Heat exchanger tubing assembly and conductive casing

A heat exchanger tubing assembly (200) for insertion into a channel (120) in a conductive casing (110) having a first piece (114) and a second piece (118), so that thermal treatment applied to the conductive casing may be transferred through the heat exchanger tubing assembly to a liquid passing through the heat exchanger tubing assembly to create a heat-treated liquid, the heat exchanger tubing assembly comprising:

• a set of at least two conductive segments (240) comprising a first conductive segment (242) and a second conductive segment;
• each conductive segment made of a first material of first thermal conductivity value, each conductive segment short enough to fit into the channel in the conductive casing so that neither a first end portion (244) nor a second end portion (244) of the conductive segment extends out of the conductive casing;
• both the first end portion and the second end portion of each conductive segment (240) having a barbed portion (252) and a flange (248) that extends radially outward from the conductive segment;
• each conductive segment having a longitudinal bore (256) to allow liquid to pass through the conductive segment;
• a first connector tube (212) with a flexible tube (218) connected to the first end portion of the first conductive segment (242) to allow liquid to enter a proximal end (192) of the first connector tube (212) outside of the conductive casing and travel through a longitudinal channel (222) then out a distal end of the first connector tube into the longitudinal bore (256) of the first conductive segment (242);
• the flexible tube (218) made of a second material with a second thermal conductivity value which is lower than the first thermal conductivity value;
• a first curved connector (272) with an interior channel (278), the first curved connector made of a third material with a third thermal conductivity value which is lower than the first thermal conductivity value;
• the first curved connector connecting the second end portion of the first conductive segment and a first end portion of the second conductive segment (442);
• a second connector tube (210) with flexible tube (218), connected to a distal end of a final conductive segment to allow liquid to enter a proximal end of the second connector tube inside of the conductive casing and travel out a distal end of the second connector tube outside of the conductive casing into a subsequent flow path for the heat-treated liquid;
• and
• wherein the set of flanges extending radially outward may be used to engage with flange receiving voids in the conductive casing to help position the heat exchanger tubing assembly within the conductive casing.
