Problems solved by technology

[0002] The existing radiator adopts the positive pressure water injection method, and it is difficult to fill the capillary tube in the inner cavity of the radiator with water. Generally speaking, if the positive pressure water injection method is used for water injection, there will be 20-30% air content, and the capillary tube in the inner cavity of the radiator Higher air content results in poorer thermal performance

Embodiment Construction

[0026] refer to figure 1 , the present invention is implemented like this:

[0027] The invention discloses a vacuum water injection method for a radiator, which comprises two processes of vacuumizing the capillary of the radiator and injecting water into the capillary. Specific methods include:

[0028] 1) Appearance inspection, conduct appearance inspection on the capillary tube of the radiator, and select the radiator with damaged appearance;

[0029] 2) Load the workpiece, and load the radiator with qualified appearance to the working position;

[0030] 3) The workpiece is vacuumed, and the capillary tube of the radiator is vacuumed by a vacuum device, so that the vacuum degree of the inner cavity reaches below 3000Pa, and the imported vacuum pump is used to vacuum the radiator, the highest vacuum degree: 1000~3600Pa. The sealing of its water injection port is especially important;

[0031] 4) Vacuum pressure maintenance. After vacuuming, carry out pressure maintenance...

Abstract

The invention relates to a water injection method for a radiator, in particular to a vacuum water injection method for the radiator. The method comprises the following two procedures: the capillary pipes of the radiator are vacuumized, and water is injected into the capillary pipes. The invention has the advantages that a negative pressure water injection way is adopted, i.e. the capillary pipes of the radiator, ;which are needed to be injected with water, are vacuumized, and enough vacuum degree which can reach up to lower than 10Pa is ensured, thereby the air content in the capillary pipes of the radiator is only about 0.25 percent, the water can be injected into the capillary pipes to the largest extend, and the radiating efficiency is increased by 30-50 percent.

Description

technical field [0001] The invention relates to a water injection method for a radiator, in particular to a vacuum water injection method for a radiator. Background technique [0002] The existing radiator adopts the positive pressure water injection method, and it is difficult to fill the capillary tube in the inner cavity of the radiator with water. Generally speaking, if the positive pressure water injection method is used for water injection, there will be 20-30% air content, and the capillary tube in the inner cavity of the radiator Higher air content results in poorer thermal performance. [0003] Based on the deficiencies of the above radiator water injection method, the inventor designed the "radiator vacuum water injection method" of the present invention. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a vacuum negative pressure water injection method for radiators with a water injection purity of abou...
