[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0029] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0030] See attached Figure 1-3 As shown, an embodiment of the utility model is an efficient and energy-saving cold chain cold storage evaporative condenser, comprising a condensing box body 1, air inlets 101 are provided on both sides of the condensing box body 1, an air outlet 102 is provided on the top of the condensing box body 1, a dehydrator 103 is provided inside the condensing box body 1 and at a position corresponding to the air outlet 102, a heat exchange tube 104 is further provided inside the condensing box body 1, a spraying mechanism 105 capable of spraying in multiple directions is provided on the condensing box body 1 and at a position corresponding to the heat exchange tube 104, and a reflux mechanism 106 is provided on the side of the condensing box body 1 and at a position corresponding to the spraying mechanism 105.

[0031] The two ends of the heat exchange tube 104 are respectively connected to the evaporator in the refrigeration system in the cold chain cold storage. Under the action of the spraying mechanism 105, the reflux mechanism 106 and the dehydrator 103 in this embodiment, the heat exchange tube 104 can efficiently cool the refrigerant flowing out of the evaporator, thereby realizing the circulation flow of the refrigerant and the normal operation of the refrigeration system in the cold chain cold storage.

[0032] The main function of the dehydrator 103 is to remove moisture from the air after it has been processed within the condenser housing 1. Specifically, as the refrigerant in the refrigeration system flows through the heat exchange tubes 104 and dissipates heat, the surrounding water mist (generated by the spray mechanism 105) evaporates and removes heat, thereby helping to cool the refrigerant. During this process, the air carries a large amount of water vapor. The dehydrator 103 is typically located at the top of the condenser housing 1, near the air outlet 102. When the water vapor-laden air passes through the dehydrator, it uses a mechanism (such as condensation, adsorption, or membrane separation) to separate the water vapor from the air, leaving the air exiting the condenser housing relatively dry. This reduces the amount of moisture in the air and prevents water vapor from condensing and dripping onto the bottom of the condenser housing or onto the heat exchange tubes during the condensation process, thereby improving condensation efficiency and heat exchange.

[0033] The condensed air still contains a large amount of moisture, which will condense into ice in the subsequent refrigeration system or pipeline, causing equipment failure or performance degradation. The dehydrator can reduce this risk.

[0034] By recycling and reusing the water generated by the spraying mechanism, dependence on external water sources is reduced, while wastewater discharge is reduced, which is beneficial to energy conservation and environmental protection.

[0035] The dehydrator plays an important role in improving condensation efficiency, protecting subsequent equipment and saving energy and protecting the environment in the evaporative condenser.

[0036] See attached Figure 3As shown, the spraying mechanism 105 includes a rotating spraying assembly 1051, a driving assembly 1052 for driving the rotating spraying assembly 1051 is provided on the top of the rotating spraying assembly 1051, and a limiting assembly 1053 is installed inside the condensation box 1 and at a position corresponding to the rotating spraying assembly 1051.

[0037] The rotary spray assembly 1051 includes a spray pipe 10511 , at the bottom of which are provided a plurality of spray heads 10512 arranged at equal distances. A water inlet pipe 10513 is installed at one end of the spray pipe 10511 , and a connecting hose 10514 is installed at the other end of the spray pipe 10511 .

[0038] The driving assembly 1052 includes a driving shaft 10521 fixedly connected to the top of the spray pipe 10511, a driven wheel 10522 fixedly connected to the top of the driving shaft 10521, a forward and reverse motor 10523 fixedly connected to the side of the condensation box 1, a driving wheel 10524 fixedly connected to the output shaft of the forward and reverse motor 10523, and the driving wheel 10524 is connected to the driven wheel 10522 through a transmission belt 10525.

[0039] The limiting assembly 1053 includes a limiting bearing seat 10531 rotatably mounted on the driving shaft 10521 , and both sides of the limiting bearing seat 10531 are fixedly connected to the limiting rod 10532 , and the side of the limiting rod 10532 close to the inner wall of the condensation box 1 is fixedly connected to the inner wall of the condensation box 1 .

[0040] The reflux mechanism 106 includes a receiving groove 1061 arranged at the bottom of the inner wall of the condensation box 1, and a reflux pump 1062 is installed on the side of the receiving groove 1061. The top of the reflux pump 1062 is connected to the connecting hose 10514 through the reflux pipe 1063.

[0041] In order to prevent impurities in the air from entering through the air inlet 101 , in the embodiment of the present invention, a dustproof net 1011 for gas filtering is installed on the inner wall of the air inlet 101 .

[0042] To sum up, the embodiment of the utility model drives the driving wheel 10524 to rotate through the forward and reverse motor 10523, and drives the driving shaft 10521 at the bottom of the driven wheel 10522 to rotate under the transmission action of the transmission belt 10525, thereby driving the spray pipe 10511 to move back and forth continuously, increasing the uniformity of the water mist spraying. At the same time, by setting the receiving groove 1061, the sprayed water mist can be collected in a centralized manner, and the return pipe 1063 transmits it to the spray pipe 10511 to reuse water resources and reduce energy consumption.
