されるものである。BACKGROUND TECHNOLOGY Conventionally, a heat exchanger is attached to an electronic device or an electrical device, such as a CRT display device, which itself generates heat, in order to dissipate the heat. Conventional heat exchangers used in the conventional heat exchanger are shown in FIGS. 1 to 3. That is, in the one shown in FIG. 1, fans F and F' are provided on the outside of both ends of the corrugated fin 1, and
In addition, as shown in the sectional view taken along line A-A in FIG.
All but 3 are closed by side plates 4 and 5. The air outlet ports 2 and 3 are provided on opposite sides of both ends of the corrugated fin 1, and both end surfaces 6 and 7 of the corrugated fin 1 are formed in the waveform shape of the side plates 4 and 5 and the corrugated fin 1. The partitions formed by the walls are closed alternately. Therefore, air a sent in by fan F
As shown in FIG. 2, the side plate 4 and the corrugated fin 1 are
The air flows out of the heat exchanger through the space formed by the air outlet 2. Further, the air b sent by the fan F' passes through the space formed by the side plate 5 and the corrugated fins 1, and is discharged to the outside of the heat exchanger through the air outlet 3. As a result, while the air a and b' flow through the corrugated fin 1, heat is exchanged between the air a and b via the corrugated fin 1, and the hot air is cooled and heat is radiated.

This heat exchanger differs from the heat exchanger shown in FIG. 1 in that F' is provided on both end sides of the corrugated fins 1, but its function is almost the same as that shown in FIG.

つた。Problems to be Solved by the Invention In the conventional heat exchanger described above, in the heat exchanger of the type shown in FIG.
Since the heat exchanger is provided so as to protrude outside both ends thereof, even though the thickness of the heat exchanger can be reduced, its length becomes longer by the amount of fans F and F'. In addition, the heat exchanger of the type shown in Fig. 3 has fans F and F' on the side of fin 1, so the length can be made smaller, but the thickness is thicker, making the heat exchanger compact. It's difficult. Furthermore, if the air reservoirs 8 and 9 provided between the fans F and F' and the fin 1 are made smaller, the horsepower of the fan must be increased and air must be sent under greater pressure, so an air reservoir of a certain size must be provided. As a result, the heat exchanger could not be formed compactly. Furthermore, as shown in FIG. 2, heat exchange in the conventional heat exchanger is not performed over the entire surface of the corrugated fin 1, but is performed only at portions c of the fin side surfaces of the air passages a and b. This was not performed on the surfaces in contact with the side plates 4 and 5, and the area of the fins for heat exchange was small, resulting in poor efficiency.
そこで、本発明の目的は、上記従来の熱交換器
の欠点を改良し、コンパクトで効率のよい熱交換
器を提供することにある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the above-mentioned drawbacks of the conventional heat exchanger and to provide a compact and efficient heat exchanger.

A blower fan is disposed on the side where the fins are far apart and an air inlet is bored in the outer wall, while an air outlet is bored in the other end of the outer wall where the corrugated fins and the outer wall are close to each other. It has a configuration that

What is different from the conventional example shown in Fig. 3 is the corrugated fin 1.
1 is a pair of opposing machine frame outer walls 14, 1 of the heat exchanger
This point is that it is installed at an angle with respect to 5.

穿設されている。 Then, air is formed as an air reservoir on the side where the corrugated fin 11 and the outer walls 14, 15 are largely separated, and the blowing fans F, F' are disposed on the side where the outer walls 14, 15 are located. are provided with an air inlet, while air outlet ports 12, 13 are provided at the other ends of the outer walls 14, 15 adjacent to the corrugated fins 11.

うに、交互に開放しておけばよいことになる。 Further, the side plates of the corrugated fins 11 are not fixed as shown in FIG.
The passage b is formed by a space within the machine frame 17 divided by the corrugated fins 11. Note that the end surfaces 16 and 18 of the corrugated fins 11 may be completely closed, but only the surface on the side forming the air passage may be opened. That is, as explained in the conventional example shown in FIG. 1, it is sufficient to open the gates alternately.

Air b flows along one surface of the corrugated fin 11, flows out from the air outlet 12, and air b sent in by the fan F' flows through the other space along the other surface of the corrugated fin 11, and exits from the air outlet 13. leak.

The air is taken in again from the intake inlet and heat exchanges with the outside air flowing through the other air passage through the entire surface of the corrugated fins 11 having a large surface area.

ことができる。Effects of the Invention The heat exchanger of the present invention divides the space inside the machine frame by tilting and fixing the corrugated fins to a pair of opposing outer walls of the machine frame. Since the large space formed between the end portion and each of the outer walls is used as an air reservoir and a blower fan is installed, the heat exchanger can be made compact, while the air reservoir is large to reduce air resistance. It is possible to reduce the power consumption of the fan. Furthermore, since no side plates are fixed to the side surfaces of the fins, the entire surface of the wavy fins having a large surface area comes into contact with air, allowing efficient heat exchange.

埃等によつて故障が生じることもない。 Furthermore, since the air passages divided by the corrugated fins are formed so as to gradually become narrower toward the air outlet, the outflow air velocity from the air outlet increases, making it difficult to install the heat exchanger. This improves convection inside the device and enhances the heat dissipation effect.Moreover, since outside air does not enter the air circulating inside the device, malfunctions do not occur due to moisture, dust, etc.
