Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to a fin evaporator with high-efficiency heat dissipation. Background Art

[0002] Evaporation is the physical process of liquid to gas. Generally speaking, an evaporator is an object that converts liquid into gas. There are a large number of evaporators in industry, and the evaporator used in refrigeration systems is one of them. The evaporator is a very important part of the four major refrigeration parts. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, gasify and absorb heat to achieve the refrigeration effect. The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize. The evaporation chamber completely separates the gas and liquid phases.

[0039] Specifically, an evaporator assembly 4 is symmetrically arranged in the housing 1, and a linkage assembly 3 is movably connected to the top of the evaporator assembly 4. The linkage assembly 3 is driven by the driving assembly 2 to reciprocate up and down, and the linkage assembly 3 drives the movably connected evaporator assembly 4 to expand along the directional assembly 6 to both ends in an inverted V structure. The expanded evaporator assembly 4 increases the contact area with the gas, and the guide assembly 5 arranged at one end of the evaporator assembly 4 is opened. The heat exchange efficiency of the evaporator assembly 4 is improved by increasing the flow rate of the gas in the housing 1. When the gas flow rate in the housing 1 decreases, the linkage assembly 3 is driven by the driving assembly 2 to drive the evaporator assembly 4 to close and dock with the exhaust port 12 at the top of the housing 1.

[0050] Working principle: the evaporator assembly 4 is symmetrically arranged in the box 1, and the linkage assembly 3 is movably connected to the top of the evaporator assembly 4.

The expanded evaporator assembly 4 increases the contact area with the gas. The guide assembly 5 set at one end of the evaporator assembly 4 is opened, and the heat exchange efficiency of the evaporator assembly 4 is improved by increasing the flow rate of the gas in the box 1. When the gas flow rate in the box 1 is reduced, the linkage assembly 3 is driven by the driving assembly 2 to expand. The driving assembly 3 drives the evaporator assembly 4 to close and dock with the exhaust port 12 at the top of the box body 1. The guide assembly 5 set at one end of the evaporator assembly 4 is closed to form a channel, so that the evaporator assembly 4 can work under low energy consumption.

The linkage assembly 3 reciprocates between the two evaporator assemblies 4 and the guide assembly 6, so that the linkage rod 33 in the linkage assembly 3 drives the two symmetrically arranged evaporator assemblies 4 to move in an inverted V structure along the directional assembly 6. Secondly, the support bar 51 in the guide assembly 5 is movably connected to the linkage rod 33 and the rotating shaft rod 44 through the collar pieces 52 fixedly connected at both ends. When the linkage assembly 3 drives the evaporator assembly 4 to unfold toward both ends along the directional assembly 6, the movable bar 54 connected to the guide plate 53 through the rotating rod 510 is opened under the action of the support spring 59, and the support spring 59 is respectively fixed to the movable bar 54 through the positioning rod 57. On the support bar 51, when the linkage component 3 drives the evaporator component 4 to contract, the movable wheel 55 movably connected to one end of the movable bar 54 moves along the directional component 6, and the movable wheel 55 drives the guide plate 53 to fit with the support bar 51 through the movable bar 54, so that the guide plate 53 is closed to form a guide channel, so that the guide component 5 can move synchronously with the movement of the evaporator component 4, so that the device can control the heat exchange efficiency of the evaporator component 4 according to the flow rate of the gas in the box body 1, thereby avoiding the energy loss caused by the evaporator component 4 not being able to control the heat exchange efficiency according to the gas flow rate.
