Problems solved by technology
[0007] The invention discloses a heat exchanger and a water-cooling unit, which solves the problem that when the heat exchange tubes of an evaporative condenser are arranged for heat exchange, the refrigerant will gradually liquefy as the temperature decreases, and a liquid film is formed on the inner wall of the horizontal heat exchange tube. Thereby increasing the heat conduction resistance and affecting the heat transfer performance

Embodiment Construction
[0022] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.
[0023] Such as figure 1 and figure 2 As shown, the present invention discloses a heat exchanger, which includes a first heat exchange group 10, a main pipe 20 and a separator 30. The number of heat groups 10 is at least two, and the first heat exchange group 10 includes a first heat exchange tube 11; , the other main pipe 20 communicates with the second end of the first heat exchange tube 11; the partition plate 30 is arranged in the main pipe 20, and the partition plate 30 divides the main pipe 20 into a plurality of communication chambers 21, and the adjacent two second A heat exchange group 10 is connected in series through the communication cavity 21 ; a flow guide structure 31 for passing liquid refrigerant is arranged on the separator 30 . In the heat exchanger of the present invention, a partition plate 30 is arranged i...

The invention discloses a heat exchanger and a water cooling unit. The heat exchanger comprises at least two first heat exchange groups, at least two mother tubes and partition plates. The first heatexchange groups are parts for circulating gas and liquid refrigerants in the heat exchanger, and each first heat exchange group comprises a first heat exchange tube; one mother tube communicates withthe first ends of the first heat exchange tubes, and the other mother tube communicates with the second ends of the first heat exchange tubes; and the partition plates are arranged in the mother tubesand divide the mother tubes into a plurality of communicating cavities, and every two adjacent first heat exchange groups communicate in series through the corresponding communicating cavity. A flowguide structure for allowing a liquid refrigerant to pass through is arranged on each partition plate. According to the heat exchanger, the partition plates are arranged in the mother tubes, and the flow guide structures are arranged on the partition plates, so that gas-liquid separation is realized, a liquid film is prevented from being formed, heat conduction resistance is reduced, and the heatexchange performance is greatly improved.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger and a water cooling unit. Background technique [0002] The main working principle of the evaporative condenser is to condense the refrigerant vapor in the heat exchange tube through the latent heat generated by the evaporation of cooling water sprayed outside the heat exchange tube. It combines the cooling and heat exchange process of the water cooling of the traditional water cooling unit and the cooling and heat exchange process of the air cooling cooling tower, which saves the heat exchange equipment in the intermediate process and reduces the initial investment of the equipment; it has high heat transfer efficiency, compact structure and small volume , less circulating water, and are increasingly widely used in power, chemical, food, petrochemical, refrigeration and other industries. The evaporative condenser is mainly composed of three parts: heat ...
