Description

Technical Field

[0001] The utility model belongs to the technical field of thermal management, and relates to an anti-misalignment positioning structure for installing a plate heat exchanger in an automotive thermal management integrated module. Background Technique

[0002] The plate heat exchanger of the automotive thermal management integrated module and the coolant flow channel plate often adopt an end face sealing structure (the sealing ring is assembled into the groove of the coolant flow channel plate, and the installation bottom plate of the plate heat exchanger is a plane). When assembling the plate heat exchanger, an anti-misalignment positioning structure needs to be set.

[0003] The currently commonly used anti-misalignment positioning structure is to set positioning rib retaining walls in at least two directions on the coolant flow channel plate. However, the positioning rib retaining wall structure is prone to inaccurate positioning, resulting in inconvenient assembly, skewing of the plate heat exchanger, and a risk of leakage. At the same time, when using a manipulator to automatically assemble bolts, the equipment is prone to alarm for failed bolt assembly and tightening, affecting production efficiency, thereby increasing the rework cost.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0026] Please refer to Figures 1 to 4, it is an anti-misalignment positioning structure for the installation of a plate heat exchanger in an automotive thermal management integrated module, including a coolant flow channel plate 2 and a plate heat exchanger installation bottom plate 1 installed on the coolant flow channel plate 2. The plate heat exchanger installation bottom plate 1 is provided with a precise positioning circular hole D1 and a rough positioning strip hole D2, and the coolant flow channel plate 2 is provided with a precise positioning post Z1 and a rough positioning post Z2 corresponding to the precise positioning circular hole D1 and the rough positioning strip hole D2. The precise positioning circular hole D1 and the precise positioning post Z1 are in clearance fit, and the diameter of the rough positioning post Z2 is larger than the diameter of the precise positioning circular hole D1.

[0027] In this embodiment, through the cooperation of the precise positioning circular hole D1 and the rough positioning strip hole D2 with the precise positioning post Z1 and the rough positioning post Z2, and by limiting the diameter of the rough positioning post Z2 to be larger than the diameter of the precise positioning circular hole D1, the rough positioning post Z2 cannot be assembled into the precise positioning circular hole D1, which can play an anti-misalignment role. Then, through the clearance fit between the precise positioning post Z1 and the precise positioning circular hole D1, precise positioning can be completed to achieve the purpose of installation positioning.

[0028] Secondly, by setting the rough positioning strip hole D2 as a strip hole structure, the difficulty of installing and positioning the plate heat exchanger installation bottom plate is reduced, thereby accelerating the installation efficiency.

[0029] Furthermore, in this embodiment, the precise positioning circular hole D1 and the rough positioning strip hole D2 are respectively arranged at both ends of the plate heat exchanger installation bottom plate.

[0030] On the plate heat exchanger installation bottom plate 1, there are also a first installation through hole K1, a second installation through hole K2, a third installation through hole K3, and a fourth installation through hole K4. Corresponding plate heat exchanger installation threaded holes are provided on the coolant flow channel plate 2 to complete the installation and fixation of the plate heat exchanger.

[0031] As Figures 1 to 3 shown, the first installation through hole K1 and the second installation through hole K2 are arranged at one end of the plate heat exchanger installation bottom plate 1, and the third installation through hole K3 and the fourth installation through hole K4 are arranged at the other end of the plate heat exchanger installation bottom plate 1. Let the center distance between the third installation through hole K3 and the fourth installation through hole K4 be W1, the center distance between the first installation through hole K1 and the second installation through hole K2 be W2, the center distance between the first installation through hole K1 and the third installation through hole K3 be L1, and the center distance between the second installation through hole K2 and the fourth installation through hole K4 be L2. And at least one set of numerical values of the two sets of dimensions of L1 and L2, W1 and W2 are not equal to play an anti-misalignment role during installation.

[0032] Specifically, in this embodiment, the central connection line of the first mounting through-hole K1 and the third mounting through-hole K3 is parallel to the central connection line of the second mounting through-hole K2 and the fourth mounting through-hole K4, and the central connection line of the first mounting through-hole K1 and the third mounting through-hole K3 is perpendicular to the central connection line of the first mounting through-hole K1 and the second mounting through-hole K2.

[0033] Furthermore, the outer shape of the plate heat exchanger mounting base plate 1 is set as an asymmetric structure to further achieve the purpose of preventing misinstallation. In this embodiment, a U-shaped groove is provided at the outer edge of one end of the plate heat exchanger mounting base plate 1, so that the outer shape of the plate heat exchanger mounting base plate 1 is an asymmetric structure.

[0034] In another embodiment, the central connection line of the first mounting through-hole K1 and the third mounting through-hole K3 and the central connection line of the second mounting through-hole K2 and the fourth mounting through-hole K4 are arranged non-parallelly, and the central connection line of the first mounting through-hole K1 and the third mounting through-hole K3 and the central connection line of the first mounting through-hole K1 and the second mounting through-hole K2 can also be set as non-perpendicular, and the anti-misinstallation effect is further improved through the misaligned arrangement of the mounting through-holes; the outer shape of the plate heat exchanger mounting base plate 1 can also be set as a symmetric structure.

[0035] The utility model can realize anti-misinstallation and precise positioning of plate heat exchangers and similar installation products, has a simple structure, can improve the installation production efficiency, improve the product reliability, reduce the manufacturing cost, and at the same time can reduce the installation rework cost.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit them. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions, and they should all be covered by the scope of the claims of the utility model.
