Heat exchanger and heat exchange structure of outdoor equipment internal device

Abstract

The invention discloses a heat exchanger and a heat exchange structure of an outdoor equipment internal device. The heat exchanger comprises a shell, a heat dissipation fan and a heat pipe; the lowerpart of the heat pipe is located in the shell, the heat dissipation fan is installed at one end of the heat pipe and located in the shell, and the other end of the shell is provided with a shell air inlet. According to the heat exchanger, the heat pipe is divided into the upper portion and the lower portion, the upper portion is communicated with the outside and used for heat dissipation, the lower portion transmits heat through the shell air inlet, the heat enters the lower portion of the heat pipe in the shell from the shell ventilation opening and flows out through the lower portion of theheat pipe, so as to avoid the situation that the cold air enters the heat exchanger to bring dust into the outdoor equipment to be cooled, so that other devices in the inverter are completely isolatedfrom the external environment to achieve the dustproof purpose; meanwhile, the heat dissipation requirements of the other devices in the inverter are also met.

Description

technical field [0001] The invention belongs to the technical field of outdoor inverter heat exchange, and in particular relates to a heat exchanger and a heat exchange structure of internal components of outdoor equipment. Background technique [0002] With the continuous reduction of the price of centralized inverters, the container inverter solution is gradually eliminated by the market due to its high cost price. In order to improve the profit margin of centralized inverters, various inverter manufacturers have launched outdoor dedicated photovoltaic inverters. With many advantages such as convenient installation, it has gradually occupied a dominant position in the market. Taking the current mainstream centralized 3.125MW inverter in the market as an example, various manufacturers have launched corresponding centralized outdoor photovoltaic inverters. [0003] Since the outdoor inverter is placed directly in the external environment, its internal components are more se...

AI Technical Summary

Problems solved by technology

[0004] (1) The heat of the rest of the components inside the inverter is discharged to the outside of the inverter by means of direct blowing by the fan; although this method can meet the heat dissipation requirements of the rest of the components inside the inverter, the heat dissipation fan will also dissipate the dust Bringing it into the inverter will affect the operation of the inverter. This solution is not recommended for outdoor inverters

[0005] (2) Add a heat exchanger in the cabinet to discharge the heat generated by the rest of the components inside the cabinet to the outside of the inverter through heat exchange. This method can meet the needs of heat dissipation and dust prevention. In the inverter, the protection level of the heat exchange fan is only IP4X, which cannot reach the IP6X protection level required by the outdoor inverter, so the heat exchange fan will be damaged.
