The invention discloses a heat exchange plate, a battery module, a battery pack and electric equipment, and belongs to the field of batteries. The heat exchange plate comprises a refrigerant and a heat exchange flow channel, the refrigerant is arranged in the heat exchange flow channel, the heat exchange flow channel comprises an ascending flow channel and a descending flow channel which are communicated end to end, and under the condition that the temperature difference of the battery cells in the height direction is larger than a temperature threshold value, the ascending flow channel is used for passing through the refrigerant in evaporation or after evaporation, and the descending flow channel is used for passing through the descending flow channel. And the descending flow channel is used for allowing the condensed or condensed refrigerant to pass through. By arranging the ascending runner and the descending runner which are connected end to end, high-efficiency heat exchange of the upper and lower areas of the battery cell can be realized through high heat transfer capability formed by refrigeration evaporation-condensation circulation, and the overall temperature difference of the battery module is effectively reduced.
