High-water-temperature and large-temperature-difference heat exchange equipment

Abstract

The invention provides high-water-temperature and large-temperature-difference heat exchange equipment which comprises a shell, a draught fan and a heat exchanger, the draught fan and the heat exchanger are arranged in the shell, the shell is provided with an air inlet and an air outlet, the draught fan is configured to suck air into the shell through the air inlet, and the heat exchanger is configured to suck the air into the shell through the air outlet. The heat exchanger comprises at least one heat exchange structure, and each heat exchange structure comprises at least one first inclined section and at least one second inclined section which are connected in series. The at least one first inclined section and the at least one second inclined section are alternately arranged in the flowing direction of the gas in the shell, and the adjacent first inclined section and second inclined section are combined to form a V shape.

Description

technical field [0001] The present application relates to the technical field of air conditioning and refrigeration, in particular to a heat exchange device with high water temperature and large temperature difference. Background technique [0002] With the increasing heat load density of places such as data centers and communication equipment rooms, the energy consumption problem is also becoming more and more serious. Power in a data center is mainly consumed by two types of equipment: IT equipment and computer room equipment. IT equipment mainly includes servers, storage equipment and network equipment; equipment room equipment includes UPS, power distribution equipment, cables, air conditioners, fresh fans, humidifiers, lighting equipment, monitoring equipment, etc. From the current domestic and foreign survey data, in most data centers, the power consumption of equipment room equipment is higher than that of IT equipment, so the design of air conditioning and refrigera...

AI Technical Summary

Problems solved by technology

[0003] The design water temperature difference of the water system in the conventional data center air-conditioning and refrigeration system is 5-6 degrees, so the design of the current chilled water precision air-conditioning system (and row cooling, cold wall, dry cooler, etc.) is designed to ensure that the supply air temperature is 18-27 degrees adjustable, and under the premise of ensuring the temperature difference between the return air, the temperature difference between the inlet and outlet water of the heat exchange coil is 5-6 degrees, and maintaining the temperature difference between the inlet and outlet water will cause high energy consumption and high power consumption of the refrigeration equipment
