[0002] The heat exchanger assembly includes a heat exchanger and a bracket fixed on the heat exchanger. Refrigerant can flow into the heat exchanger to exchange heat with the coolant (for example, water) in the heat exchanger. Usually, there are two openings on the bracket, which are aligned with the refrigerant inlet and the refrigerant outlet of the heat pipe. The two openings are fixedly installed with connectors protruding from the bracket for connecting the refrigerant block. The refrigerant block is provided with a flange on the other side relative to the bracket for plugging in external components. It can be seen that the refrigerant in the heat exchanger needs to pass through the connector, the refrigerant block and the flange on the refrigerant block to reach the external components, and the flow path is long, which will lead to a decrease in the heat exchange performance of the heat exchanger; moreover, the number of parts connecting the heat exchanger to the external components (such as the aforementioned bracket, connector, refrigerant block, etc.) is large, resulting in excessive weight, high cost, complex installation and large space occupation, which cannot meet the needs of miniaturization of parts.

[0024] The following describes the implementation of the present disclosure through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification.
[0025] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings attached to this specification are only used to match the contents disclosed in the specification for the understanding and reading of those skilled in the art, and are not used to limit the limiting conditions for the implementation of the present disclosure, so they have no substantial technical significance. Any structural modification, change in proportional relationship, or adjustment of size, without affecting the effects and purposes that can be achieved by the present disclosure, should still fall within the scope of the technical contents disclosed by the present disclosure. At the same time, the terms such as "on" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present disclosure. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present disclosure without substantially changing the technical contents.
[0026] In order to more clearly understand the present disclosure, embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0027] The present disclosure provides a support 1 for a heat exchanger 2. Figure 3 to Figure 4 The bracket 1 includes a bracket body 10 and a flange 20. The bracket body 10 has a plate-like form and can be fixed to one side of the heat exchanger 2 (for example, Figure 1 The flange 20 is disposed on the bracket body 10, or in other words, the flange 20 extends from the opening of the bracket body 10 toward a direction away from the bracket body 10. When the bracket 1 is fixedly mounted on the heat exchanger 2, the flange 20 can be connected to / communicated with the first fluid inlet 201 and / or the first fluid outlet 202 (such as Figure 2As shown), the flange 20 is connected to the fluid of the heat exchanger 2, and the flange 20 also has an interface (also referred to as an external component interface) for directly plugging in external components. The flange 20 and the bracket body 10 may be an integrally formed part. In one embodiment, the bracket 1 may be a stamped part formed by a stamping preparation process, so as to facilitate manufacturing and reduce the preparation cost. However, the present disclosure is not limited to this, as long as the flange 20 and the bracket body 10 are an integrally formed part. The above-mentioned setting of the bracket 1 can omit the installation process of each component (for example, omitting the installation of the bracket and the connector in the prior art, etc.), and the flange 20 on the bracket body 10 can be directly plugged into an external component (for example, an expansion valve, etc.), without the need to additionally use the refrigerant block in the prior art, shortening the flow path, reducing the number of parts, making it light in weight and low in cost, and also saving space and reducing installation costs.
[0028] For details, please refer to Figure 3 to Figure 4 The flange 20 may be a generally hollow short tube structure. The flange 20 includes a first flange 21 and a second flange 22, which are disposed at the first end 101 of the support body 10 and are used to connect to the first fluid inlet 201 and the first fluid outlet 202 (such as Figure 2 In one embodiment, the inner diameter of the first flange 21 may be smaller than the inner diameter of the second flange 22. This is because the refrigerant entering the heat exchanger 2 through the first flange 21 has a higher temperature and a greater pressure than the refrigerant leaving the heat exchanger 2 and passing through the second flange 22. Therefore, the inner diameter of the first flange 21 may be smaller than the inner diameter of the second flange 22. However, the present disclosure is not limited thereto. For example, the inner diameters of the first flange 21 and the second flange 22 may be equal, as long as the first flange 21 and the second flange 22 can be connected to the first fluid inlet 201 and the first fluid outlet 202 (as shown in FIG. 2 ) of the heat exchanger 2. Figure 2 Just connect / communicate with each other).
[0029] Please continue to see Figure 3 and Figure 4 The bracket 1 further includes two avoidance grooves 11, which are arranged at the second end 102 of the bracket body 10 and are recessed toward the first end 101, and are used for when the bracket 1 is installed on the heat exchanger 2 (such as Figure 1As shown), the second fluid inlet 203 and the second fluid outlet 204 connected to the heat exchanger 2 are avoided, wherein the second end 102 is arranged opposite to the first end 101. Of course, the present disclosure is not limited thereto, and the bracket 1 may also not include the avoidance groove 11, as long as the bracket 1 and the heat exchanger 2 do not interfere with each other during installation. For example, the bracket 1 includes a right-angle avoidance provided to avoid the second fluid inlet 203 and the second fluid outlet 204. For another example, the bracket 1 does not have a avoidance, but opens a hole to avoid the second fluid inlet 203 and the second fluid outlet 204, and the inner diameter of the hole is greater than or equal to the outer diameter of the second fluid inlet 203 and the second fluid outlet 204.
[0030] The bracket 10 may also include a seal (not shown), which may be a sealing ring, which is sleeved on the outer peripheral wall of the first flange 21 and the second flange 22, so that when the first flange 21 and the second flange 22 are inserted into an external component (such as an expansion valve, etc.), a seal (such as an end face seal) is formed between the bracket 1 and the external component to prevent fluid leakage.
[0031] In one embodiment, the length and width of the bracket 1 may be substantially equal to the length and width of the top cover of the heat exchanger 2 used in conjunction therewith. Figure 1 As shown. However, the present disclosure is not limited thereto. For example, in another embodiment, the length and width of the bracket 1, especially the bracket body 10, may also be greater than the length and width of the top cover of the heat exchanger 2, so that at least one edge of the bracket body 10 protrudes from the side wall of the heat exchanger 2. In other words, the area directly below the at least one edge of the bracket body 10 is in the air, and is not supported by the heat exchanger 2. In this other embodiment, the bracket 1 may also include a mounting hole (not shown), which may be provided at the at least one edge of the bracket body 10, so that the bracket body 10 is fixedly mounted on the vehicle body or other components through the mounting hole and fastening elements such as screws. When multiple edges of the bracket body 10 protrude from the side wall of the heat exchanger 2, the mounting holes may be provided in multiple numbers and arranged around the edges of the bracket body 10, so that the force on the bracket 1 is uniform and stress concentration is avoided.
[0032] The present disclosure also provides a heat exchanger assembly 3. Please refer to Figures 1 to 3 The heat exchanger assembly 3 includes a heat exchanger 2 and a bracket 1 fixed to the heat exchanger 2 and in fluid communication with the heat exchanger 2. One side of the heat exchanger 2 (e.g. Figure 2 A first fluid inlet 201 and a first fluid outlet 202 for the refrigerant to flow in and out, and a second fluid inlet 203 and a second fluid outlet 204 for the coolant (for example, water) to flow in and out are provided on the upper side as shown, so that the refrigerant and the coolant can exchange heat inside the heat exchanger 2.
[0033] The bracket 1 can be fixedly mounted on the heat exchanger 2 by brazing, and the first flange 21 and the second flange 22 of the bracket 1 are aligned with the first fluid inlet 201 and the first fluid outlet 202 of the heat exchanger 2, so that the bracket 1 and the heat exchanger 2 can be fluidically connected. The specific structure of the bracket 1 is as described above, so it will not be repeated here. Since the heat exchanger assembly 3 includes the bracket 1 integrated with the flange 20, the heat exchanger assembly 3 can be directly connected to external components (for example, expansion valve, etc.) through the first flange 21 and the second flange 22, without the need to use the refrigerant block in the prior art, shortening the flow path, reducing the number of parts, making it light in weight, low in cost, and saving space, and easy to install.
[0034] See also Figure 2 and Figure 4 , the heat exchanger assembly 3 may further include a positioning assembly for positioning the relative positions of the bracket 1 and the heat exchanger 2. The positioning assembly may include a positioning protrusion 205 and a positioning groove 12 used in conjunction with each other. In one embodiment, the positioning protrusion 205 is disposed on the top cover of the heat exchanger 2, and correspondingly, the positioning groove 12 is disposed on the side of the bracket 1 facing the heat exchanger 2, and the positioning protrusion 205 is inserted into the positioning groove 12. However, the present disclosure is not limited to this, for example, the positioning protrusion 205 may also be disposed on the bracket 1, corresponding to the positioning groove 12 disposed on the top cover of the heat exchanger 2, as long as the relative positions of the bracket 1 and the heat exchanger 2 can be positioned.
[0035] Although the heat exchanger 2 in the heat exchanger assembly 3 described in the above embodiment of the present disclosure is provided with the first fluid inlet 201, the first fluid outlet 202, the second fluid inlet 203 and the second fluid outlet 204 arranged on the same side (such as Figure 2 The upper side is taken as an example for explanation, however, the present disclosure is not limited to this. For example, the second fluid inlet 203 and the second fluid outlet 204 can also be arranged on the lower side of the heat exchanger 2. In this case, the bracket 1 installed on the upper side of the heat exchanger 2 does not need to be provided with the avoidance groove 11, which can further simplify the structure of the bracket 1.
[0036] The bracket 1 described in the above embodiment of the present disclosure is mainly explained by taking the use with the heat exchanger 2 as an example, but the present disclosure is not limited to this. For example, the bracket 1 can also be used in other occasions where external components need to be plugged in.
[0037] The present disclosure provides a bracket and a heat exchanger assembly including the bracket. By arranging the bracket body and the flange as an integrally formed part, or by integrating the flange on the bracket, the installation process of the bracket and the connector in the prior art can be omitted, and the flange can be directly plugged into an external component (for example, an expansion valve, etc.) without the additional use of a refrigerant block in the prior art, thereby shortening the flow path, reducing the number of parts, making the weight light, the cost low, and also saving space and facilitating installation.
[0038] The above describes exemplary implementations of the bracket and heat exchanger assembly provided by the present disclosure with reference to preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
