As shown in fig. 1 to 2, a device for prompting replacement of a zinc bar according to a preferred embodiment of the present invention is applied to a heat exchanger 1, wherein the heat exchanger 1 has a housing 12, and a cooling medium 13 is provided in the housing 12. The device capable of prompting the replacement of the zinc bar comprises: a plug screw 2, a zinc rod 3 and a discriminator. The screw plug 2 is screwed into the shell 12 of the heat exchanger 1, and a through hole is formed at the head of the screw plug 2. The zinc rod 3 is fixedly connected with the tail part of the screw plug 2, the zinc rod 3 is positioned in the shell 12, and one end of the zinc rod 3 close to the screw plug 2 is provided with a hole 31. The discrimination object is arranged in the through hole of the screw plug 2. Wherein, the through hole of the screw plug 2 is communicated with the hole 31 of the zinc bar 3. When the zinc rod 3 corrodes the hole 31, the cooling medium 13 enters the through hole of the plug screw 2 and generates a discoloring reaction with the identification object, so that the replacement of the zinc rod can be prompted.
In one embodiment of the invention, the discriminant is a cotton strip 21. The length of the hole 31 of the zinc rod 3 is larger than the length of the tail part of the screw plug 2.
