Problems solved by technology
[0011] Furthermore, assembly operations involving such deformations of the male connection flanges become complicated
These deformations make the operator's job more difficult if the assembly is done manually, and they make it impossible to perform assembly on a robotic assembly line, where the robot cannot adapt its movements to each situation as the operator can

Embodiment Construction
[0039] To clearly detail the connecting flanges, in Figure 3 to Figure 6 A trihedral LVT is shown in , in order to identify the longitudinal direction L, the vertical direction V and the transverse direction T.
[0040] In addition, the designations "first" and "second" mentioned in the description do not represent quantitative concepts, but enable to distinguish specific elements appearing twice in the present invention.
[0041] figure 1 A cooling arrangement 1 for an electrical storage device 2 is shown. The assembly notably has a heat exchange member 4 , in this case in the form of a plate heat exchanger 6 , configured to be pressed onto a housing 8 housing an electrical storage device such as an electrochemical cell. The heat exchanging member is configured to be passed by 1234yf or R134a type refrigerant.
[0042] The cooling assembly also has a connection assembly 10 for leading the refrigerant to the heat exchange component, which has inter alia pipes 12 and flange...

The invention relates to a connection interface (20) for a connection assembly (10) for connecting refrigerant tubes in a cooling assembly of a motor vehicle electrical storage device, the connection assembly (10) comprising at least one flange (18) made integral with a heat exchange member (4), said connection interface (20) being arranged at end portions (24) of refrigerant fluid tubes to be connected to said heat exchange member, characterised in that the connection interface (20) comprises a first portion (50) integral with the end of each of the tubes (12) and a second portion (52) mounted freely around the tubes, the second portion comprising openings (64, 66) for passing the tubes dimensioned to allow a clearance for relative movement therebetween of the two portions (50, 52) of the connection interface (20), at least in a plane perpendicular to a direction of elongation of the end portions of the tubes, the connection interface (20) being configured to engage with a securing member (36) capable of setting the position of the two portions relative to each other.
Description
technical field [0001] The present invention relates to an assembly for cooling an electrical storage device, and more particularly, to a connecting device for connecting refrigerant pipes. Background technique [0002] Electric and hybrid vehicles are equipped with electrical storage devices made up of components of electrical modules which themselves are made up of components of electrochemical cells. [0003] In order to ensure the autonomy, performance, and reliability of such power storage devices, it is necessary to perform heat treatment on the power storage devices. The heat treatment of the electrical storage device is aimed at keeping the temperature of the electrical modules constituting the electrical storage device between approximately 20°C and 40°C. This is because, when the temperature of the electrical module is too low, the capacity of its electrochemical cells decreases, while when the temperature of the electrical module is too high, the service life of ...
