In addition, my side still sets up a plurality of first mountings 111, and the one end of different first mountings 111 is connected with the different positions of acidproof heat-conducting plate 11, and the other end and the different positions of hot plate 12 of different first mountings 111 are connected for each position of hot plate 12 and acidproof heat-conducting plate 11 is all laminated as far as possible, and heat transfer effect is better, and the heat degree on the acidproof heat-conducting plate 11 is more even. It should be understood that some small protrusions may exist on the heating plate 12 and the acid-resistant heat-conducting plate 11 due to the processing precision, but the heating plate 12 and the acid-resistant heat-conducting plate 11 are pressed against each other by the action of the first fixing member 111, and the heating plate 12 and/or the acid-resistant heat-conducting plate 11 are slightly deformed to be attached to each other.

In some embodiments, the acid-resistant heat-conducting plate 11 is a graphite plate, and firstly, the graphite plate has a good heat-conducting property, and the acid-resistant property is good, so that the acid-resistant heat-conducting plate can be used as the acid-resistant heat-conducting plate. The acid-proof heat conducting plate can be made of graphite, ceramic or the like, and the disclosure is not particularly limited.
