Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 1 As shown, the heat dissipation device according to the present invention includes a heat exchanger 1, and the heat exchanger 1 is provided with an inlet port 11 and an outlet port 12, and in the heat exchanger 1 there is a cooling pipes. The heat dissipation pipe between the two ports can be a straight line passage or a curved passage. Preferably, the heat dissipation passage is spread throughout the entire heat dissipation device. Like this, if an external heat dissipation medium is introduced, the heat dissipation effect of the heat dissipation device can be improved. Fully play, effectively improve the heat dissipation efficiency. The inlet port 11 and the outlet p...

Abstract

The invention provides a heat radiating device, a frequency converter and a frequency-variable air conditioner. The heat radiating device of the invention comprises a heat exchanger (1) and the heat exchanger (1) is provided with an inlet end (11) and an outlet end (12) thereon. A heat radiating pipe is arranged between the inlet end (11) and the outlet end (12) in the heat exchanger (1). The heat radiating device of the invention greatly reduces the volume of a heat radiating plate so as to effectively improve heat radiating efficiency, reduce cost of heat radiation, and improve safety and stability of a frequency converter module. The frequency converter of the invention comprises a circuit control system, wherein the circuit control system is controlled by a mainboard of the frequency converter and comprises an electromagnetic valve (4) connected to the inlet end (11) of the heat radiating device. By using the frequency-variable air conditioner of the invention, the frequency converter module always runs in a rational temperature range, thereby achieving the purpose of protecting stable and reliable operation of the frequency converter.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a cooling device, a frequency converter including the same, and a variable frequency air conditioner. Background technique [0002] The frequency converter module plays a role of power conversion and amplification in the whole frequency converter. Due to the switching loss and the resistance of the module itself, heat will be generated during the working process, and the greater the power of the unit corresponding to the frequency converter, the greater the heat generation. If the heat is not dissipated in time, it will affect the performance of the module or even burn out the module. Therefore, the heat dissipation of the inverter module has always been a key point in the design of the inverter. [0003] At present, the commonly used heat dissipation methods for inverter modules mainly include fan forced convection heat dissipation, heat sink radiation heat dissipation, and heat ...
