トロール装置を付加することは実施困難である。In the case of using the above-mentioned conventional cooling plate to cool equipment having different heat values,
If the temperature of the plate is set to a temperature suitable for one device, it will not be a temperature suitable for the other device. If the temperature is set to a temperature suitable for a device generating a large amount of heat, the device generating a small amount of heat will be excessively cooled. If the temperature is set to a temperature suitable for a device generating a small amount of heat, the device generating a large amount of heat will be insufficiently cooled. Due to the mismatch of the cooling temperature, it may not function in a precision instrument or may malfunction. In particular, when the apparatus is used in a small space such as a space laboratory and it is not desired to increase the weight of the apparatus, it is difficult to prepare a cooling plate dedicated to each apparatus and add a temperature control apparatus to each apparatus.

に格差を設けることができる。In the cooling plate (FIG. 1), the same amount of cooling water as the inlet flow rate flows in the flow path from the inlet port 2 to the branch plate 6. After the branch plate 6, the cooling water is divided into a conventional meandering flow path and a bypass flow path 7. Assuming that the flow distribution ratio of the branch plate is 1: 1, cooling water flows at half the inlet flow in the meandering flow path after the branch plate and at half the inlet flow in the bypass passage. Since the bypass passage is short and the cooling water flowing therethrough is discharged from the outlet port 3 without substantially contributing to the cooling operation, the flow rate of the cooling water for cooling the area B after the branch plate is reduced by half. Become. If the heat radiating area of the area A and the area B are the same and the structure other than the bypass line is the same, the cooling capacity of the latter half area B of the cooling plate is の of the cooling capacity of the first half area A, and is halved. As a result, it is possible to divide a region in one cooling plate and provide a difference in cooling capacity.

Although the flow rate distribution in the branch plate is set to one-to-one, the ratio of the cooling capacity can be arbitrarily set in general by setting an arbitrary heat radiation area ratio and a flow distribution ratio.
Although the cooling area is divided into two in the above-described example, a plurality of cooling areas can be generally divided into three or more depending on the equipment to be installed. This makes it possible to perform cooling according to the number and type of devices requiring cooling.
