New description: [New technical field] The present invention relates to a heat exchange device, and more particularly to a heat exchange device having a dry heater. [Prior Art] As shown in FIG. 1 , a heat exchange device includes a casing i, a heat exchange tube 2 disposed in the casing 1 for supplying and discharging fluid, and a casing The wet heater 3 has an inlet 埠1〇1 and an outlet 埠102' for secondary fluid in and out. Thereby, the primary fluid can enter the housing through the heat exchange tube 2 to exchange heat with the secondary fluid in the housing i, and the wet heating can be used to convect the housing. The primary fluid in i is heated. 4 because the operating temperature range of the hot parent changing device varies greatly (for example, -45 ° C ~ +80. 〇, and, the wet heating $ 3 will directly contact the secondary fluid in the casing 1 In addition, the secondary fluid is usually a corrosive special fluid. Therefore, the wet heater 3 often has a problem of leakage current and over-burning. In addition, when the wet heater 3 is to be repaired or replaced in the future, It is even more necessary to vent the secondary fluid in the casing, which may cause difficulty in repairing or replacing the work. Moreover, the wet heating of $3 is a special application heater, and its price is high, which also increases maintenance and repair. The cost of replacement. In addition, there is now a common plate heat exchanger, which has the advantages of small volume and high heat exchange efficiency. However, such plate heat exchanger cannot effectively heat the secondary fluid. Therefore, the applicability is not sufficient in applications where the temperature range varies greatly. 3 M398624 [New content] Therefore, the present invention provides a kind of dryness that can prevent the heater from coming into contact with the fluid. A heat exchange device with a dry heat exchanger comprising: a plate heat exchanger, at least a package heater, and at least one heat insulation layer. The electric heater is attached to the plate heat exchange The heat insulating layer is attached to the electric heater, and the heater is interposed between the heat insulating layer and the plate heat exchanger. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are as follows. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE PREFERRED EMBODIMENT Referring to Figures 2, 3 and 4, a preferred embodiment of a heat exchange apparatus having a dry heater of the present type has dry heating.
