Abstract

A fluid heat exchanger (12) for use in a fluid heating system (10) is disclosed that includes a rapidly heatable inside tube (30) surrounded by a hollow outside tube (42) for heating a fluid (18) flowing between the inside tube (30) and the outside tube (42) for circulation through the fluid heating system (10). When the inside tube (30) is rapidly heated, the circulated fluid (18) is rapidly heated to a predetermined temperature for use in the fluid heating system (10).

Description

technical field

[0001] The invention relates to a heat exchanger, especially a fluid heat exchanger. More specifically, the present invention relates to a fluid heat exchanger capable of rapidly heating a fluid flowing between two tubes of the heat exchanger. Background technique

[0002] Typically, fluid heating systems consist of a metallic resistive coil, called a heating element, wound around the outside of a hollow tube. Fluid flows through the tube and is heated by the heating element; however, this arrangement has several disadvantages. Prior art heating systems are not efficient at heating fluids, especially at low fluid flow rates. In addition, such heating systems do not readily form compact shapes and require additional time to heat the fluid to the predetermined temperature used in the fluid heating system.

[0003] An improvement on the prior art is found in US Patent No. 5,590,240 to Rezabek, which discloses a fluid heating system comprising an insulated she...

Embodiment Construction

[0036] Referring to the drawings, a preferred embodiment of the fluid heating system of the present invention is shown in FIG. 4 and generally designated 10 . The fluid heating system 10 includes a housing 13 containing a body 17 defining an elongated upper portion 25 and a lower portion 26 having a fluid heat exchanger 12 disposed therein providing means for heating a fluid 18 to a predetermined temperature. heating equipment. Fluid 18 enters upper section 25 from return side 22 of fluid heating system 10 and is heated while flowing along upper section 25 and lower section 26 . The heated fluid 18 then exits the lower portion 26 and flows into the inlet side 24 and through the remainder of the fluid heating system 10 . Once circulated, the fluid 18 flows through the return side 22 so that the above process is repeated. The temperature level of the fluid 18 is maintained by a temperature control system 20 .
