connected to the vertical wall 11, and the limiting portion 222 is in contact with the inner wall surface of the peripheral wall 12. The free end of the limiting portion 222 abuts against the heat exchanger 200. Specifically, the base 221 includes a first base 2211 and two second bases 2212 vertically disposed on one side of the first base 2211. The limiting portion 222 is disposed on the other side of the first base 2211. The limiting portion 222 and the two second bases 2212 are arranged back-to-back relative to the first base 2211. The limiting portion 222 includes a first limiting portion 2221 and two second limiting portions 2222 disposed on both sides of the first limiting portion 2221. The second limiting portions 2222 are connected to the first base 2211 to improve the overall structural strength of the limiting portion 222. The first base 2211 also has a positioning hole 201. A positioning boss 111 is provided on the side of the vertical wall 11 facing the assembly space 101. Fasteners pass through the positioning hole 201 and are threadedly connected to the positioning boss 111, so that the limiting member 22 can be fixedly connected to the vertical wall 11.

[0042] Please refer to Figures 3 to 10 The fastener 21 includes a fixing part 211 and a hook part 212 disposed on the fixing part 211. The fixing part 211 is integrally disposed with the peripheral wall 12, and the hook part 212 protrudes from the peripheral wall 12, facing the assembly space 101. The hook part 212 is snapped into the heat exchanger 200. At least a portion of the connection between the fixing part 211 and the peripheral wall 12 has a notch 103. Specifically, at least a portion of the fixing part 211 protrudes from the peripheral wall 12 in a first direction D1-D1, and the notch 103 at the connection between the fixing part 211 and the peripheral wall 12 gives the fixing part 211 a certain elastic force to facilitate the assembly of the heat exchanger 200.

[0043] In the embodiments of this application, the length of the limiting member 22 is 5-100 mm. The length of the limiting member 22 is the distance between the free end of the second fixing part 211 and the free end of the limiting part 222. When the thickness of the heat exchanger 200 is between 12 mm and 36 mm, by selecting a limiting member 22 that is compatible with the heat exchanger 200 to be assembled, the heat exchanger 200 can be assembled and fixed in the body 1. This improves the adaptability of the shroud structure 100.

[0044] Please refer to Figures 1 to 6The vertical wall 11 has ventilation holes 102 that communicate with the assembly space 101. This improves airflow within the assembly space 101, thereby increasing the heat exchange efficiency of the heat exchanger 200. Specifically, the vertical wall 11 is provided with connecting structures 3, multiple connecting structures 3 are disposed around the outer periphery of the ventilation holes 102, and the connecting structures 3 are configured to fix a fan. Each connecting structure 3 includes a first connecting member 31 and a second connecting member 32. Four first connecting members 31 are arranged around the outer periphery of the ventilation holes 102. Two second connecting members 32 are respectively disposed on opposite sides of the ventilation holes 102 in the radial direction. By providing the first connecting members 31 and the second connecting members 32, the fan can be secured to the vertical wall 11, and the fan can be turned on to improve the heat exchange efficiency of the heat exchanger 200.

[0045] This utility model also discloses a heat exchange system, including a fan shroud structure 100, a heat exchanger 200, and a fan. The heat exchanger 200 in this application is a microchannel heat exchanger 200, which is disposed within the installation space of the body 1 and fixed within the body 1 by a fixing member 21 and a limiting member 22. A fan is disposed on the side of the vertical wall 11 away from the assembly space 101. The fan blows air onto the heat exchanger 200 within the assembly space 101 through the ventilation holes 102 of the vertical wall 11 to improve the heat exchange efficiency of the heat exchanger 200. By using the fan structure disclosed in this utility model, the compatibility with the heat exchanger 200 can be improved, and costs can be reduced.

[0046] In summary, this application discloses a fan shroud structure 100 for fixing a heat exchanger 200. The fan shroud structure 100 includes a body 1 and a fixing component 2. The body 1 has an assembly space 101, within which the heat exchanger 200 is disposed. The fixing component 2 includes a fixing member 21 and a limiting member 22. The fixing member 21 is disposed on the body 1, and the limiting member 22 is disposed within the assembly space 101, with the fixing member 21 and the limiting member 22 located on opposite sides of the body 1. When the heat exchanger 200 is disposed within the assembly space 101, the fixing member 21 and the limiting member 22 are respectively connected to the heat exchanger 200 to fix it to the body 1. This improves the adaptability of the fan shroud structure 100, thereby reducing costs.
