Heat exchange device and its solenoid valve

Abstract

The invention discloses an electromagnetic valve, which comprises a valve seat (1) provided with a valve port (11), wherein the valve seat (1) is connected with a first connecting pipe (21); the valve seat (1) is also connected with a sleeve (3); a coil (4) is fixed on the external part of the sleeve (3); a valve core component (5) is arranged in the sleeve (3) and used for opening or closing the valve port (11); the one end of the sleeve (3) far from the valve seat (1) is coaxially communicated with a second connecting pipe (22); and the valve core component (5) is provided with a cooling medium passage which is communicated with the valve port (11) when the valve port (11) is opened, and the cooling medium passage is communicated with the second connecting pipe (22). The mounting space of the electromagnetic valve in a heat exchange device can be reduced, so the mounting space of a heat exchanger is increased, and then the efficiency of the heat exchange device is improved. Besides, the invention also discloses the heat exchange device comprising the electromagnetic valve.

Description

technical field [0001] The invention relates to the field of fluid control components, in particular to an electromagnetic valve. In addition, the present invention also relates to a heat exchange device comprising the solenoid valve. Background technique [0002] In the field of refrigeration technology, the solenoid valve is the refrigerant flow control part of the refrigeration equipment. Its working process is generally: as the coil is energized or de-energized, the solenoid valve is opened or closed in the refrigeration equipment system such as air conditioners, thereby controlling the circulation and flow of the refrigerant. interruption. Of course, the scope of application of the solenoid valve is not limited to the above-mentioned refrigeration technology field, for example, it is also widely used in the hydraulic field. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical solenoid valve in the prior art. [0004] figur...

AI Technical Summary

Problems solved by technology

[0005] like figure 1 As shown, in order to facilitate welding, the second connecting pipe 2'2 installed in the radial direction of the valve seat 1' needs to have sufficient length, but the radial connecting pipe with sufficient length will cause the entire electromagnetic valve to occupy a relatively large area in the air conditioner indoor unit. Large installation space, under the premise that the total installation space of the air conditioner indoor unit is certain, the installation space occupied by the heat exchanger will be reduced, and the volume of the installed heat exchanger will be reduced, thus reducing the energy efficiency of the air conditioner indoor unit
