A small-sized fluid heating/cooling apparatus for heating or cooling a large amount of gas or liquid at a low cost. Structures where a flow passage for a fluid is formed in a heated or cooled base formed in a plate shape or a column shape, and a fluid which has passed through the narrowed flow passage impinges on a wall of a side face of the base vertically to perform heat exchange are connected in series. Heat exchange is instantaneously performed in a small space and manufacture of a mechanism performing such an operation is easy. A material constituting the flow passage may be a metal or ceramics, and a small-sized fluid heat exchanging apparatus can be manufactured at a low cost.

Fluid heat exchanging apparatus

In a small-sized fluid heat exchanging apparatus that heats or cools a huge amount of gas or liquid, a structure makes fluid having a high flow speed impinge perpendicularly against a wall. A flow passage is divided into a high-speed flow passage and a low-speed flow passage, and the high-speed flow passage and the low-speed flow passage are arranged so as to intersect perpendicularly with each other, according to guidelines for the shape of the flow passage. A flow passage designed according to the guidelines provides highly-efficient heat exchange.

A solid gasification apparatus includes a reaction chamber thermally insulated by a heat insulating material, a heat beam fluid heat exchange apparatus that produces a first heated gas and a second heated gas, and a unit that includes a gas flow path. The unit sprays the first heated gas against a material solid in a reaction chamber to heat the material solid, and, simultaneously, makes the material solid react with the first heated gas to produce a produced gas containing the element of the material solid. The unit makes a second heated gas contact and react with the produced gas.

Such etching of a thin film avoids causing damage to the resist mask used.
