Heat exchanger structure with flow divider

Abstract

A heat exchanger structure with flow divider includes a heat-conductive main body provided with a flow passage having at least one inner turn and one outer turn, and at least one flow divider located near and downstream the inner turn, such that a cooling liquid in the flow passage flowing through the inner and the outer turn to reach at the flow divider is divided by the flow divider into two smaller flows. Therefore, the cooling liquid in the flow passage has reduced pressure drop and it is not necessary to increase the operating power of a pump that delivers the cooling liquid into the flow passage.

1 . A heat exchanger structure with flow divider, comprising a heat-conductive main body being provided with at least one flow passage having at least one inner turn and one outer turn; and at least one flow divider being located near and downstream the inner turn, such that a length of the flow passage with the flow divider is divided into at least a first sub-passage and a second sub-passage. 
     
     
         2 . The heat exchanger structure with flow divider as claimed in  claim 1 , wherein the heat-conductive main body is provided at predetermined positions with an inlet and an outlet; and the inlet and the outlet separately communicating with two opposite ends of the flow passage. 
     
     
         3 . The heat exchanger structure with flow divider as claimed in  claim 1 , further comprising a cover for assembling to an open top of the heat-conductive main body to close the latter, so as to complete the flow passage in the heat-conductive main body. 
     
     
         4 . The heat exchanger structure with flow divider as claimed in  claim 3 , wherein the flow passage has a bottom, on which the at least one flow divider is provided to extend toward the cover, so that the bottom of the flow passage, the flow divider, and the cover together define the first sub-passage and the second sub-passage in the flow passage. 
     
     
         5 . The heat exchanger structure with flow divider as claimed in  claim 4 , wherein the at least one flow divider is in contact with the cover, so that the bottom of the flow passage, the flow divider, and the cover together define the first sub-passage and the second sub-passage in the flow passage. 
     
     
         6 . The heat exchanger structure with flow divider as claimed in  claim 3 , wherein the at least one flow divider is provided on the cover to extend downward into the flow passage, so as to define the first sub-passage and the second sub-passage in the flow passage. 
     
     
         7 . The heat exchanger structure with flow divider as claimed in  claim 6 , wherein the at least one flow divider is in contact with a bottom of the flow passage. 
     
     
         8 . The heat exchanger structure with flow divider as claimed in  claim 2 , wherein the inlet on the heat-conductive main body is connected to an end of at least a first pipe, which is further connected at another opposite end to a pump; and the pump is further connected to an end of at least a second pipe, which is further connected at another opposite end to the outlet on the heat-conductive main body. 
     
     
         9 . The heat exchanger structure with flow divider as claimed in  claim 1 , wherein the first sub-passage has a width larger than that of the second sub-passage. 
     
     
         10 . The heat exchanger structure with flow divider as claimed in  claim 1 , wherein the flow divider has an upstream end being formed into a pointed end.
