Definitions
- the invention relates to the technical field of cooling a heat transfer fluid capturing calories through the passage of conduits in a heat engine or electric.
- the air for cooling the heat transfer fluid is the ambient air generally captured at the calender of the vehicle.
- This document indeed describes a cooling device comprising an inlet and two outputs at different levels.
- a cooling device comprising an inlet and two outputs at different levels.
- Such a device comprises a one-piece structure and is not removable.
- This type of structure can however be problematic under certain conditions of use by generating thermal shocks that can damage the device and cause leaks.
- a first object of the invention is therefore to compensate for expansion phenomena to prevent leakage at the junction between two assembled modules.
- Cooling devices are also known composed of several exchangers disjoint and connected together by external hoses.
- this type of device has many disadvantages in terms of size, cost of installation and maintenance. Indeed, such external hoses have a limited life and can deteriorate by generating leaks.
- a second object of the invention is to provide a compact cooling device, inexpensive by removing the intermediate parts and robust over time.
- the invention therefore relates to a cooling device of a heat transfer fluid by heat exchange with another fluid having an inlet and at least two outlets arranged at different levels to allow over-cool the heat transfer fluid.
- the device is characterized in that it comprises a modular structure of at least two modules, each module comprising at least one outlet and in that the two modules are hydraulically connected to each other by means of a connector male of a first module cooperating by interlocking with a complementary shaped female end of a second module.
- such a cooling device can be assembled / disassembled into at least two modules without requiring welding operation or connection by a set of external hoses.
- a simple engagement between the male end and the socket makes it possible to hydraulically connect the two modules in series.
- the male and female ends of the two modules can be arranged at the facing faces of the two modules.
- the facing faces of the two modules which may be lower and upper faces are closer to one another.
- the male and female end pieces are invisible and do not constitute an outgrowth to the volume formed by the cooling device.
- the male and female ends of the two modules each have a cylindrical shape.
- the interlocking of the two modules makes it possible to eliminate two degrees of mobility in translation along the plane perpendicular to the interlocking direction, but leaves the possible rotation around the axis of this direction.
- the cooling device may comprise an O-ring at the junction between the male and female ends.
- a seal makes it possible to achieve a seal forming a circular circular contact respectively outside the male end and inside the female end.
- Such an O-ring is generally arranged inside a circular groove formed on the surface of the male end.
- the module comprising a female endpiece may comprise a tube extending coaxially with the female endpiece.
- the cooling device may comprise securing means adapted to subjugate in bonded connection the two modules.
- a securing means may in particular be in the form of clips but also screw, dowel or reversible crimping to separate the two modules if necessary.
- the two modules can be separated by an air gap.
- a thermal bridge is made between the two modules, which gives the device an important resistance to thermal shocks.
- the two modules can expand freely relative to each other without generating additional constraints on the module with which they are assembled.
- the invention relates to a device for cooling a heat transfer fluid.
- such a cooling device (1,11) comprises an inlet (2) connected generally by a hose with a heat source such as a heat engine. It also comprises two outlets (3, 4) arranged at different levels in the device so as to make it possible to draw the coolant at different temperatures depending on the need.
- Such a cooling device (1,11) further comprises a modular structure of at least two modules (5,6) assembled by interlocking to allow a hydraulic connection between the two modules (5,6).
- Each module (5, 6) then has an outlet (3, 4) also connected with a hose for connecting the cooling device with one or more additional devices.
- the hydraulic connection between the two modules (5, 6) is furthermore made by interlocking a spigot (7) positioned on a first module (6) in a socket (8) positioned on a second module (5).
- these male and female ends (7, 8) are arranged on the lower and upper faces of the two modules (5, 6), respectively, so as to position the various inlets (2) and outlets (3, 4) in a same plan.
- the lower face (9) of the first module (6) then faces the upper face (10) of the second module (5) and in this way, the interlocking zone between the two modules (5, 6) is fully integrated in the volume formed by the cooling device (1,11).
- an O-ring (12) can be arranged on the spigot (7) so as to provide a seal at the connection between two modules (5, 6).
- an air gap (16) makes it possible to create a thermal bridge between the two modules (5, 6) and thus to avoid the formation of thermal shocks at the junction between the two modules (5, 6).
- the securing means (14) may be in the form of clips or removable crimping rings cooperating with two flat portions emerging from the lower (9) and upper (10) faces of the two modules ( 5.6).
- the securing means (15) may also be in the form of screws, rivets or the like which also cooperate with two planar portions of the two facing faces (9,10).
- One of the two modules (5) may also comprise a tube (13) extending coaxially with the socket (8) so as to capture the heat transfer fluid inside the module (5) at a predetermined temperature.
