Description

Technical Field

[0001] This utility model relates to the field of heat dissipation system technology, specifically an energy-saving heat dissipation system. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers. For example, low-temperature polytetrafluoroethylene (PTFE) heat exchangers for power plants are a new type of device used in power plants to recover waste heat by reducing flue gas temperature.

[0003] The invention patent with publication number CN110268216BB discloses a heat exchange plate and a heat exchanger. The plate, used in the heat exchanger between a first medium and a second medium, has an extending main plane and a main longitudinal direction (L), and includes: a first heat transfer surface parallel to the main plane and in contact with the first medium; and a second heat transfer surface parallel to the main plane and in contact with the second medium. The first surface includes a first medium inlet region, a first medium transfer region, and a first medium outlet region, the first medium outlet region including a first medium outlet port. The second surface includes a second medium inlet region, a second medium transfer region, and a second medium outlet region, the second medium inlet region overlapping the first medium outlet region and including a second medium inlet port that does not overlap with the first medium outlet port. A key feature of this invention is that the first medium outlet region includes a protruding ridge extending from a corresponding edge of the first surface perpendicular to the longitudinal direction, wherein the protruding ridge forms a barrier system for the first medium and defines a channel along which the first medium is forced to travel. This channel initially extends toward the second medium inlet port, then around the second medium inlet port, and subsequently extends away from the second medium inlet port.

[0004] The cooling water coming out of the workshop is at a relatively high temperature, and it exchanges heat with the water in the water tower. When the outdoor temperature is low, it can use the outdoor temperature to cool down. However, when the outdoor temperature is high, the heat dissipation effect is poor, which makes it difficult for the cooling water to cool down. The heat exchange efficiency is low, which increases the energy consumption of the equipment. In order to solve the above problems, this application proposes an energy-saving heat dissipation system.

This system utilizes tap water and a heat exchange plate to exchange heat with the coolant. During the transportation of tap water and coolant, heat exchange fins are used for heat exchange, thereby increasing the exchange time between the coolant and tap water and improving the cooling effect on the coolant. Simultaneously, the waste heat of the cooling water is used to heat the tap water, reducing the electrical energy loss for heating the tap water, thus solving the problems mentioned in the background art.

Heat exchange fins are arranged around the outer wall surface of the inner heat exchange tube. The heat exchange fins are distributed at equal intervals, and adjacent groups of heat exchange fins are arranged in an alternating manner.

[0010] Preferably, each of the heat exchange fins has a water guide hole through it, which allows cold water to pass quickly through the cold water flow chamber.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] This invention utilizes tap water and a heat exchange plate to exchange heat with coolant, thereby improving the cooling effect of the coolant. The heat exchange connecting pipe has an inner heat exchange pipe and an outer heat exchange pipe in the middle. Coolant flows in the inner heat exchange pipe, while tap water flows in the cold water flow chamber.
