Embodiment Construction

[0026] The thermal management module of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] figure 1 A perspective view showing a rotary valve of a thermal management module of the prior art. Such as figure 1 As shown, the rotary valve V of the thermal management module in the prior art has multiple channels, for example, three channels. The channel has openings such as opening 1 , opening 2 and opening 3 . Each of opening 1 , opening 2 and opening 3 is symmetrical with respect to the corresponding cross-section of rotary valve V . In other words, each of the opening 1 , the opening 2 and the opening 3 is bilaterally symmetrical in the axial direction of the rotary valve V. As shown in FIG. The opening 1 and the opening 2 are arranged successively in the circumferential direction of the rotary valve, and the opening 3 is arranged on one side of the opening 1 and the opening 2 in the axial direction of the rotary val...

Abstract

The invention provides a heat management module and a rotation valve thereof. The heat management module comprises a shell (6) provided with an opening, the rotation valve (V) arranged in the shell (6) and provided with a channel and a sealing assembly arranged in the opening of the shell (6); the channel is communicated to the outside through the opening of the shell (6); the sealing assembly comprises a main sealing piece (7), an auxiliary sealing piece (8) and a sealing piece support (9), the sealing piece support (9) is provided with a cylindrical part (92) and a flange (91), and the main sealing piece (7) and the auxiliary sealing piece (8) are sequentially arranged in space defined by the flange and the cylindrical part of the sealing piece support and the shell (6) in the axial direction of the opening; the main sealing piece (7) is in contact with the rotation valve in the axial direction of the opening, and the auxiliary sealing piece (8) is used for sealing between the shell (6) and the sealing piece support (9); and the main sealing piece (7) is in loose fit to the sealing piece support (9) and is in loose fit to the interior of the shell (6).

Description

technical field [0001] The present application relates to a thermal management module and a rotary valve thereof. Background technique [0002] Thermal management modules and the like for engines are well known. The thermal management module can accurately control the engine temperature to reduce the warm-up time, improve the efficiency of the engine, transmission and turbocharger, etc., and help to improve the efficiency and service life of vehicle components. [0003] For example, patent document DE 10 2013 209 582 A1 discloses a thermal management module. The thermal management module has a plurality of rotary valves and seals for sealing the rotary valves. The rotary valve is arranged in the casing of the thermal management module to rotate therein, and the rotary valve has a plurality of circular outlet openings to communicate with cooling passages outside the casing. A seal is arranged between the outlet opening of the rotary valve and the housing and is spring-load...
