ニウム製押出品のし）のは。Conventional heat exchangers of this type include those made by brazing copper pipes a and b together, as shown in Figure 1, or aluminum extrusions d, as shown in Figure 2. ing. However, the former, that is, copper vibrators a and b with solder joints, is heavy and requires a lot of effort to assemble as it is necessary to fix pipes a and b to each other with solder joints C. It is expensive, and has disadvantages such as insufficient heat exchange due to the small contact area between the pipes.Furthermore, in order to increase thermal efficiency, it was necessary to flatten the vibrator a, 1). Also, the latter is an extruded aluminum product.

器の改良が望まれている。Therefore, as a means to solve the above problem, a heat exchanger in which a copper pipe is installed in a hole formed in an extruded aluminum shape is considered, but in this type of heat exchanger, it takes time and time to insert the pipe. It is time-consuming, and it takes time and effort such as expanding the pipe to firmly fix the pipe and the extruded aluminum profile. Moreover, if the length of the copper pipe is less than 2J, there will be problems such as difficulty in pipe installation and noise.In the end, the above problems have not been solved, and at present, the above problems cannot be solved. Improvements in heat exchangers are desired.
