Description
Technical Field
The invention relates to the field of cooling systems, in particular to a local adjustment heat exchange unit for a large-scale cooling system.
Background
In some production fields such as chemical industry, there will be large-scale production lines, and there will be a great deal of equipment that need to cool off in a large-scale production line, therefore must adopt supporting large-scale cooling system, and this kind of large-scale cooling system includes the main cooling equipment who is used for providing the coolant liquid, is used for providing the main pressure equipment of power for the flow of coolant liquid, is the hydraulic pump commonly used, and the specification of main cooling equipment and main pressure equipment is great usually to satisfy cooling system can carry out the refrigerated needs for a great deal of equipment in the production line. In such a large-scale production line, since the number of devices to be cooled is large and the types of devices to be cooled are generally various, there are problems that it is difficult to match a part of the devices to be cooled with the cooling liquid of the cooling system, and the pressure of the cooling liquid is generally too low and the temperature of the cooling liquid is too low.
The main reason for this mismatch problem is that the temperature of the coolant provided by the main cooling equipment of the large cooling system, and the pressure of the coolant provided by the main pressure equipment, must first meet the requirements of most of the equipment to be cooled in the production line; when the temperature of the cooling liquid required by a certain cooled device in the local production line is not matched, if the temperature of the cooling liquid required by the cooled device is lower, the special cooling liquid must be provided for the cooled device separately, and the cooling liquid of the cooling system cannot be shared; if the temperature of the cooling liquid required by the cooled equipment is high, the special cooling liquid is provided for the cooled equipment separately, which causes obvious waste and is not compensated, but if the cooling liquid of the cooling system is directly used, the temperature is too low, which makes the requirement difficult to meet; similarly, when the pressure of the cooling liquid needed by a certain cooled device in the local production line is not matched, if the pressure is too high, the pressure is reduced, and if the pressure is too low, in order to meet the pressure requirement of most cooled devices in the production line, the pressure of the cooling liquid provided by the main pressure device in the cooling system cannot be increased directly, but if the pressure of the cooling liquid directly using the cooling system is insufficient, the requirement cannot be met.
Especially for some small-size by cooling equipment that are located large-scale cooling system end, because by cooling equipment's specification less, the cooling requirement is lower, by cooling equipment be located cooling system end simultaneously, it is far away from main pressure equipment, consequently very easy the coolant temperature that appears large-scale cooling system simultaneously and is low, and the coolant pressure is not enough two-sided problem, the condensation phenomenon takes place easily on the surface by cooling equipment when the temperature is too low, the comdenstion water lasts and drips and can cause ponding at the production site, and the speed that the coolant liquid flowed in by cooling equipment is too slow when the pressure is not enough, heat transfer effect is not enough, can not fully cool down.
Disclosure of Invention

The water tank is also connected with a water tank water supply pipe and a water tank blow-off pipe, water is added into the water tank through the water tank water supply pipe, and the water tank blow-off pipe is positioned below the water tank water supply pipe so as to discharge sewage in the water tank.
Two water pumps are installed on the base, the water outlet pipe of the water tank is connected with the water inlet pipes of the two water pumps through a tee joint, and the hot side inlet of the heat exchanger is connected with the water outlet pipes of the two water pumps through another tee joint.
According to the technical scheme, the invention has the beneficial effects that:
the local adjustment heat exchange unit for the large cooling system can ensure that the water in the water tank exchanges heat with the cooling liquid of the cooling system in the heat exchanger and the cooling water after heat exchange can flow into the cooled equipment from the heat exchanger, so that the temperature of the cooling water flowing into the cooled equipment is higher than the temperature of the cooling liquid of the cooling system, and the problem that the temperature of the cooling liquid of the cooling system is too low can be solved; meanwhile, the flowing pressure of the cooling water comes from the water pump of the heat exchange unit, the pressure of the cooling water flowing into the cooled equipment can be accurately controlled by adjusting the pressure of the water pump, and the problem that the pressure of the cooling water is not matched with the cooled equipment can be avoided even if the pressure of the cooling water of the cooling system is low; after cooling the cooled equipment, the cooling water flows back to the water tank through the water tank return pipe, so that the cyclic utilization of the cooling water is realized. The whole simple structure of heat transfer unit, cost are also extremely low, but can solve in the cooling system local cooling system directly by the cooling apparatus and the unmatched problem of cooling liquid temperature and pressure that cooling system did not provide very effectively, are particularly useful for being located the terminal small-size by the cooling apparatus of large-scale cooling system, convenient to popularize and apply.
