The heat transferring plate is of a composite structure and is composed of a brazing filler metal layer and a base layer which are connected. The heat transferring plate and the evaporation pipe are welded together through the brazing filler metal layer. A plurality of through holes are formed in the parts, on the two sides of the evaporation pipe, on the heat transferring plate. The ends, close to the evaporation pipe, of the through holes are inner ends, and the inner ends of the through holes form a plane. A turned edge extending upwards is arranged at the joints of the heat transferring plate and the inner ends of the through holes, and the upper end of the turned edge is bent towards the evaporation pipe and is attached to the evaporation pipe. A first brazing filler metal layer is arranged on the side, facing the evaporation pipe, of the turned edge. The turned edge and the evaporation pipe are welded through the first brazing filler metal layer. Compared with the prior art, the exposed refrigerator evaporator has the advantage that due to the fact that the heat transferring plate and the evaporation pipe are welded together through the brazing filler metal layer, the heat transferring effect is better; the heat transferring plate of the evaporator is provided with the through holes, and therefore the convection of air in the refrigerator is improved.
