A modular heat exchanger includes: two finned heat sinks, each finned heat sink has multiple guiding plates and a mounting recess; a securing assembly for securing the two finned heat sinks; a heat conduction pipe mounted in the mounting recesses; multiple modular blocks linearly arranged, and each modular block has multiple inlet through holes and multiple outlet through holes; multiple water pipes, each water pipe has two ends mounted through the inlet through holes and the outlet through holes respectively; and multiple coolers mounted to an outer sidewall defined on at least one of the modular blocks. It is convenient to assemble, disassemble or expand the modular heat exchanger, so as to improve performance of the modular heat exchanger. When one of the coolers fails, it is able to reach and detach said failed cooler by disassembling some parts of the modular heat exchanger, which is convenient.

A heat exchanger for fluids includes an elongated conduit. At least two spaced fluid passageways are defined in the conduit and extend longitudinally through the conduit from a first end thereof to a second end thereof. A heat transfer element thermally contacts a surface of the conduit to transfer heat to or from a fluid flowing through the at least two spaced passageways. The conduit can be unitary and of one piece. In one embodiment, the conduit can be a single crystal.

A temperature control device has a temperature acquisition unit that acquires information indicating a temperature around a user and a control unit that controls a Peltier element worn by the user to cool or warm the user based on the temperature. The control unit causes the Peltier element to warm the user when the temperature is higher than or equal to a first threshold and causes the Peltier element to cool the user when the temperature is lower than a second threshold.

In one aspect, 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 sheets, and wherein the chiller/heater component comprises an electron flow through the plurality of parallel sheets to facilitate a thermal heat transfer by a Peltier effect.
