Thermo-electric chiller/heater component methods and systems

A chiller/heater component of a thermo-electric cooler pump system comprising:

• wherein the chiller/heater component comprises:
• a wetted side of the chiller/heater component comprising a regularly-spaced plurality of parallel rows of elongated elements between which the liquid flows, wherein the plurality of rows of elongated elements are oriented perpendicular to both the flow of the liquid and the wetted side of the chiller/heater component, wherein the plurality of rows of elongated elements extends into the liquid from a single surface of the wetted side of the chiller/heater component, and wherein the wetted side of the chiller/heater component is in contact with the liquid, and
• a dry side of the chiller/heater component comprising a plurality of parallel plates, and wherein the plurality of parallel plates is orthogonal in orientation to the plurality of rows of elongated elements and parallel to the flow of the liquid, wherein there is a seal around the chiller/heater component so that liquid does not escape in a vicinity of the chiller/heater component, and wherein the chiller/heater component comprises an electron flow to facilitate a thermal heat transfer by means of the Peltier effect,
• wherein the plurality of rows of elongated elements comprises a plurality of pins, wherein the plurality of pins comprises a plurality of copper pins,
• wherein each pin of the plurality of copper pins is ten millimeters (10 mm) long,
• wherein a copper sheet is coupled with a Hexagonal Boron Nitride (HBN) sheet, and
• wherein the HBN sheet is underneath the copper sheet.
