Serviceable accumulator with integrated plate fin heat exchanger

A thermal management system comprising:

• a refrigerant circuit including, in an order of flow of a refrigerant through the refrigerant circuit, a compressor, a condenser, a high-pressure side of an internal heat exchanger, an expansion element, an evaporator, an accumulator, and a low-pressure side of the internal heat exchanger,
• wherein the high-pressure side of the internal heat exchanger includes first flow passages formed therein and the low-pressure side of the internal heat exchanger includes second flow passages formed therein, wherein the first flow passages are configured to convey a first flow of the refrigerant therethrough and the second flow passages are configured to convey a second flow of the refrigerant therethrough, wherein the first flow of the refrigerant and the second flow of the refrigerant are fluidly distinct from one another within the internal heat exchanger;
• and
• wherein the accumulator includes a can and a cap removably coupled to the can, wherein an interior of the can is configured to convey the second flow of the refrigerant therethrough to separate a liquid portion thereof from a vapor portion thereof and/or to remove moisture therefrom, wherein the internal heat exchanger is coupled to the cap and is removable from the can therewith, wherein removal of the cap and the internal heat exchanger from the can provides access to the interior of the can, wherein the heat exchanger includes a stack of heat exchanger plates with the first flow passages and the second flow passages formed between adjacent ones of the heat exchanger plates, and
• wherein a fluid conduit extends through the first flow passages and the second flow passages of the heat exchanger by penetrating the heat exchanger plates, the fluid conduit configured to convey the second fluid flow to the interior of the can.
