Systems and methods for a thermal management control valve with a louver plate assembly

A thermal management control valve for an electric vehicle, the thermal management control valve comprising:

• a first housing;
• a second housing coupled to the first housing at a bonding interface formed between the first housing and the second housing;
• a rotary actuator including a drive shaft defining a drive axis, wherein the drive shaft is offset from the bonding interface so that the bonding interface extends linearly past the drive shaft;
• a cam coupled to the drive shaft and including a cam slot that extends circumferentially around the drive axis, wherein the cam slot extends circumferentially around a majority of the cam;
• and
• a louver plate sealed between the first housing and the second housing and including a pin and a plurality of louver slots extending through the louver plate, wherein the pin extends into the cam slot so that rotation of the cam rotates the cam slot relative to the pin and linearly move the louver plate to selectively allow or inhibit fluid flow through the plurality of louver slots.

• a cam coupled to the drive shaft and including a cam slot that extends circumferentially around the drive axis, wherein the cam slot extends circumferentially around a majority of the cam, wherein the cam slot defines a first portion at a first circumferential position and a second portion at a second circumferential position, and wherein the first portion extends a first radial distance from the drive axis and the second portion extends a second radial distance from the drive axis, the first radial distance being less than the second radial distance;
• and
• a plurality of louver plate assemblies coupled to the cam and arranged between the first housing and the second housing, each of the plurality of louver plate assemblies includes a louver plate with a louver slot and a louver surface defining a surface normal that extends in a direction perpendicular to both the drive axis and a radial direction defined relative to the drive axis,
• wherein the rotary actuator is configured to rotate the cam to a predefined rotary position so that the louver plates move along the radial direction to selectively allow or inhibit fluid flow through the louver slots, and wherein each of the louver surfaces is coplanar.
