Problems solved by technology

In this way, there is a problem that the heat exchange efficiency decreases due to the incorrect formation of the ventilation path on each heat transfer plate 102 due to the wrong stacking of the gaskets 101, and it is required to prevent the heat exchange caused by the inability to correctly form the ventilation path. efficiency reduction
[0009] In addition, since the heat exchanger 109 alternately stacks the gaskets 101 in the same direction, the gaskets can be connected and held even in the wrong stacking direction, so there are production defects such as stacking errors, and mass production is difficult. To reduce such problems, it is required to improve mass productivity by eliminating stacking errors per unit component

Abstract

The present invention provides a heat exchanger for exchanging heat through heat transfer plates by flowing a primary airflow and a secondary airflow in air passages. The heat exchanger comprises a unit element having a heat transfer plate and an air passage formed between the heat transfer plates by stacking the unit elements. Each of the unit elements is structured by molding a space rib for holding the space between the heat transfer plates integrally with a shield rib for shielding the leak of the airflows by use of a resin. The unit element includes an error detection part which can easily detect an error in stacking when the unit elements are stacked.

Description

technical field [0001] The present invention relates to a heat exchanger with a laminated structure used in a heat-exchange ventilation fan for households and a total heat-exchange ventilator for buildings and the like, and a method for manufacturing the same. Background technique [0002] Heretofore, this type of heat exchanger has been formed by laminating heat transfer plates and gaskets without joining, in order to improve basic functions such as ventilation resistance and heat exchange efficiency while reducing manufacturing costs. For example, it is disclosed in Patent Document 1. Below, refer to Figure 20A , Figure 20B , Figure 21 This heat exchanger will be described. [0003] As shown in these figures, the spacer 101 made of synthetic resin is arranged on the spacer ribs 103 and the connection ribs 104 by spacer ribs 103 for maintaining the space between the heat transfer plates 102 and the connection ribs 104 for connecting the spacer ribs 103 to each other. ...
